Key Features & Benefits
- Long Bearing Life: Hydraulically unloaded shaft design significantly reduces wear, extending service life
- Low Operating Noise: Optimized vane movement ensures quiet operation, suitable for noise-sensitive environments
- Easy Maintenance: Replaceable pump cartridges allow for quick servicing without disassembling the entire housing, minimizing downtime
- High Efficiency: Advanced hydraulic balancing minimizes energy loss, ensuring optimal performance under various conditions
- Flexible Configuration: Pressure port positions can be chosen individually (Top, Bottom, Left, Right), and rotation direction can be clockwise or counterclockwise
- Compact Design: Ideal for space-constrained applications
- Double Pump Functionality: Two pump kits on one shaft provide separate oil outlets for complex systems while sharing a common suction port
Applications
- Industrial Machinery: Machine tools, plastic injection molding, and die-casting equipment
- Mobile Hydraulics: Marine steering systems and construction machinery
- Custom Hydraulic Systems: Double pumps enable separate circuits for multifunctional operations
Frequently Asked Questions
What is the maximum operating pressure for these PVV pump models?
All three models (PVV41, PVV51, PVV52) have a maximum operating pressure of 210 bar.
Are these pumps compatible with fluids other than mineral oil?
Yes, they are compatible with mineral oil-based hydraulic fluids (HLP type). When equipped with FKM seals (indicated by "V" in the model code), they can also handle phosphate ester fluids.
Can the pump cartridge be replaced separately?
Yes. The modular design allows the pump insert (rotor, vanes, stator ring, control plates) to be replaced by simply removing the cover, without disassembling the main housing.
What do the codes in the model number (e.g., "RA15UUMC") mean?
The model code provides key specifications: R = Clockwise rotation (L for counterclockwise), A = Cylindrical shaft (B for reinforced cylindrical, J for splined), 15 = SAE flange connection, UU = Pressure port positions (e.g., U=Bottom, D=Top, R=Right, L=Left), M = NBR seals (V for FKM), C = Flange design (e.g., SAE-C for frame sizes 4, 5, 41, 42, 51, 52, 54).
What is the speed range for these pumps?
These pumps are designed to operate effectively within a speed range of 600 to 2800 RPM.
How are double pumps configured?
Double pumps are formed by installing two pump kits on one shaft. The larger kit is always on the flange side. They share a common suction port but have separate pressure outlets.
What is the typical delivery time for these models?
Delivery times can vary. Some suppliers indicate short lead times for in-stock items, while others may have longer periods. It's advisable to check with authorized distributors for current availability.
Where can I find technical drawings or CAD files?
Technical documentation, including data sheets and CAD files, is typically available through the official REXROTH website or authorized distributors.
