ABSTRACT:
A high pressure plunger pump, in particular for forwarding water and water with additives, comprises a plurality of plungers 20 which are driven by a crankshaft journalled in a drive housing 10. The free ends of the plungers 20 are each guided in respective pump chambers 22 of an induction-discharge housing 12 which is connected to the drive housing 10. The induction-discharge housing 12 is a one piece housing of generally L-shaped cross-section. The pump chambers 22 are arranged in one limb of the L-shaped housing and communicate with an induction chamber 27 via spring biased inlet valves 27 provided in axial extensions of the pump chambers. A discharge chamber 31 extends through the other limb of the L-shaped housing and is fed from the pump chambers via outlet valves 29. Both the inlet and the outlet valves 25, 29 are secured in position by respective threaded plugs. The use of a one piece L-shaped housing brings a number of substantial benefits. The housing is particularly convenient to manufacture, is very stiff, allows a significant weight saving, can be conveniently attached to the drive housing and allows ready access to all components for servicing and repair purposes. In a preferred arrangement high and low pressure seal 23, 34 are associated with each of the plungers 20 and the low pressure seals are arranged in a scavenge circulation established by connection passages 32, 32' extending between the induction chamber 27 and chambers accommodating the low pressure seals 34.
