We Listen Part 1 – How the S3CHL Pump came to be

I’m sure you have heard the term “Necessity is the Mother of Invention”. For us at Hydra-Tech Pumps it means we are always listening to our customers’ needs and requests for pumps and hydraulic power units that will meet specific requirements. Most of the time this means offering the right combination of hydraulic submersible pump and hydraulic power unit to address a challenging application. Once in a while it leads to something else.


Sometimes these ideas or challenging applications result in the development of new products that we can offer as a standard product. One case in point is the S3CHL pump. Sometime in 1987 a customer in Jacksonville Florida approached Hydra-Tech Pumps looking for a pump that would provide flows over 400 GPM, discharge pressures up to 175 PSI, fit into a 12” deck opening, portable enough to be carried by one person and handle a wide range of water and oil mixtures. This pump would be used for tank stripping and emergency tank transfer on tanker ships. We developed the S3CHL pump to do just that and more. This pump has found its way into other applications such as firefighting, deep well dewatering and irrigation.

The S3CHL is available in aluminum or ductile iron and needs a maximum hydraulic flow of 30 GPM at 3500 PSI for full performance. But what performance you will get! This pump will deliver 500 gallons per minute with no head, but will still deliver 50 GPM @ 420’ of head! That’s a lot of capability from a small pump.


“It pays to listen” and we hear you. Part of our job is to solve problems for customers. Sometimes the solution lies with a combination of existing products, sometimes the solution involves a referral to someone else’s product, and sometimes the solution needs to be developed. Do you have any challenging applications that we can help you solve?
