Eaton Vickers PVH131 Hydraulic Pump

Eaton Vickers PVH131 Hydraulic Pump is designed for high-displacement variable flow applications requiring open-circuit hydraulic system performance. With the inline axial-piston construction, it has a displacement of 131.1 cm³/rev and works efficiently under high pressure in various industrial and mobile equipment applications. The pump offers a good combination of hydraulic performance with responsive control capabilities for machinery which works with variable loads.

The Eaton Vickers PVH131 adjusts the displacement depending on the hydraulic flow and pressure needs of the circuit. In the case of difficult work processes, it provides high hydraulic flow for driving actuators efficiently. With lower hydraulic demands, the pump allows reducing the displacement to avoid unnecessary oil displacement.

Possible applications could be construction equipment, material handling equipment, industrial presses, plastic processing machines, and heavy hydraulic power units. The pump may have different configurations to provide such features as pressure compensation, load sensing, etc. Depending on the needs of specific application, some models may have through-drive designs allowing to install additional pumps.

Proper oil condition is vital to pump operation. The operators need to ensure appropriate viscosity of hydraulic fluid, good filtration and proper operating temperatures. In addition, they need to ensure that there are no restrictions and leakage of air in the inlet line. Poor inlet conditions can lead to cavitation, abnormal sounds and early damage to the cylinder block, pistons, valve plate and bearings.

The signs of worn PVH131 include low flow rates, unstable pressure and slow response of the equipment. High oil temperature, vibration and leakage around the shaft or control assembly may also be the indications of a faulty pump. Nonetheless, one needs to examine the whole hydraulic system first, as the fault might appear due to poor functioning of filters, valves and wrong settings.

Rexton Hydraulic provides repairs and replacements of Eaton Vickers PVH131 hydraulic pumps for use in industrial and mobile machinery. We analyze the complete pump code and its current application to recommend the most appropriate solution. We also conduct the pump inspection and evaluation of its internal components.
