Variable Displacement Truck Pump lowers heat, fuel consumption.
November 20, 2009 -
Rated for continuous operation at pressures to 6,090 psi, 95 cc/rev VP1-095 suits mobile applications where power and precise control of multiple functions is required. IT can be mounted directly to truck PTO and supplies hydraulic system with precise amount of oil required to improve performance and control. Variable flow capability (up to 52 gpm) reduces heat generation, possibly eliminating need for oil cooler, while 11-piston design minimizes noise and pulsation levels.

Parker Releases VP1-095 Truck Pump in North America; Benefits Mobile Applications with Less Heat Generation for Lower Fuel Consumption, Longer Pump Life
MARYSVILLE, OH - The 95cc/rev VP1 Series truck pump from Parker Hannifin, the global leader in motion and control technologies, is ideal for mobile applications where power and precise control of multiple functions is required. Built to meet the needs of today's high-pressure systems such as those used on cargo cranes, the variable displacement pump is likewise suited for forestry equipment, sewage trucks and road maintenance vehicles such as snowplows and salt spreaders.
The compact-design VP1-095, which can be mounted directly to a truck PTO, supplies the hydraulic system with exactly the right amount of oil needed to improve performance and control. Thanks to the pump's variable flow capability, heat generation is significantly reduced. This can eliminate the need - and expense - of an oil cooler while reducing fuel consumption at the same time.
The 95cc displacement is an expansion of the VP1 family that includes 45, 75 and 120cc frames. Rated for continuous operation at pressures up to 6,090 psi (420 bar), the VP1-095 offers a variable flow up to 52 gallons-per-minute. The ground-up design of the VP1-095 allowed Parker to produce a pump rated higher than other pumps in the family (VP1-045, VP1-075 = 5,800 psi/400 bar; VP1-120 = 5,075 psi/350 bar) and weighing 2.2 lbs. less than the 75cc pump.
Field tests comparing Parker's VP1 Series pumps to fixed displacement pumps show substantial efficiency gains. Operating on a heavy-duty cargo crane, heat loss varied between 60-65% using fixed displacement pumps. The variable displacement Parker pumps reduced these figures to 25-30%, or less than half. Besides fuel savings, the lower temperature strain contributes to longer pump life and decreased maintenance costs. Furthermore, fewer exhaust emissions may contribute to a cleaner environment.
Parker's VP1-095, ideal for all load-sensing valve systems, also has the potential to increase mobile equipment productivity by delivering smooth system operation due to its highly responsive pilot assembly. The pump's 11-piston design contributes to low noise and pulsation levels, thus reducing the potential need for, and expense of, sound insulation while helping customers comply with OSHA hearing conservation/operator exposure standards.
