Operating Conditions MS Motors Operating Conditions Cooling The cooling of the motor depends on the temperature and the flow velocity of the pumped liquid past the motor. To ensure sufficient cooling, the values for maximum temperature of the pumped liquid and its flow velocity must be kept.

Pumped Liquids The MS 4000 motors are available in several versions to enable use in various liquids. • MS 4000 is generally recommended for use in water without chloride. MS 4000 is made of 304 stainless steel AISI • MS 4000 R is recommended for use in aggressive liquids.
Page 13
• MS 6000 RE is recommended for use in aggressive and slightly contaminated liquids. MS 4000 RE is made of 904 stainless steel AISI, and the rubber parts are made of FKM. In cases of doubt, please make an analysis of the liquid and contact Grundfos.
