Product details

The C105-238PLAZ is the 3 horsepower full rate impeller assembly used in the IntelliPro VS 3050, along with the Max-E-Pro, Max-E-Glas II Series and Dura-Glas II Series inground pumps.

Get the rating right

Pump manufacturers build the same housing in full rate and up rate versions, and the impeller is what separates them. Two pumps with 3 on the label can move noticeably different volumes of water. This is the full rate impeller, so check the rating stamped on the part you are replacing before ordering, since fitting the wrong one changes the pump curve and can leave the system either starved or overworked.

When the impeller is worn

An impeller wears from the inside. Sand and grit passing through the vanes opens up the clearances until the pump is turning at full speed while moving less water. The usual symptom set is weak returns, low filter pressure and a slow cleaner, all while the motor sounds fine. Debris packed into the vanes causes the same thing suddenly rather than gradually, so pull the impeller and look through the vanes before assuming it is worn out.

While you are in there

Removing the impeller means separating the seal plate and exposing the shaft seal. A seal that has been disturbed rarely reseats reliably, so plan on fitting a fresh one and a diffuser gasket during the same job.

Questions and answers

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

What is the difference between full rate and up rate?
They are two ratings of the same pump body with different impellers. Full rate and up rate models with the same nameplate horsepower move different amounts of water, so the impeller has to match the pump you own.
Which pumps does it fit?
The IntelliPro VS 3050 along with the Max-E-Pro, Max-E-Glas II Series and Dura-Glas II Series inground pumps.
Do I need a new shaft seal too?
The impeller has to come off the motor shaft to be changed, which exposes the shaft seal. Most techs replace the seal at the same time rather than reusing a disturbed one.
How do I know the impeller is the problem?
Weak flow and low filter pressure with a motor that still runs normally usually points at the impeller, either worn open vanes or debris packed into the vanes.
