Patent number: 4545507Abstract: A metering pump is disclosed and includes a unitary pumping assembly secured to a base so as to be removable from the base as a unit e.g. for cleaning. The pump is of the plunger type and includes at least one plunger mounted to reciprocate in a pump cylinder, and a rotary valve for controlling flow of liquid into and out of the cylinder under the effect of reciprocation of the plunger. A linear actuator and a rotary actuator are each permanently mounted on the base for actuating respectively the plunger and the rotary valve. The linear actuator can be coupled to the plunger by disengageable coupling means including interfitting but physically unconnected male and female formations. The rotary actuator is similarly disengageably coupled to the valve member by a key and slot coupling. The disengageable coupling means allow the pumping assembly to be removed as a unit from the base by simply releasing a securing screw or the like.Type: GrantFiled: September 23, 1982Date of Patent: October 8, 1985Assignee: Hibar Systems Ltd.Inventor: Heinz Barall
