Self-priming water pump with 4 valves

Can run dry without damage. Vibration-free, very quiet. Internal bypass to protect the pump from excessive inlet pressure. Permanent magnet motor with self-lubricating shaft. The 4-valve system avoids the characteristic pulsations of other autoclaves, when the tap is half-open. Complete with four fittings, two 1/2" threaded + two 14 mm with 1/2" hose nozzles, and a suction filter. Both the fittings and the filter snap into place. Automatic pressure switch.
