Pump diffuser

Pump diffuser: restore your pump's performance

The diffuser is the internal part that channels water to the impeller and optimises discharge pressure. Worn or cracked, it drops the flow rate and the pump's efficiency. Replacing it gives your pump back its full power, for a fraction of the cost of a new one.

Our range of pump diffusers

• Original diffusers: they match the exact shape specified by your pump's manufacturer.
• Adaptable diffusers: they replace the part on the most common pump models.
• Diffuser gaskets: they ensure the seal between the diffuser and the pump body.
• Diffuser and impeller kits: they renew both linked wear parts at once.
• Multi-brand references: they cover a wide range of pumps on the market.

How to choose your pump diffuser

• Note the exact brand and model of your pump.
• Compare the shape and diameter with your original part.
• Change the gasket and, if needed, the impeller at the same time.

The Piscine-SAV technical tip: a diffuser is best changed together with the impeller, as both parts wear together. If unsure about the reference, send us a photo of your dismantled pump and we will check for you.

Our experts identify the diffuser that fits your pump exactly. Fast Europe-wide delivery and secure payment to extend the life of your equipment without replacing it.
