3. Main Features

Low-noise design for industrial environments
High-pressure performance up to 21 MPa
Modular cartridge kit structure for easy maintenance
High volumetric efficiency for energy saving
Compatible with mineral and synthetic hydraulic oils
SP version with shaft seal protection for improved durability

4. Typical Applications

Main/auxiliary pump for small- and medium-sized injection molding machines
Hydraulic systems for die-casting machines and presses
Hydraulic power units for CNC machine tools
Auxiliary hydraulic circuits for construction machinery
Power supply for automated production line hydraulics

5. Installation & Maintenance

Keep flange surfaces clean; tighten bolts evenly to avoid distortion
Coupling coaxiality ≤ 0.1 mm, angular error ≤ 1°
Suction line diameter ≥ pump inlet; avoid excessive length or bends
Prime the pump with oil before initial startup to prevent dry running
Regularly replace filter elements (≈2000 hours) and hydraulic oil (≈5000 hours)
Maintain oil cleanliness (NAS 10 or better)
Rotate shaft manually before restart after long-term storage

6. Ordering & Replacement

Standard replacement: PV2R1-17-F-RAA-42
Cartridge repair kit: PV2R1-17-KIT
Always confirm shaft type, mounting and rotation when ordering
