Introduction
Grundfos MS Motors Introduction
Grundfos Submersible motors are designed specifically
for operation in and under water.
The motor and power cable are designed and sealed to
prevent water from contacting any part of the electrical
circuit.
The motors are equipped with a high-capacity thrust
bearing to support the total thrust of the pumping unit.
The Grundfos submersible motor depends on
surrounding water to carry away heat; most require a
specified flow of water for adequate cooling.
MS Motor Selection
Selecting the best submersible motor for a particular
pump application requires careful consideration of
several factors. The motor must match the pump in
mounting dimensions, and must also have adequate Hp
load rating and thrust rating to support the pump over
its entire operating range. Grundfos 4” and 6” submers-
ible motors are built to NEMA standards, which define
their physical dimensions, electrical ratings, and thrust
ratings. The motor must be capable of operation at the
water temperature and velocity presented by the instal-
lation.
Grundfos literature specifies the maximum water
temperature and minimum required velocity past the
motor. Motor operation in water that exceeds the rated
temperature may be allowable at reduced loading,
depending on the particular motor.
If the installation does not assure the specified velocity
past the motor- because of well diameter, well inflow
above the pump or other reasons - a sleeve over the
motor should be used to induce the required velocity.

Operating Conditions
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.
It is reccomended always to ensure a minimum cooling
flow of 0.50 f/s.
Free Convection
Free convection is achieved when the diameter of the
borehole is at least 2" (~ 50 mm) bigger than the outer
diameter of the motor.
The motor should always be installed above the bore-
hole screen. If a flow sleeve is used, the motor can be
placed in the screen.
Calculation of the flow velocity:

Qmin: Flow in gpm
