Diffuser for Micro Delfino 25, 33 and 50 pumps

The diffuser surrounds the impeller and directs water through the hydraulic section of the pump. Correct alignment and seal seating are essential.

Pool technician’s advice

Check the shape, impeller connection and diffuser seal at position 60. Micro and Mini use separately listed parts.

What to check before ordering

The diffuser works alongside the impeller to guide water through the hydraulic section. Damage or incorrect seating can affect the assembly. Distinguish physical damage from dirt or debris before ordering.

How to choose the correct version

Match the specified output group and original diffuser shape. Compare the centre opening, locating features and gasket seat. A diffuser for another impeller may not fit even within the same pump range.

When to replace the part

Replace it if cracked, distorted or damaged internally. Check the diffuser seal and remove debris during servicing.

Important points when replacing the part

Clean the seating surfaces and inspect the associated gasket when replacing the diffuser. Assemble without force and follow the pump instructions. Check correct positioning and fill the hydraulic section with water before starting.

Version details

Disconnect the pump from the power supply and drain the water before disassembly. Motor repairs, capacitor replacement and mechanical seal installation should be carried out by a qualified technician.

Using the exploded diagram

The listed position refers to the corresponding assembly diagram. The arrow helps locate the part; for some small components it marks only the fitting area. Compare the original part, its code and the specific pump version before ordering. You are ordering the item named in this listing, not the complete assembly in the diagram.
