Front section (body) of ESPA Silen pump – old type (up to 2007)

The front section of the ESPA Silen pump (old type, manufactured up to 2007) is the suction part of the pump body that forms the basis of the hydraulics and holds the pre-filter basket with its transparent lid.

The older design differs from the new type (from 2007) in the geometry of the suction port and the shape of the seating surfaces, so the parts are not interchangeable.

A damaged front section (cracks, damaged threads, leaks around the suction port) causes air pockets in the hydraulics and a drop in pump flow.

Replacement brings the older pump back to a fully functional state without the need to purchase a completely new unit.

The original ESPA part for the old-generation Silen (up to 2007) guarantees precise compatibility with the other parts of the same generation.
