Quick overview

  • Commercial duty The C-Series is built for large pools, fountains and water features that run continuously.
  • Bronze construction A bronze body is what lets this pump live in commercial and indoor installations for years.
  • Stainless steel strainer basket The strainer is part of the pump, not a bolt on, and the basket is stainless rather than plastic.
  • Three phase, 220-440V Wired for commercial power, so confirm your service before ordering.
  • 5 horsepower Sized for the high flow rates large bodies of water and water attractions demand.
  • Medium and high head performance The C-Series line is specified where head pressure, not just flow, is the problem to solve.

Product details

The Pentair C-Series CHK-50, part 011657, is a 5 horsepower commercial pool pump in bronze, wired for three phase power at 220-440V and supplied with an integral strainer.

Where it belongs

This is a heavy duty commercial pump for large pools, fountains and water attractions, the kind of installation that asks for high flow and does not get to stop. The C-Series has held the standard for medium and high head performance in the pool industry for a long time, which is why it keeps turning up on commercial specifications.

Built for continuous duty

The bronze body and the stainless steel strainer basket are the reason it lasts. Both indoor and outdoor projects are hard on equipment in different ways, and this construction handles either. Maintenance is straightforward and the pump runs quietly for its size.

Before you order

Confirm you have three phase service in the 220-440V range and that the plumbing matches. This pump ships freight because of its weight.

Questions and answers

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

What kind of pool is this pump for?
Commercial water: large pools, fountains and water attractions that need high flow and run continuously. It is not a residential backyard pump.
What electrical service does it need?
Three phase power at 220-440V. Single phase service will not run it, so have the panel checked before you buy.
Does it come with a strainer?
Yes. The strainer is part of the pump and the basket is stainless steel.
Why bronze instead of plastic?
Bronze holds up to continuous commercial duty and to indoor installations where a pump may run year round. It is the reason the C-Series stays in service as long as it does.
