My current pump has a leak and is making a loud noise. Other than replacing the motor, is there anything else that I need to replace?
Hi Joe, for us to suggest the proper seal kit could you send a photo of a wide shot of your complete pool pump to show the pipes going in and out of the pump? To supply this photo simply click the reply link below and upload your photo or quickest using our live online chat feature. Once we get this photo we can make the proper recommendation for the seal kit.

What shaft seal and gasket set do I need for this motor? I have a Sta-Rite PLM150 pump.

Hello Sheryl. The Sta-Rite PLM 150 is a Cartridge Filter. The motor shaft seal and seal plate gasket are specific to the pump manufacturer/model and not the filter. Please provide manufacturer/model information or pictures of your current pump so a recommendation can be provided. If you are providing pictures, please be sure to send several that include the entire pump from inlet to out piping.

Can you recommend a seal kit for: Century (A.O. Smith) 1.65 HP Up Rate Motor, Square Flange 48Y Frame, Single Speed - Model HSQ165. Pics attached.
Hello, we do not have a pre-assembled seal kit for your pump model, but I can recommend the individual components for your pump that would constitute the seal kit.Trap Lid O-RingDiffuser O-ringPump Shaft Seal AssemblyFaceplate GasketLubricant
