FIELD: engines and pumps.
SUBSTANCE: device incorporates a protector made of a material allowing expansion and compression of internal fluid medium and making a barrier between fluid media outside the protector casing and internal fluid medium. The said casing has the first and second ends, with, at least, one of which coupling the protector with the pumping system other components. The said protector incorporates an assembly made up of, at least, two parts interconnected by a coupling appliance allowing a selective connection/disconnection of, at least, two parts.
EFFECT: higher reliability and longer life of the pumping system protection device attained by ease of purification and reuse of the said device.
