Product details

The Stenner MSK120 is the motor service kit for the 45, 85, 100 and 170 Series pumps, in both adjustable and fixed output versions. It is the 120 V, 60 Hz version with a 2 inch NPT mount.

What a service kit is for

Stenner feed pumps run continuously, and after enough hours the motor is what starts to go: output falls off, the pump gets noisy, or it stops turning under load. A motor service kit puts that right without replacing the whole pump, which is the difference between a modest parts order and a new unit plus the plumbing work to fit it.

Matching the kit to your pump

Three things have to line up: the pump series, the voltage and frequency, and the mount. This kit is for the 45, 85, 100 and 170 Series at 120 V and 60 Hz with a 2 inch NPT mount. Stenner also describes it as the motor service kit for the Classic Series pumps, which is the family those series belong to. Read the data plate on your pump and confirm all three before ordering.

Questions and answers

What people ask about this product, answered by our pool techs.

Which pumps does this kit fit?
Stenner lists it for the 45, 85, 100 and 170 Series, in both adjustable and fixed output versions. The same kit is also described as the motor service kit for the Classic Series pumps.
What voltage is it?
120 V at 60 Hz. Stenner uses different part numbers for other voltages, so match the plate on your pump.
What does 2 inch NPT refer to?
The motor mount thread. Confirm the mount on your existing pump before ordering, since it determines whether the kit lands correctly on the housing.
Is it worth servicing the motor instead of buying a new pump?
Usually yes. A peristaltic feed pump that has lost output or become noisy is often a motor problem rather than a whole pump problem, and a service kit costs far less than a replacement unit.
