The A.I. McDermott Co., Inc. and its McDermott Pump and Lyon Pumps locations have partnered with Grundfos Pumps to serve as Grundfos’ authorized large 4” submersible motor distributor in Wisconsin, Upper Michigan and Northern Illinois.

The Grundfos MS4000 Series motor is the result of over thirty years of research and development by Grundfos.  The MS4000 motors have NEMA standard mountings which means they will power any NEMA standard liquid end in the Industry – making them perfect for new installations or as replacement motors on existing installations.

The Grundfos MS4000 submersible motors use a 1500 lb Mitchell type thrust bearing with carbon pads coupled with a ceramic thrust runner.  The motor’s mechanical seal made of ceramic and tungsten carbide protect the motor from sand damage.  Grundfos’ unique internal water circulation system enhances motor cooling and corrosion resistance is ensured with the motor’s AISI 304 stainless steel construction.

McDermott is stocking the MS4000 motors in 2, 3 and 5 HP in single and three phase in all voltages.

The Grundfos MS4000 motors are priced competitively and provide the only proven 2 HP and larger 4” motor alternative to Franklin Electric.

Please contact your McDermott or Lyon Pumps sales representative for more information and the specifications needed to quote the MS4000 on your next large 4” submersible pump job.
