Abstract (en)
A fluid dispensing piston pump (10) that is adapted to be cleaned in place without disassembly of the pump. During the cleaning operation the piston (22) of the pump is positioned in an area (30) of larger diameter at the base of a cylinder (20) such that the seal between the piston face and cylinder is broken. Seals (42) are provided for closing the upper end of the cylinder thereby allowing steam or a cleaning fluid which is introduced through the inlet check valve (18) to fill the cylinder and sterilize the piston face (34) and stem members (35). Steam is then discharged through a outlet check valve (24).
