Torpedo Pump

Pumps Unlimited’ s flagship product, The Torpedo Pump, is an established high-efficiency feed pump for Reverse Osmosis Purification Water Systems. The Torpedo Pump has served our customers well, and for a long time, some of our pumps in the field are 30 years old and keep pumping away.

Design: The Torpedo Pump utilizes a multi-stage stainless steel turbine pump end driven by a stainless-steel submersible motor via a splined connection. The Torpedo Pump’s design is customizable, allowing it to serve various needs outside of water purification; one example is that we can modify the Pump for dewatering applications.

The Torpedo Pump is available in all sizes ranging from 2 to 1200 gallons per minute or GPM, with discharge heads up to 1,900 feet. The horsepower from our motors range from 5 to 150 horsepower. Please see our 60Hz and 50Hz selection guides or contact us for a quote.


The Torpedo Pumps design allows it to function horizontally and vertically mounted, allowing our customers to have more flexibility with the space constraints they may have for housing.
The enclosed pump features allow it to operate at a quieter volume than other R.O. pumps.
The Pump can be easily serviced and we provide quality support to our Torpedo Pump owners.
This Pump will save you money and time as it requires no field alignment, no scheduled maintenance, and no required spare parts.
