Model 1: PVV2-1X/040RJ15-DMB-K02
Product Overview
The PVV2-1X/040RJ15-DMB-K02 (Material No. R901143587) is a Bosch Rexroth PVV2 Series industrial fixed displacement vane pump. With a geometric displacement of 40 cm³/rev, a maximum operating pressure of 175 bar, and a maximum flow rate of 59 L/min, this pump is engineered for reliable performance in industrial open-circuit hydraulic systems.
The PVV2 Series features a double-eccentric stator ring design that provides hydraulic unloading of the drive shaft — with two pressure chambers opposite two suction chambers, the shaft transmits torque only, significantly extending bearing life. The PVV Series is renowned for its low noise, low pulsation, and high efficiency characteristics, making it an ideal choice for demanding industrial applications.
As a premium aftermarket alternative to original Bosch Rexroth hydraulic pumps, this product offers 100% direct interchangeability with identical mounting dimensions and performance specifications, requiring zero modification to existing systems.
Every unit undergoes 100% simulated duty cycle testing prior to shipment, guaranteeing performance reliability under actual working conditions.
Technical Specifications (Bulleted List)

Key Technical Advantages
1. Double-Eccentric Stator Design – Hydraulic Unloading & Extended Life
The PVV2 Series features a double-eccentric stator design with two opposed pressure chambers and two opposed suction chambers, providing hydraulic unloading of the drive shaft. The shaft transmits torque only — without radial hydraulic forces — significantly extending bearing service life.
2. Low Noise & Low Pulsation Operation
The PVV Series is renowned for its low noise and low pressure pulsation levels. Optimized vane and stator geometry effectively reduces operating noise and flow pulsation, providing a more comfortable working environment.
3. Cartridge Design – Fast Maintenance
The pump cartridge (comprising rotor, vanes, stator ring, and control plates) can be replaced without detaching the housing from the pump carrier. This significantly reduces maintenance downtime and lowers total lifecycle maintenance costs.
4. High Efficiency Operation
Vanes are partially unloaded during passage through the suction range — a wear-reducing feature that ensures high volumetric efficiency. Pump performance does not degrade significantly with wear over its service life.
5. Robust Cast Iron Housing
The spheroidal cast iron housing provides robust protection for internal precision components, ensuring long-term durability in harsh industrial environments.
Application Areas
The PVV2-1X/040RJ15-DMB-K02 fixed vane pump is widely deployed across the following applications:
Machine Tool Hydraulics
Industrial Automation Equipment
Injection Molding Machine Auxiliary Systems
Presses & Clamping Systems
Material Handling Equipment
Industrial Open-Circuit Hydraulic Systems
Expert Maintenance Tips
Pre-Start Priming: Prior to initial start-up, fill the pump housing with hydraulic fluid through the drain port to ensure adequate lubrication of internal components.
Fluid Cleanliness: Maintain system fluid cleanliness to ISO 4406 18/16/13 or better to maximize vane and cam ring service life.
Rotation Confirmation: Verify pump rotation direction matches system requirements before installation. This model is configured for clockwise rotation (viewed from shaft end).
Cartridge Replacement: The PVV2 Series supports cartridge replacement without removing the pump housing from the mounting bracket. Simply remove the cover plate to access and replace the pump insert.
Mounting Torque: For SAE-B flange mounting, refer to Rexroth Service Manual (RE 10571) for specified torque values.
Speed Range Control: This model has a speed range of 600 – 1,800 RPM. Operation outside this range may cause cavitation or premature bearing failure.
