Parker hydraulic variable displacement truck pump series vP1 is an axial piston pump featuring high self-priming speed and high efficiency and is one of the leading truck pumps in the market. The Parker VP1 pumpcan be close-coupled to a gearbox PTo(power take-off) or to a coupling independent PTo (e.g.an engine PTo)which meets lso standard 7653-1985.VP1 Pumps provide circuit reliability at speeds up to 3000 rpm and 420bar (6,100 PSI).
An application that makes full use of all the features of the VP1 is truck cranes with a load sensing system.Thecomplex systems of refuse collection vehicles and sewage trucks as well as various combinations of tippers,cranes,snow ploughs, and salt/sand spreaders can also be greatly simplified and optimized with the VP1pump. The VP1 provides the hydraulic system with the correct amount of fluid at precisely the right moment,effectively reducing energy consumption and heat generation.This means a smoother and quieter hydraulicsystem with much reduced impact on the environment. The VP1 variable displacement pump is a very efficientand straight forward pump design with unsurpassed reliability.Its small envelope size gives a simple andinexpensive installation.
