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.

The compact, easily useable metering pump results from a structure including a housing (,) with a pumping chamber (,) within the housing (,). A diaphragm (,) is located in the pumping chamber (,). An inlet includes a check valve (,) for allowing fluid to flow to one side of the diaphragm (,) but not the reverse and an outlet including a check valve (,) allows fluid to flow from the pumping chamber (,) but not into it. A pneumatically operated hydraulic pump (,) is located in the housing (,) and cycles the diaphragm (,).

Metering pump

A streaming current detector has a reciprocating piston with a sensing region having a uniform clearance from the casing which is sufficiently large to avoid significant shearing of the particles in the fluid of the sample stream. A separate guiding region of the piston has a sufficiently tight fit in the casing for smooth reciprocation. A relief region of the piston has the largest clearance from the casing to provide a sufficiently large area to control a constant low velocity of the sample fluid.
