China Nachi Hydraulic Pump PVD-0B-20P-6G-4939A Piston Pump | Partsdic®

The PVD-0B-20P-6G-4939A pump is designed to provide hydraulic power through the conversion of mechanical energy into fluid pressure.

It features a compact and lightweight construction, making it suitable for applications where space is limited or weight restrictions apply. The pump is known for its high volumetric efficiency, ensuring minimal energy loss and optimized power transmission.

One of the key specifications of the Nachi PVD-0B-20P-6G-4939A is its displacement, which is 20 cc/rev. Displacement refers to the volume of fluid displaced by the pump's pistons in one revolution. In this case, the pump displaces 20 cubic centimeters of fluid per revolution. This displacement value determines the pump's output flow rate and is a critical parameter in hydraulic system design.

The pump operates with a maximum pressure rating of 280 bar, allowing it to generate significant hydraulic force. This pressure rating indicates the pump's capability to withstand and deliver fluid under high-pressure conditions. It ensures reliable performance and enables the pump to meet demanding application requirements.

The PVD-0B-20P-6G-4939A pump utilizes a six-piston design, where six pistons are arranged radially around a central drive shaft.

This configuration provides smooth and consistent fluid flow, minimizing pulsations and vibrations. The pistons are driven by the rotation of the drive shaft, creating reciprocating motion within the pump chamber, which results in fluid suction and discharge.

To maintain optimum operating conditions and prevent excessive heat build-up, the pump incorporates a cooling system. This feature allows the pump to sustain continuous operation without the risk of overheating, ensuring extended service life and enhanced reliability.

The PVD-0B-20P-6G-4939A pump is engineered for compatibility with various hydraulic fluids, including mineral oil-based fluids and synthetic fluids. This versatility allows it to be used in a wide range of applications across different industries.

In terms of installation and mounting options, the pump can be easily integrated into hydraulic systems using standard mounting interfaces. It offers flexibility in terms of orientation, allowing for vertical or horizontal mounting depending on the application requirements.
