One of the things Hydra-Tech Pumps is known for is our customization – at our website and in our catalog are two long lists of options that are available for both hydraulic submersible dewatering pumps and hydraulic power units, from custom paint to custom design.  As we have done before, we wanted to highlight another pair of customer designs.

A brand new prospect contacted us on April 23rd.  He works in a pretty serious machine shop down south and was looking for an electric HPU to replace an existing (you might say antique) unit that was supporting a broaching machine.  With some pictures of the existing unit in hand we had two maybe three phone calls to nail down the details and provided a quote to this prospect on 4/29, and after some additional changes, a revised quote on 5/1.  An order was placed on 5/6 and after the 3-4 weeks to get some of the materials in including the JIC reservoir upon which the unit would be built, we designed, built and tested a one off, multi circuit, custom electric hydraulic power unit in 5 weeks.  We would have turned it around in about half that time if not for a recalled electric motor that needed replaced by a supplier.

Speaking of completely custom, we were challenged by a valued, longtime customer to develop a brand new design based off of their very specific needs.  In general terms we designed and built a 50 horsepower electric hydraulic power unit in a sound attenuated enclosure that will be used on ships all over the world performing salvage operations.

The customer asked us to perform some pretty significant heat testing.  So once the unit was built and ready plans were made and a date for the test was set.  On Wednesday July 8th, with personnel from both companies on hand at Hydra-Tech Pumps’ facility, we got started early in the morning with the testing.  As the temperature out on the blacktop climbed up to close to 100 degrees we ran the unit for 3 hours under load and monitored oil and motor temperatures and performance.

In case this wasn’t enough, an ever tougher heat test was required by the customer.  This unit could potentially be sitting on the deck of a ship at the equator with an ambient temperature of 115 – 120 degrees.  To allow us to create this environment for the test, we had to build a temporary structure inside of our building that would allow us to place the unit inside and with the help of some heat lamps and a propane area heater, bring the temperature up to 120 degrees Fahrenheit and maintain that temperature for the duration of the test.

The power unit sat in the enclosure with the ambient temperature being monitored.  The hydraulic hoses ran outside through a small hole in the wall of the enclosure, out a door and to a pump that was actually moving water against a simulated head in our outdoor test tank.  This allowed the power unit to work as hard as it would in a real world scenario to really test the ability of the hydraulic oil cooler.  Three hours later and with both tests successfully completed, the customer left our facility confident that the unit we built would be able to survive a worst case temperature scenario and continue to perform while the salvage divers in the water who rely on its hydraulic power could continue to operate their equipment.

 

 

 

 

 

At Hydra-Tech Pumps we are not afraid to go above and beyond for our customers.  In some cases, that means a lot of time effort and work going into a one off unit that will likely never be built again.  In other cases it means that we come up with a completely new design for a loyal customer that will perform under pressure.  New designs always bring about a unique set of challenges.  New designs aren’t easy – they tend to present new problems in the testing stages.  But we see them through to the finish and deliver a system that satisfies a customer’s needs, even if it’s the only one we’ll ever build.  Do you have a custom hydraulic power unit design need that no one else will consider?  Give us a call and let’s see if we can do it – I bet we can!

 

 

 

 

 

 

Note: We are talking specifically about the hydraulic hoses used to connect the pressure and return ports of the hydraulic power unit to the pump. If you were to replace a hydraulic line on the hydraulic power unit itself refer to the hose you are replacing and / or consult with the factory first.
There are lots of options when it comes to hydraulic hoses – there are 16 different SAE standards with some additional options within some of the 16. There were originally 19 but three (100R9 through 100R11) are no longer a part of the SAE standard. Most of the options from standard to standard are related to the following parameters:
Size.
Type of hydraulic fluid being used.
Working Pressure (Pressure Rating).
Temperature Rating.
Physical Makeup of the outer cover (as it relates to UV, chemical resistance, abrasion, etc.)
Type of end fittings that will be used, specifically, whether the installation of chosen fittings requires skiving (removal of outer casing of hose) before installation.
Conductive / Non- Conductive.
           The majority of the systems that Hydra-Tech Pumps manufactures don’t exceed 3000 PSI and as a result we offer 100R12 and 100R17 hydraulic hose rated for 3000 PSI all with abrasion resistance covers. We believe that the hoses we supply offer a good mix of safety, durability, and wear and UV resistance for our customers and that they are good general purpose hoses for use with our pumps and hydraulic power units.

