Rexroth Type PVV Series Heavy-Duty Industrial Fixed Vane Pumps

Product Overview: The Rexroth Type PVV Series fixed displacement vane pump is synonymous with stability and low-noise operation in global industrial automation and heavy machinery. As a classic Rexroth industrial power source, the PVV series is engineered for medium-to-high pressure, high-flow, and continuous heavy-load operation. This selection features core specifications: PVV21-1X/055-036RA15 (Part No. 901004734) — a double pump delivering efficient dual-circuit power, and PVV4-1X/082RJ15UMC (Part No. R901024704) — a robust high-pressure single pump. Utilizing a hydraulically balanced core, the PVV series maintains maximum volumetric efficiency even at pressures up to 21.0 MPa (210 Bar).

Key Technical Advantages:

• Efficient Dual-Circuit Control (PVV21): The double pump architecture allows two displacement cartridges (e.g., 55 and 36 cm³/rev) on a single shaft, ideal for independent high-low pressure synergy and energy optimization.

• Ultimate Quiet & Low Pulsation: Acoustically optimized stator curves effectively suppress flow pulsations, keeping operational decibels far below comparable gear pumps—ideal for improving workshop environments.

• Modular “Drop-in” Cartridge Maintenance: The internal pump core is a self-contained unit. Maintenance is streamlined—swap the internal cartridge on-site without disconnecting heavy plumbing, drastically cutting downtime.

• Heavy-Duty Longevity: Rated for pressures up to 210 Bar. The hydraulically balanced rotor design neutralizes radial loads, ensuring extreme bearing reliability under continuous heavy-duty cycles.

• Target Applications: Large-scale injection molding machines, metal shears, brick presses, rubber machinery, and heavy industrial Hydraulic Power Units (HPU).
