Is the SuperFlo 2 HP Single Speed Pump - 340040 California Title 20 compliant?

A  Answered on 6/18/2019 by InyoPools Product Specialist Lennox H.

Hi, Thomas. This SuperFlo Pump - 340040 is NOT California Title 20 compliant. You will need to use the SuperFlo 2 HP Dual Speed Pump - 340044

I have this pump 340040 ........with motor B2854 installed. Ran fine now shaft turns but no movement in the front end. New customer so he knows nothing about who did what. Just trying to determine right setup as shaft or diffuser or impeller may all be broken.


A  Answered on 5/25/2019 by InyoPools Product Specialist Lennox H.

Hi, Andrew. The SuperFlo Pump - 340040 is a 2 HP model, however, the B2854 is a 1.5 HP motor so the impeller had to be changed to match the B2854 motor. If you want to replace the entire pump, use model # 340039 or with the original 340040

What's the difference between a superflo 2hp and whisperflo 2hp? If they both have the same SF do they perform the same? I need to know if the pump will have adequate pressure for my in-ground cleaning system to work.

A  Answered on 3/5/2019 by InyoPools Product Specialist Lennox H.

Hi. The difference between the Superflo and Whisperflo pumps is the performance. The Superflo is a medium head pump and the Whisperflo pump is a high head pump.

Hello, I have a Pentaire Whisperflo pump and the info on the case is. Century Centurion 2.3 HP 177452-03. What model do you have for a = cross and part number along with P&A. Thank you, Rick

A  Answered on 3/5/2019 by InyoPools Product Specialist Lennox H.

Hi, Rick. The Superflo Pump is not a good replacement for the Whisperflo Pump. I would recommend the Whisperflo Pump - WFE-8.

I have a WhisperFlow 2HP (011515) and would like to replace with a Superflow 2HP (340040). The WF is a 208=230V vs the SF 115/230V. Is it comparable and can be electrically installed with ease.

A  Answered on 1/18/2019 by InyoPools Product Specialist Lennox H.

Hi, DM. You can use the Superflo Pump if you have 230 volts. Replacing the Whisperflo Pump with the Superflo Pump, you will see a big difference in water flow performance.

Can i replace a SuperFlo 1 1/2 HP Single Speed Pump motor with a SuperFlo 2 HP Single Speed Pump motor?

A  Answered on 1/27/2017 by InyoPools Product Specialist Scott W.

You can but you will have to upgrade your impeller as well. Also, you would need to calculate what your estimated flow rate is because you do not want to increase your flow rate if your filter cannot handle the increased pressure.
