FEATURES
  • Patented Water Bearing Technology – feed water lubricates and cools the integral thrust bearing for long bearing life in the harshest of conditions.
  • All Super Duplex investment cast construction – meets or exceeds corrosion resistance requirements in all SWRO applications.
  • Rotatable inlet connection – horizontal or vertical feed inlet pipe connection.
  • Mechanical Seal Cartridge – easy and fast seal maintenance.
  • Precision leveling feet – easy motor alignment without the need for skilled labor or expensive equipment.

Loaded with unique features such as the patented Water Bearing™ product lubricated bearings, Super Duplex stainless steel construction, and maintenance-free design ensure years of trouble-free operation. No need for several pumps in parallel, the MSD line has a pump feed flow capacity range of 20 to 560 m3/h and efficiencies up to 86%.

MSD Low Flow models: MSD-40, MSD-70, MSD-130 with shelled design with Super Duplex Shell and shaft, Super Duplex stages standard, baseplate optional.

MSD High Flow models: MSD-160, MSD-200, MSD-350, MSD-400 bolted stage design with Super Duplex shaft and stages standard, Super Duplex material optional, baseplate optional.
