Abstract
An apparatus for high pressure pumping or homogenizing of liquids has a drive motor with a transmission mechanism and a pump section. The transmission mechanism includes a belt train, a gearbox and a crank mechanism which is housed in a crankcase. The pump section includes a pump block, valves, and pistons which are connected to the crank mechanism. The transmission mechanism converts the rotary movement of the drive motor into the reciprocating movement of the pump pistons. The drive motor is placed directly above the crankcase and is surrounded on two sides by partitions which are interconnected by a roof. The partitions form, together with the roof, an air channel such that the driving parts of the apparatus may be cooled in a simple and efficient manner. By use of various arrangements peripheral to the apparatus, the air may be led off or recycled after cooling and recovery of the heat.
