Designed for open circuit applications, the POOCCA Parker P1 PD piston pumps offer a variable displacement axial piston pump designed to excel in environments requiring continuous operating pressures up to 4,060 psi. The Parker pumps are engineered to deliver consistent, reliable performance and are supported by a rugged bearing design that ensures durability under varying operating conditions.
One of the standout features of the P1 PD series is its optional torque limiter, which not only increases productivity but also improves operational safety by preventing overload conditions. This capability is especially valuable in industrial and mobile applications where precise control and reliability are critical. The โbellows chamberโ technology also significantly reduces pressure pulsation and noise levels, optimizing operator comfort and efficiency.
The compact design of the P1 and PD piston pumps highlights their suitability for installations with limited space without compromising performance. Its high efficiency and noise reduction technology make it an ideal choice for applications seeking to increase productivity while maintaining a quieter operating environment.
