Product description The Grundfos MS6000 product range is a complete range of asynchronous submersible motors from 4 kW up to 30 kW in 50 and 60 Hz versions and synchronous submersible motors from 4 Kw to 45 kW in 3000 rpm and 3600 rpm versions. The following material versions are available: • a standard version made of stainless steel EN 1.4301 (AISI 304) • an R-version made of stainless steel EN 1.4539 (AISI 904L) for aggressive liquids such as seawater and mine water. The Grundfos MS6000 submersible motors are designed according to market standards. All Grundfos MS6000 motors are designed to fit pump ends manufactured in compliance with the NEMA standards, therefore, they can be fitted on all Grundfos SP pumps without adapters. The motors are also available with a flange extension allowing for fitting pump ends from other manufacturers. General characteristics of the MS6000 motor: • outside diameter (OD): 6 in (139.5 mm) • high efficiency • stator completely encapsulated in stainless steel • cooling by pumped liquid • hermetically sealed, canned motor with a dry stator • enclosure class IP68 • factory fill with Grundfos motor liquid SML-3, alternatively with demineralized water • built-in temperature transmitter (Tempcon) on the asynchronous motors. The motor temperature can also be monitored via a Pt100 sensor (used for frequency controlled installations).
