Inyo Recommended Pumps

Challenger® High Flow pumps are designed to deliver increased flow rates needed in more demanding applications. And they deliver extra pumping power while minimizing energy use. These fiberglass reinforced pumps feature closed impellers and durable custom-molded thermoplastic components to meet the toughest operating conditions and keep on going. Thanks to a proprietary hydraulic design that’s been refined for over 40 years, the Pentair Challenger pump delivers superior performance using smaller horsepower motors that cost far less to run. For challenging applications where high flow rates are required, Challenger has set the industry standard for quiet, rugged reliability. Beyond efficiency, the top criteria for your pump should be long, trouble-free life and easy service which, Challenger pumps can give you year after year.

the motor i have with this pump (CHII-N1-1A) is not working anymore, what are my choices for replacement motors with this pump ? What about the variable speed motor ? is this going to save energy ? Is there any configuration i need to change on the pump itself ? The motor installed was 1 HP, 1.25 SF, 7 - 168452 - 04, 230/115 V, 7.1/14.2 Amps. I am not looking to satay with the same motor but replace for something better that works with he existing pump. dual or variable speed. changing kit ?

Hi, Gon. Your single speed options are the Century B2853 or the Pureline PL2853. As for a variable speed, you can use the V-Green - ECM16SQU. You will also to get the Challenger CH Series Tune Up Kit - GOKIT5.

I'm looking for an O-Ring seal for this pump. It is leaking where the clamp holds it together. I'm assuming the O-Ring is broken. I haven't opened it up yet. I need a model number for the O-Ring.

With out knowing if it is just the housing gasket oring or the shaft seal. We would recommend Tune Up Kit Pentair Challenger Pump (CH Series) - GOKIT5

We have pool pump part number 342854, says discontinued! Replacement showing part number 343233! Our motor is new, can you buy the pump separate from the motor and will our motor adapt to the new pump. Or do we have to buy the pump and motor together??

A  Answered on 4/3/2017 by InyoPools Product Specialist Lennox H.

Hi, Kenneth. Pump housings are not available without the motor, you would have to purchase each part that makes up the pump separately which will total more than a new pump.

I currently have the model 343233. It is 15 years old and running fine, but it seems to be getting a little louder, but there is no screeching. It runs 16 hrs/day 5 months/year. Would you recommend replacing, and if yes, with the same model or is there a more efficient and quieter model you would recommend. This pump has been trouble free and I would like that to continue. Very pleased so far...Thank you.

A  Answered on 4/3/2017 by InyoPools Product Specialist Lennox H.

Hi, Wayne. With the pump being 15 years old I would recommend replacing it. There is not an energy efficient option as a complete pump, but you do have the option of replacing just the motor on your existing pump with the B841 Full Rate EE motor along with the seals.

I noticed that the Pentair Challenger 34233 is not energy efficient. Is there another pump that you would recommend that is?

A  Answered on 9/16/2016 by InyoPools Product Specialist Stacey M.

Hello Roz, there is Pentair Challenger 1 HP 115/230V Energy Efficient Pump - 345205

So this challenge for one horse power pump comes with the hair and lint trap also

A  Answered on 9/8/2016 by InyoPools Product Specialist Scott W.

If you are referring to the pump basket that fits inside of the strainer pot then yes, it will come with the pump basket.

?     Asked on 7/10/2016 by Michele

Is this a complete pump? The picture shows a motor with the pump, does this pump come with the motor? Also, is there an energy efficient direct replacement for this pump? I currently have a Pentair Pinnacle 342854 with a Century motor (B2853). The pump has a leak and the motor has a bad bearing. Just want to make sure I am replacing with compatible parts that are energy efficient and won't break the bank. If I need any other parts please list them in the reply. Thank you.

A  Answered on 7/14/2016 by InyoPools Product Specialist Lennox H.

Hi Michele, This is a complete pump which includes the motor and the pump housing. There is not an energy efficient model to this particular Challenger pump, you can go with a dual or variable speed pump if energy savings is your top priority. If you get this pump you will not need any other parts just pvc pipe and connectors for installation.
