RP Series Variable Displacement Rotor Pump

SKU: RP Series Variable Displacement Rotor Pump

The RP Series Rotor Pump is a variable displacement vane-type pump specifically engineered for low-noise and high-efficiency industrial applications. Utilizing a unique cam ring design, the RP series eliminates the need for complex swashplates, resulting in a compact and durable unit. It is the industry standard for CNC machine tools, hydraulic clamping systems, and lubrication units where energy saving and quiet operation are paramount.

Key Features:

Series: RP (Rotor Pump)
Sizes: RP08 to RP38
Max. Pressure: Up to 140 bar (14 MPa)
Design: Variable Displacement, Low Pulse.

Product Overview The RP Series (commonly associated with the Daikin design) represents a significant advancement in variable displacement pump technology. Unlike standard vane pumps, the Rotor Pump minimizes friction and internal leakage through its simplified internal structure. It automatically adjusts flow output based on system pressure demands, ensuring minimal heat generation and reduced power consumption during holding cycles.

Why Choose the RP Series?

Whisper Quiet: The operational noise level is significantly lower than standard gear or piston pumps, making it ideal for indoor factory environments.
Energy Efficient: The variable displacement mechanism reduces the electric motor load during pressure-holding phases (deadhead), saving up to 40% energy compared to fixed pumps.
Reliability: Simple construction with fewer moving parts reduces wear and maintenance requirements.
Compact Design: The direct-coupled motor options and small footprint allow for easy integration into compact hydraulic power packs (HPU).

Common Applications:

Machine Tools: CNC Lathes, Machining Centers (Clamping/Unclamping).
Industrial Machinery: Small Presses, Shears.
Automation: Transfer lines, Robotics hydraulics.
Lubrication Systems: Continuous oil supply.
