Quick overview

  • Original manufacturer equipment Pentair part 354531Z, the factory lid rather than an aftermarket copy.
  • Dynamo strainer pot The clear lid over the basket on the Pentair Dynamo pump.
  • Where prime is won or lost The lid and its O-ring form part of the suction side seal, so a cracked lid means a pump that will not hold prime.
  • Generic alternative exists A third party Dynamo lid is available separately if budget matters more than OEM.
  • Lid only The lid O-ring is a separate part and is worth replacing at the same time.
  • Handles are the weak point Overtightening and years of sun leave the lid crazed and brittle, and that is when it starts leaking air.

Product details

The Pentair 354531Z is the strainer pot lid for the Dynamo pool pump. It is original manufacturer equipment, the same lid the pump was built with.

Why the lid matters

While the pump runs, everything on the suction side is under vacuum, and that includes the strainer pot. The lid seals the top of it. A lid that is crazed, cracked or warped enough that it will not sit flat lets air past, and the pump loses prime, runs with air in the pot, or never primes properly to begin with. Owners usually go looking for a suction line leak long before they suspect the lid.

What is included

The lid alone. The lid O-ring is a separate part and should be replaced at the same time, since the old one has taken the shape of the old lid. A generic Dynamo lid from a third party manufacturer is available if you would rather not pay for the OEM part.

Questions and answers

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

Does the O-ring come with the lid?
No. The Dynamo lid O-ring is a separate Pentair part, and it is worth replacing at the same time as the lid.
Is this the genuine Pentair lid?
Yes. It is original manufacturer equipment, part 354531Z. A generic Dynamo lid from a third party manufacturer is also available separately.
Why does a cracked lid stop the pump priming?
The strainer pot is under suction while the pump runs. Any crack or a lid that will not seat lets air in, and the pump loses prime instead of pulling water.
What else is available for the strainer pot?
The pot O-ring, the trap basket housing and the Dynamo basket with handle are all separate parts.
