3.2 V Series Double Pumps
Combined by two single V-series pumps, model format: 2520V/3520V/3525V/4525V etc. (e.g., 4535V50A25-1AA22R). Key specifications are consistent with single V-series pumps, with max pressure up to 17 MPa and max speed 1800 rpm. Suitable for industrial systems requiring dual independent hydraulic circuits.
4. Core Features
-
Balanced Vane Design: Diametrically opposed inlet/outlet chambers balance radial loads, extending bearing life.
-
High Performance: Volumetric efficiency >90%, noise level as low as 62 dB(A), suitable for high-pressure operation.
-
Versatility: Compatible with petroleum-based oil and synthetic fire-resistant fluids; reversible rotation via internal part adjustment.
-
Compact Structure: Double pumps integrate two units in one housing, reducing installation space and simplifying drive system.
5. Applications
Industrial presses, aerial booms, plastic injection molding machines, material handling equipment, heavy-duty trucks, and complex hydraulic power units.
