Wenzhou Prance Hydraulic Equipment Co., Ltd.
Heavy Duty Hydraulic Piston Pump PVB
1.Long service life, a variety of control types, low noise, high efficiency , small volume, light weight, less energy consumption and compatible with all kinds of fluids .
2.It has found wide application both in industrial made mobile equipment.
3.It’s mounting dimensions are designed in two different international standard-metric and inch systems.
4.In order to meet special demands by customers, it also has a mixed mounting type with inch standard moutning, flange& shaft end and metric standard oil ports connection.
Detailed Description
Both fixed and variable displacement models make up this range of axial piston pumps. Their high performance ratings and efficiencies are achieved with a variety of hydraulic fluids. Fixed displacement models are noted for their volumetric and mechanical efficiencies.Variable displacement models can closely match pressure and/or flow demand with a control selected from:
1.Pressure compensator with orwithout a remote control facility.
2.Pressure compensator withadjustable displacement control.
3.Load sensing compensator.
4.Mechanical (lever) control.
5.Handwheel control
