Description

The Pentair 521514 is the Shurflo pump head for the IntellipH controller. It is the genuine Pentair replacement part.

What it is

IntellipH manages pool pH by feeding acid on a controlled schedule. The Shurflo pump head is the wet end that actually moves the chemical. This listing covers the head alone, not a complete controller.

When to replace it

Feed pump heads handle aggressive chemical continuously and wear from the inside out. If the controller is powering up and calling for a feed but the acid level in the tank is not dropping, the pump head is the natural place to look before suspecting the controller itself.
