摘要： A reciprocating pump includes: a housing with a fluid channel that includes a pump chamber; a reciprocated member that is disposed in the housing to form the pump chamber, and reciprocable for suction and discharge of fluid; an actuator configured to reciprocate the reciprocated member; and a pressure gauge with a pressure receiving portion, configured to detect pressure of the fluid in the fluid channel via the pressure receiving portion. The housing includes an inner wall facing the fluid channel, and a flexible, membranous portion placed continuously next to the inner wall to face the fluid channel. The pressure gauge is attached to the housing such that the membranous portion is sandwiched between the pressure receiving portion and the fluid channel.

摘要： A reciprocating pump includes: a housing with a suction port and a discharge port; a reciprocated member disposed in the housing to form a pump chamber and reciprocable such that fluid is sucked into the pump chamber through the suction port and then discharged from the pump chamber through the discharge port; an actuator configured to reciprocate the reciprocated member; and a pressure gauge with a pressure receiving portion, configured to detect pressure of the fluid in the pump chamber through the pressure receiving portion, and coupled to the reciprocated member to be reciprocated by the actuator integrally with the reciprocated member.
