Rexroth Type PVV Vane Pump | PVV1-1X/046, PVV21-1X/045-036 | 210 Bar

Rexroth Type PVV Series Heavy-Duty Industrial Fixed Vane Pumps

Product Overview: The Rexroth Type PVV Series fixed displacement vane pump is the global industry standard for reliability and silent operation in industrial automation and heavy machinery. Designed specifically for medium-to-high pressure and continuous heavy-load operation, the PVV series is a powerhouse of the Rexroth industrial lineup. This selection features core specifications: PVV1-1X/046RA15UMB (High-efficiency single pump) and PVV21-1X/045-036RA15UUMB (Precision double pump). Utilizing a hydraulically balanced core, the PVV series maintains maximum volumetric efficiency and significantly reduces system noise even at continuous operating pressures up to 21.0 MPa (210 Bar).

Key Technical Advantages:

• Efficient Dual-Circuit Control (PVV21): The double pump architecture allows two different displacement cartridges (e.g., 45 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: CNC machine tools, large-scale injection molding machines, brick presses, rubber machinery, and industrial Hydraulic Power Units (HPU).
