The Preva 25 self-priming pool pump is equipped with a large-capacity pre-filter, and each manufactured unit undergoes individual testing – each pump comes with a recorded „birth certificate“ listing the measured technical values, inserted on the back of the manual.
Design and materials
- the pump body and diffuser made of glass-fibre-reinforced polypropylene ensure above-standard service life

- unique conical sealing system of the pre-filter lid
- sealing segment made of carbon-ceramic and AISI 316 stainless steel mounted in the impeller on a bronze insert
- the pump axis does not come into contact with the pumped water
- motor bearings with lifetime lubrication for long service life and quiet operation