Mounted on the side of the hydraulic oil reservoir on any standard Hydra-Tech Pumps Hydraulic Power Unit is the H.C. (or Hydraulic Control) Valve. The only exception to this is sound attenuated units. Since access to the hydraulic oil reservoir is limited, sound attenuated units do NOT have a H.C. valve. Think of this valve as an “on / off” switch for the hydraulic circuit on your HPU. Once an HPU has been started and warmed up and you are ready to send hydraulic fluid to a pump (or hydraulic tool) properly connected with hydraulic hoses, or deadhead the unit (troubleshooting), this valve should be turned all the way clockwise until the handle stops to engage the hydraulic flow. When you are ready to shut the system down, the H.C. valve should be turned all the way counterclockwise until the handle stops to shut off the hydraulic flow. This valve should not be used to attempt to control flow as doing so will generate heat and cause other problems. If you need to control flow or pressure, Hydra-Tech Pumps offers flow and pressure controls for their pumps and an adjustable inline flow control device as well.

Hydra-Tech Pumps uses a variety of different hydraulic pumps on their hydraulic power units – the choice of pump is typically determined by the customers’ needs. Hydraulic pumps that we use are either fixed displacement or variable displacement. So what is the difference between the two?
Fixed Displacement Pumps. Gear, vane and some piston hydraulic pumps deliver the same displacement per revolution and cannot be adjusted. Adjustability with a fixed displacement pump is done only with engine RPM. If you were to match a Hydra-Tech Pumps power unit to a pump or tool where the maximum potential flow and pressure of the HPU will not exceed the maximum hydraulic flow and pressure the pump or tool is able to use, there would be no need to adjust the hydraulic flow and pressure that the hydraulic pump on the power unit delivers.
Variable Displacement Pumps. Variable displacement piston hydraulic pumps can be adjusted to provide a range of flows and pressures (all determined / limited by the horsepower of the engine or motor that is driving it). If you were purchasing a hydraulic power unit to run multiple pumps (or other hydraulic tools) with a range of hydraulic requirements, having a variable displacement piston pump on your HPU is essential. A typical 74 horsepower diesel engine HPU with a variable displacement pump would be set up at Hydra-Tech Pumps for 30 GPM @ 2900 PSI. There are a number of Hydra-Tech pumps that will run at this flow and pressure, but if you had a pump or hydraulic tool that had a max flow and pressure of, for example, 20 GPM @ 2700 PSI, you could make adjustments to the piston pump to “reset” your HPU to run this piece of equipment. Keep in mind that this change would require a flow meter and some hand tools and is not something that is done by simply turning a knob or adjusting a setting in a control panel – this adjustment is actually altering the geometry of the displacement chamber which in turn affects the flow and pressure that the pump delivers.
We thought we would keep you up to date on our building addition – even though the construction part is done there is still a lot of work to be completed on the inside! The picture below gives you a look at some of the work that has been accomplished in between manufacturing pumps and hydraulic power units and everything else that goes on at Hydra-Tech Pumps week in and week out. The 8000 square feet of new space will house a combination of production space, warehouse space, finished product testing space (including our new pump test tank), our loading dock and ground level doors and shipping and receiving department.
As the birds begin to make an appearance and spring is threatening nice weather soon in Pennsylvania, we are excited to continue to work on this space and make it work for us when we’re done. We will provide additional updates and pictures as we make progress.
The hydraulic motor. It works hard to convert the flow and pressure of hydraulic oil into work. In the case of Hydra-Tech’s dewatering pumps, this work is pushing a column of water out the discharge and through the hose / piping to its intended destination.
Every hydraulic motor has a pressure inlet and a return outlet (and sometimes a case drain port – but that’s a subject for another time). At Hydra-Tech Pumps we try to stamp P for pressure and R for return on all motors on all pumps built, and on all motors sent as spares. Hydra-Tech Pumps does use some hydraulic motors on our pumps that are bidirectional and the direction in which the impeller spins is determined by which port you connect pressure to. This too is a subject that we will cover in another blog.
In this post we’re going to focus on unidirectional hydraulic motors which are the majority of what we use on our pumps. These hydraulic motors are not symmetrical, and as you will see below, we reference the heavy side of the motor (as you look at the back of the hydraulic motor). Knowing which port is the pressure inlet and which port is the return port is important, as switching the pressure and return will result in many potential problems from spinning the impeller in the wrong direction, spinning the impeller off of the shaft, and blowing motor lip seals and mechanical seals while dumping lots of hydraulic oil into the body of water where you are pumping.
To help avoid such problems, when you buy a complete system from Hydra-Tech Pumps the quick disconnects / oilfield connections from the pressure connection of the HPU reservoir to the pressure inlet of the pump’s hydraulic motor and return connection from the pump’s hydraulic motor back to the return connection at the HPU oil reservoir are set up to prevent misconnection.
The following statement is true except for the hydraulic motors we use on most axial flow pumps, all 6000 series pumps, slim line pumps, screw pumps, and the S3CML, S3CHL, S4CHL, S8T and S10T. To help yourself deal with a problem in the field, there is a way to tell, on a hydraulic motor used on any Hydra-Tech Pump with a unidirectional hydraulic motor – it has to do with what we refer to as the heavy side of the motor. If you needed to identify the inlet (pressure) and return ports of a motor for any Hydra-Tech Pump (except for exceptions listed above) you would refer to the following drawing:

