摘要： A diaphragm metering pump includes a pump body having a head portion including a suction side and a discharge side defining a flow path. A valve seat is arranged at one of the suction side and the discharge side, and a check valve is arranged at the valve seat. A degassing system includes a check valve actuator operatively connected to the check valve. The check valve actuator is selectively activated to unseat the check valve from the valve seat to allow gases trapped in the head portion to pass through the discharge side.

摘要： A reciprocating pump assembly comprises: a motor with a rotary motor drive shaft; a cam coupled to the motor drive shaft with an axis of rotation and a cam channel cut generally axially into a radial face of the cam; and multiple reciprocating pump units arranged radially about the cam axis of rotation, each with an inlet valve, an outlet valve, a plunger and a plunger sleeve, with a free end of its plunger coupled to the cam by way of a cam follower riding in the cam channel; wherein rotation of the motor output drive shaft causes the plunger in each pump unit to independently reciprocate in its respective sleeve.
