Rotary Group , Iran

The LPVD rotary group is an axial piston pump with variable swashplate and low-pressure control Low Pressure Variable Displacement. Its main housing is produced via high-pressure die casting from A380 aluminum alloy with 320 MPa tensile strength. The cylinder block is designed from hardened 16MnCr5 steel with 9 axial pistons and a slipper pad mechanism. The control system utilizes a direct hydraulic valve with an adjustable pressure range of 20 to 80 bar. This pump withstands 160 bar continuous operating pressure and 200 bar peaks per ISO 1 class. Nominal flow reaches 60 liters per minute at 2500 RPM and maximum angle. Volumetric efficiency under rated conditions is 94% with 88% overall efficiency.

The control structure includes a spring-loaded pressure regulator with 100-millisecond response and an internal check valve. The lubrication system operates via splash from an internal sump with a 25-micron filter. The input shaft is made from surface-treated Ck35 steel with a standard spline pin connection. The hydraulic oil operating temperature range is defined between -10°C to +70°C. Generated noise level at nominal pressure and one-meter distance measures maximum 68 decibels. The housing is protected against corrosion by a hard anodized coating 20 microns thick. The design service life until first overhaul under light-duty conditions is 12,000 hours.You can order and buy Rotary Group from Iran by contacting us through whatsaap and email.
