Rexroth 1PV2V3 1PV2V4 1PV2V5 Vane Pump | 1PV2V3-30/40RA01MC25A1

The Rexroth 1PV2V Series from LIC Hydraulic is the premier solution for Low-Noise Variable Vane Pumps. Designed for open-circuit applications where quiet operation and energy efficiency are paramount, models like the 1PV2V3-30/40RA01MC25A1 provide automatic flow adjustment based on system pressure requirements. Whether it’s the 1PV2V3, 1PV2V4, or 1PV2V5 frame size, these pumps are engineered to deliver consistent performance in demanding factory environments. We provide 100% drop-in replacements, ensuring total mechanical compatibility with original Bosch Rexroth specifications for mounting, shafts, and ports.

Technical Highlights

• Series Groups: Size 3 ($12\text{–}40\text{ cc}$), Size 4 ($32\text{–}80\text{ cc}$), Size 5 ($63\text{–}125\text{ cc}$).

• Max Pressure: Continuous duty typically up to $100\text{–}160\text{ bar}$ (depending on configuration).

• Control Type: Integrated pressure compensator for energy-saving “deadhead” operation.

• Design: Direct-acting variable swashplate vane technology.

Core Advantages

• Superior Acoustic Performance: Vane pumps are inherently quieter than piston or gear pumps. The 1PV2V series minimizes hydraulic “hum,” making it ideal for indoor machinery and operator-intensive work cells.

• Efficient Energy Management: By automatically shifting to zero flow once the target pressure is reached, the 1PV2V pump significantly reduces heat generation in the reservoir, extending the life of the hydraulic oil and seals.

• Precision Pressure Control: The high-sensitivity compensator allows for fine-tuning of the system pressure, ensuring that auxiliary functions like clamping or lubrication are performed with repeatable accuracy.

• Robust Maintenance Profile: Simplified internal design with hardened components ensures high resistance to wear, leading to lower total cost of ownership (TCO) for MRO operations.

Expert Maintenance Tips

• Oil Viscosity is Key: Vane pumps rely on a thin oil film for vane extension. Ensure the hydraulic oil is within the recommended $20\text{–}100\text{ cSt}$ range. Oil that is too thick can cause the vanes to stick, leading to immediate efficiency loss.

• Rotation Check: Always verify the “R” (Clockwise) or “L” (Counter-clockwise) arrow on the nameplate. Running a 1PV2V pump in reverse will cause the internal components to seize and may damage the drive motor.

• System Bleeding: During initial installation, ensure all air is purged from the pump case. Air pockets in a vane pump can cause “chattering” and localized heat buildup, which can score the precision-ground stator ring.
