Characteristics. This series of gear pumps and motors available in the form of size 4. Flow rates up to 1081pm, maximum pressure 250bar. Multi-joint combination can be, with a series of meet SAE, DIN, European standard mandrels, flanges and access port assembly form. . After processing of high tensile aluminum alloy body and anti-extrusion die front and back covers, to ensure high volumetric efficiency, mechanical efficiency and low noise characteristics. . Viton seal material of the parts can withstand high temperatures of operation. . The special design of oil-free bearings operating under high pressure. . Can be forward, reverse, reversing. . Synchronous motor can be more joint combination, to achieve more with cylinder synchronization purposes. Synchronization accuracy of 95%, than the average 70% better shunt valve. Technical Note hydraulic oil used. Department of petroleum-based hydraulic fluid, specifications meet the ISO or din standards. Other oil, please contact us. Oil temperature and viscosity. Environmental viscosity range: -15 °C -80 °C (5 °F -176 °F). Viscosity range: 12cSt-800cSt. Recommended viscosity: 16cSt-40cSt. Filtration precision: Suction side-60um; pressure side -10% 25um. Installation and driver. Installation and drive gear pump, must avoid the force of radial or vertical. . Even the shaft deviation angle must be set aside and maintained at 0.8 mm (0.003 ") TIR pressure within the oil port. Into the oil port of the minimum allowable pressure of 0.7bar. Minimum speed. Each type of the minimum allowable pressure: HGP-05A 800 rpm HGP-1A 500 rpm HGP-2A 500 rpm HGP-3A 500 rpm If other applications or products, please contact the company. . Using oil exceed 60 °C 140 °F. Motor and gear pump assembly when the non-horizontal. . Self-change when turning or internal parts. Part of the special requirements of materials, such as oil seals, 0-ring or around the cover.
