MSS pumps are multistage centrifugal feed pumps specifically designed for brackish and seawater reverse osmosis service, representing the most reliable high-pressure feed pump available today.
Loaded with unique features such as the patented Water Bearing™ thrust bearing, product-lubricated shaft bearings, and maintenance-free design, the MSS ensures years of trouble-free operation. The MSS also features one of the longest warranties in the industry – a full 18 months of coverage from the date of product installation.

High Inlet Pressure Option
All MSS pumps can be equipped with high inlet pressure option to allow inlet pressure to 70 bar.
This unique design features:
- Use of low-cost, standard mechanical seals, operating at a low pressure (typically 1-2 bars)
- Total protection of the motor from pump thrust loads – a major problem with high inlet pressure operation
- Pump shaft kept in tension – no potential for shaft buckling
- Handles total axial thrust – no load on motor bearings
- Never needs lubrication
- Bearing cooled by feed water – no ambient temperature limit
- 316L SS stages, passivated and electropolished
