The Parker P2 and P3 are variable displacement, open-circuit axial piston pumps in swashplate design, developed for heavy-duty mobile hydraulic applications. Both series share the same housing and mounting interface, with displacements from 60 to 145 cc/rev and continuous operating pressures up to 320 bar.

The P2 is a self-priming standard version. The P3 adds a built-in impeller, achieving higher self-priming speeds for operation in high-altitude environments or systems with restricted inlet conditions. An integrated ripple chamber — standard on all side-ported units — reduces outlet pressure pulsation by 40-60%, significantly lowering system noise without additional components.

Parker P2/P3 Key Features

Direct PTO mount — Compact envelope and unique port layout designed for direct mounting on mobile transmission PTOs — no adapter brackets needed. Standard on most construction, forestry and material handling transmissions, significantly reducing installation cost and complexity.

Integrated ripple chamber — Reduces outlet pressure pulsation by 40-60% compared to a pump without this technology — standard on all side-ported units. Less ripple means quieter systems, longer hose life and reduced noise insulation requirements on the machine.

P3 built-in impeller — The P3 version adds an internal supercharge impeller, enabling higher self-priming speeds and reliable operation at altitudes up to 3,660 m (12,000 ft) or with restricted inlet conditions — common in forestry and mining equipment.

Multiple control options — Pressure compensator (PA), load sensing (LA/LB) and torque-limiting with load sensing (TA/TB/TC/TD) — all available as factory-fitted options. Torque control is particularly valuable when engine power is shared between hydraulics and drivetrain.

Through-drive capability — Accepts a second pump in tandem across all frame sizes, enabling compact dual-pump configurations for machines with separate implement and steering circuits.

Parker P2/P3 Applications

The P2/P3 series covers the most demanding mobile hydraulic markets.

Construction equipment — Wheel loaders, articulated dump trucks and surface drill rigs. Direct PTO mounting eliminates adapter costs; torque control (TA-TD) protects the engine during combined high-flow and high-pressure duty cycles.

Material handling — Reach stackers, heavy-lift trucks and all-terrain mobile cranes where high-pressure variable flow and a compact installation envelope are both required.

Forestry machinery — Forwarders and harvesters frequently operate at elevation or with long suction lines. The P3's built-in impeller maintains full flow output in these conditions.

Mining & drilling — Dump trucks and drill rigs in contaminated environments where robust design, long service intervals and reliable self-priming at any altitude matter.

Agriculture & municipal equipment — Harvesters, mowers and vocational vehicles benefiting from the compact envelope, load sensing control and low-noise ripple chamber technology.

Defense vehicles — Mobile equipment requiring reliable hydraulic power under extreme environmental and duty conditions, with flexible mounting options to suit diverse vehicle platforms.

Parker Axial Piston Variable Pumps Series P2/P3 Description

Parker piston pump P2 and pump P3, which are made in Germany, are variable, swashplate piston pumps designed for operation in open circuit, mobile hydraulic systems. Perfect choice when it comes to cost-saving installation as well as high productivity and power density. Displacements from 60 to 145 cc/rev., such as Parker piston pump P2060, P2075, P2105, P2145, P3105 and P3145.

Parker P2 and P3 pump has been designed to meet the specific demands of heavy duty mobile applications. By featuring an optimized envelope and a unique port layout the product line provides for a cost saving direct mount on most typical mobile transmissions. The availability of both a standard (Parker P2) and a supercharged, internally boosted version (Parker P3) allows for high flow operation at the most diverse inlet conditions. With continuous pressure ratings of up to 350 bar P2/P3 provides a high power density and enables downsizing of mobile machinery. As a standard every Parker P2/Parker P3 comes with an integrated pre-compression volume which ensures low ripple operation and reduced noise emissions.