Last year went by quick – we talk about it every year, but it felt like it went from February to November in the blink of an eye and on through the holidays and the end of the year. Granted, we were busy and when you’re busy time always seems to move more quickly.
Although we didn’t hit our budgeted sales goal for 2019, we did manage to beat 2018’s sales number to achieve Hydra-Tech’s best sales year ever. We shipped orders all over the United States and all around the world. In the 12 years at our current location we have averaged export sales of about 20% as a percentage of total sales. We appreciate our customers’ loyalty to our products and the service we provide.
The other major thing that Hydra-Tech accomplished in 2019 is that we increased our manufacturing space by 44% – adding 8,000 square feet of additional manufacturing space to the 18,000 square feet we have been working out of since moving the business to its current location in September of 2007. With ever increasing sales volume over the last 4 years, one of the challenges that we have faced was space. Our new space will be a combination of warehouse space and manufacturing space that will allow us to increase efficiencies related to our production.
We’re three weeks into 2020 and yes- it seems to be moving faster than 2019 already. But we have big goals. 3 trade shows, and lots of customers to satisfy. The World Pumps Us for Solutions – and we have to be on our toes and ready to find solutions for those customers new and old.
As a business, here is a list of the things we are thankful for as we get ready to close down Thursday and Friday so that our co-workers can travel near and far to spend time with their families.
  • Hydra-Tech Pumps is thankful that through the efforts of our employees we have been able to grow the business consistently since our move in 2007 to the point where we are putting the finishing touches on an 8000 square foot addition. We expect to be using the space in January 2020.
  • Hydra-Tech Pumps is thankful that we have never been in a position to have to have layoffs.
  • Hydra-Tech Pumps is thankful for our customers, big and small, domestic and international – your loyalty to our pumps and hydraulic power units has helped us to have fairly consistent growth through the years.
  • Hydra-Tech Pumps is thankful for our vendors who have supported our efforts and contributed along the way.
  • Hydra-Tech Pumps is thankful the our founder, Ken Reim, is still very active on a daily basis and involved in Research and Development, Sales, Technical Support and is such a valuable resource to our whole group.
  • Hydra-Tech Pumps is thankful for our employees. As we try to stress at any company event, Hydra-Tech Pumps succeeds or fails based on the efforts of every employee no matter the title or responsibility – we are all tied to the success or failure of the business based on the quality of the product we make, the communication with the customers, and the customers’ perceived value of what we provide to them.
A recent email to some friends who visited Hydra-Tech Pumps and toured the business included the following statement: “Our growth and success is the result of a lot of things, some hard work, some good fortune, and lots of good people (employees, vendors, customers) who have helped us along the way.” For that statement Hydra-Tech Pumps is thankful.
So to anyone reading this we would like to remind you to enjoy the time off this week with your family and friends. On a personal level, the things that I am most thankful for are family, friends and health – I’d be willing to bet that your list is similar if not the same. (Jeff Whittaker, VP Sales and Marketing)

