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.

摘要： A leak detector for a pump having a plurality of stacked diaphragms includes a plurality of flat spacer rings each having discontinuous channels and being disposed in face-to-face abutting and stacked relationship with one another wherein the discontinuous channels of the spacer rings together form tortuous leak paths extending through the flat spacer rings from working areas of the pump to a point outside of sealing areas thereof. A port is disposed in fluid communication with the port and an apparatus is provided for developing a visual indication of fluid in the port. A circumferential fluid-tight seal is disposed radially outside of the port for sealing off fluid loss beyond the outer periphery of the plurality of diaphragms and flat spacer rings.

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 method of calibrating a lost-motion metering pump is disclosed wherein the pump includes a relief port, a movable hollow plunger having a bypass hole which is aligned with the relief port when the plunger is moved to an aligned position and a control rod extending into the hollow plunger. According to one aspect, the method includes the steps of moving the plunger to the aligned position, inserting a gage pin through the relief port and the bypass hole into the plunger, moving the control rod into engagement with the gage pin and fixing the position of the control rod.
