The pump body and diffuser made of glass-fiber reinforced polypropylene extend the service life beyond the standard. Transparent polycarbonate cover for easy inspection of the pre-filter. Unique conical sealing system for the filter cover. Two connection options - 1 1/2" internal thread or detachable connection with a D 50 mm adhesive protrusion. The sealing segment made of carbon ceramic and AISI 316 stainless steel is located in the turbine in a bronze inner coating. The pump shaft is not in contact with the pumped water. Motor bearings with lifetime lubrication for long service life and quiet operation. Lower engine starting temperature.
Two types of engines – 0.5 HP for model 25, 33, 50 and 1 HP for model 75 and 100 (input power is determined by turbine capacity). Preva pumps can be used for salt and sea water.
