Catalog excerpts

DR Series Variable Displacement Piston Pump Feature : 1. Compact and light weight. 2. Quiet opeartion,even in high pressure range, with minimum vibration. 3. Aluminum casting body 4. Precision characteristics and prompt response. 5. Sturdy structure for high efficiency and long service lifetime. 6. More options of compensators than before . Technical Data Remark: Whenever setting pressure, please make sure the full cut-off pressure never exceeds the maximum intermittent pressure. A0: Standard Pressure Compensator HA: Load-Sensing Compensator GA: Remote controlled Pressure compensator GJ: Remote Pressure compensator with Proportional Pressure Control GR: Remote Pressure compensator with Electronic Unloading control GB: Remote Pressure compensator with Electronic 2 stage Pressure Control GC: Remote Pressure compensaotr with 2 stage Pressure + Electrical Unloading control GM: Remote Pressure Compensator with NG6 interface Remark: For detail of compensator, please contact with us. Handling: 1. Hydraulic Fluids: Petroleum base oil with anti-wear additives hydraulic oil, or R&O type hydraulic oils equivalent to ISO VG-32 or 46. 2 。 The recommended viscosityrage is from 20 to 400 mm /S. Oil temperature range is within 0 to 60 C. Both of above have to be satisfied for the use of the above hydraulic oils. 2. Contamination: Pleaes maintain the contamination degree within NAS 10 grade. We strongly suggest to use suction line filter of at least 100 μm.
