Alternative to KCL DVQ20 Hydraulic Pump (210 bar) — Suitable for Medium-to-Low Pressure Hydraulic Systems
The DVQ20 is a single-stage internal vane pump designed for medium-to-high pressure applications. Featuring an internal vane design, it delivers a robust and constant pressure output, with a rated operating pressure typically set at 21 MPa. It is equipped with an automatic end-face clearance adjustment system that maintains a stable flow output across varying pressure levels.
الوصف
ميزة
The DVQ20 is a very efficient vane pump with a double-vane layout, mainly used for mobile machinery and construction equipment.
1. It uses a hydraulically balanced double-vane arrangement that significantly lowers pressure on the stator; its nominal pressure reaches 21 MPa, with a maximum pressure capability of 26 MPa.
2. The DVQ20 pump boasts a highly efficient layout which results in very quiet operation and hardly any output pulsation, thus greatly enhancing the working environment.
3. Thanks to the floating side plate arrangement, this pump automatically adjusts wear-related clearances so that even at high rotational speeds, it maintains high volumetric efficiency.
4. The side plates are made of a flexible bi-metallic material that is highly resistant to seizing, while major components are made from high-speed tool steel, which makes them highly resistant to contamination.

1. The DVQ20 hydraulic pump is used in refuse compactors, street sweepers, large and small forklifts and for small cranes due to its shock absorbing capabilities; high-pressure tolerance; and ability to endure frequent starting and stopping of operation, and is subjected to various weight loads in an outdoor environment.
2. The hydraulic power unit on plate shears, bending machines and CNC mills utilizes the DVQ20 due to the low flow pulsation of hydraulic actuators resulting in smooth, stable operation and increasing the precision of manufactured parts.
3. Bimetallic side plates, produced from high-speed tool steel, on the DVQ20 provide a reduction in wear life, longer operational life and the DVQ20 can still maintain high volumetric efficiencies due to small amounts of contamination within the hydraulic fluid.
4. The flexible design of the DVQ20 unit allows for many combinations of shaft end types (keyed, splined, etc.) and location of suction and discharge ports greatly affect the design of the unit by the OEM.
