Abstract
A reciprocating pump (1) comprising a pumping chamber (30) and an intermediate chamber (40), a reciprocating member (50), high pressure seal means (21) between the pumping chamber (30) and the intermediate chamber (40), low pressure seal means (22) between the intermediate chamber (40) and the crankshaft housing (10), a pumping circuit (60) and an auxiliary circuit (70) in fluid separation from the pumping circuit (60). The pump further comprises a recirculating unit (80) whose inlet is connected to the delivery chamber (72) of the auxiliary circuit (70) and whose outlet is connected to the suction chamber (71) of the auxiliary circuit (70). The recirculating unit (80) comprises a recirculating pump (81) which is designed to suck fluid from the delivery chamber (72) and pump such fluid in the suction chamber (71) for fluid recirculating in the auxiliary circuit (70).
