Parker Medium Pressure Mobile Pumps (P1 Series) are variable displacement medium pressure axial piston pumps designed for open-circuit mobile applications. These pumps are constructed in a compact size that makes them ideal in limited space conditions. P1 Series produces low noise level and reliable performance, which enables them to be suitable in various machines. Parker P1 piston pumps deliver a continuous operating pressure of up to 4,060 psi (280 bar).
Parker P1 Medium Pressure Piston Pumps are developed with a cradle-bearing design that increases productivity and improves the working environment. These pumps are available with a robust, wide temperature range, full power thru-drive capability, and an optional torque limiter. Concrete pumps, chemical pump trailers, backhoes, bulldozers, front loaders, and winches are some of the common applications where these pumps are utilized.
These pumps are featured with unique "ripple chamber" technology, which minimize pressure pulsations and decrease noise. With lower power consumption and reduced heat, the Parker P1 pump ensures reliable performance and efficient control. Additionally, Parker designs high-drive speed models for mobile markets and low-noise models for industrial markets.