                                                                                                     

As we celebrate Veterans Day today, I don’t think it would be a stretch to say that most people know at least one veteran.  A family member, friend, former classmate, I bet that everyone knows someone who has served in a branch of our great country’s military.  Hydra-Tech Pumps currently employs 22 people and our group includes four veterans.

 

Kyle Whittaker, Hydra-Tech’s President, served in the Army for three years and spent time in both Korea and Vietnam.  Andy Falco our VP of Manufacturing spent 4 years in the Marines.  Darryl Cunfer the Manager of Product Development and Training spent 4 years in the Army.  Tim Frye, one of Hydra-Tech Pumps’ machinists, spent 3 years in the Navy and 2 years in the reserves as a Corpsman.

On Wednesday November 6th the Lehigh Valley Phantoms, the AHL affiliate for the Philadelphia Flyers hosted Military Appreciation Night.  Because of our ties to veterans, Hydra-Tech Pumps sponsored 50 tickets for veterans to attend the game.  In all, there were over 3,160 tickets donated for veterans to be able to attend the game.

 

Because we participated in the sponsorship, we were provided 4 tickets to use for the game.  We chose to send our own veterans down and three of our four veterans were able to attend.  Rounding out the group was Darryl’s grandson, who got to enjoy his first Phantoms game.  The Phantoms provided a win for all in attendance, they beat the Wilkes-Barre Scranton Penguins by a score of 4-2.

 

 

We would like to thank all active military personnel who are currently serving and all veterans for their service to our country.  We are proud of your sacrifices.

Question: Which is the most popular horsepower level from the wide variety of hydraulic power units that Hydra-Tech Pumps offers?

 

Answer: Our 74 horsepower HPU, delivering a maximum output of 30 GPM at 2900 PSI (other settings available) is far and away the most popular for contractors and rental companies. One of the reasons is it so desirable is the lineup of distinctly different pumps that can be paired with it – we have 10 different pumps offering a wide variety of general and specialized dewatering capabilities that run at peak performance with this 74 HP unit.

 

           So the next question that comes to mind is what could we do to make this combination of products any more appealing? Some of our customers have tried to run our S8T with a 74 horsepower – unfortunately the two don’t play nice together. 30 GPM will spin the S8T’s impeller but customers never came close to the full performance that 70 GPM and 2500 PSI would deliver. The answer to the question is the new Hydra-Tech Pumps S8TC currently in development and expected to be in production in spring.

 

           With a design point of 2500 gallons per minute and a shut off head of 85 feet, the S8TC will be the perfect addition to any company’s service / rental fleet and another great pump to compliment the 74 horsepower hydraulic power unit. The pump will be available in ductile iron first and eventually in an aluminum body option – both versions would feature a stainless steel impeller. Typical of most Hydra-Tech Pumps, the bolt pattern for the strainer on the bottom matches that of an 8” ANSI flange allowing for additional flexibility in how and where it can be used.

 

 

 

 

 

 

 

 

          We expect to have the S8TC at the ConExpo Show in Las Vegas in Hydra-Tech Pumps’ booth #C31094. As we get closer to production and availability there will be a follow up in the newsletter as well as some direct emails – both will have a spec sheet and pricing when available. Would you like us to put your name on a list of customer interested in the S8TC? Please send an email to htpump@hydra-tech.com with S8TC in the subject line and just drop your signature into the email and send. We’ll keep you up to date on our progress and you’ll be the first to receive the spec sheet and pricing when it becomes available.
