Yuken Type PV2R Double Vane Pump | PV2R33, PV2R34 | 200, 237, 153 Series

Yuken Type PV2R Series High-Performance Double Vane Pumps

Product Overview: The PV2R Series Double Vane Pump is the definitive power core for achieving high-efficiency control in complex hydraulic circuits. By integrating two independent pump cartridges on a single drive shaft, this series delivers two isolated oil flows, widely used for high-low pressure switching logic (Rapid-to-Working Feed). This featured range highlights premium double-pump specifications: the high-flow S-PV2R34-66-200-F-RFLA-35, the mid-range PV2R33 series, and the heavy-duty PV2R34 configurations. Utilizing a unique low-noise balanced structure, PV2R double pumps maintain exceptionally low pulsation and operational decibels even under full load.

Key Technical Advantages:

• Efficient Dual-Output Combination: A single motor drives two cartridges with vastly different displacements (e.g., the PV2R34 integrating 66ml with 200ml or 237ml), simplifying plumbing and optimizing machine footprint.

• Ultimate Silence & Stability: Precision-ground stator curves and 12-vane rotor designs ensure noise levels stay significantly below industry standards, even during dual-circuit high-pressure operation.

• Modular Cartridge Design: Internal pump cores are independent modules. Maintenance is streamlined—swap the cartridge kits without disconnecting main piping to restore factory performance and minimize downtime.

• High Volumetric Efficiency: Automatic side-plate clearance compensation ensures high output precision during long-term heavy-duty cycles, reducing system heat and energy loss.

• Target Applications: Large plastic injection molding machines, rubber vulcanizing machinery, scrap metal balers, concrete machinery, and customized industrial Hydraulic Power Units (HPU).
