Hi. I have a pentair 1.5 hp pump that appears to be driving the pressure up on the filter. The old pump was 1 hp. What impeller do I need to change down to 1hp

Hi, Jamison. To reduce the pump performance, you will need to replace the Impeller - 355067 and Diffuser - 355617 along with new seals which are apart of the SuperFlo Tune Up Kit - GOKIT78.

    Thanks for the info. Do you think it may be easier to use some sort of flow control device to the filter? What that put more strain on the pump? Any ideas what type of flow control would work?

      Jamison, There is not a flow control device that can be used other than a variable speed motor -  ECM16SQU. It can put strain on the pump motor causing it to fail prematurely or overheat.

I am replacing a 3/4 hp whisperflo motor WFE-3, SF 1.67 with a 1 hp SF 1.65. Do I need to replace the impeller, if so, will this one work? Thanks.

Hi, Ernie. This Impeller - 073128 is the correct size to use with a 1 HP 1.65 SF motor if you would also like increase water flow. With the increased water flow, you will have to make sure your plumbing and filter is large enough and the water flow does not exceed the flow rate of your heater.

    Great thank you! Yes, plumbing is 2" and 60 SF DE filter. The pool is quite big and I was wondering why we were always fighting algae in the summer. I am guessing because the motor being replaced is only 3/4 HP.

Can I use this impeller on a 1.5 HP motor?

What is your pump model and what is your motor part or model number and I can recommend the correct impeller?

Does this impeller come complete with screw to attach it to the motor shaft, or does the screw have to be purchased separately?
 Reply

Mark, The Set Screw for the Pentair Whisperflo impeller is sold separately.

Will this impeller (073128) fit the WFK-4 1hp 3-phase Pentair Whisperflo pump?
 Reply

A  Answered on 10/23/2014 by InyoPools Product Specialist Robert M.

Yes, Pentair part number 073128 is the correct impeller for the WFK-4. It will also work on the WFE-4, WFE-26, WF-4, WF-26, WFDS-4, WFDS-26.

Can impeller part# 073128 be used on motor B864SE?

Part number 5074-27b would be the correct impeller for that motor.
