Abstract
A new and improved liquid metering pump for use in pumping sterile fluids and foodstuffs includes a separable autoclavable pump head assembly. The diaphragm-containing pump head may be preassembled as a unit and sterilized to provide a pump head having sterile product contact surfaces. The pre-sterilized pump head may be mounted and connected to an electronic solenoid metering pump and used for delivering fluids in food preparation, medical and pharmaceutical applications.
