Why Choose Hengmeisi's Plunger Pump A20VLO Series A20VLO190DRS/10R/10L-NZD24N00?

Heavy-Duty Inclined-Axis Structure

Unlike ordinary gear pumps or vane pumps, this Plunger Pump A20VLO Series A20VLO190DRS/10R/10L-NZD24N00 adopts an inclined-axis variable plunger structure for stronger load capacity and smoother oil delivery.

Key Benefits

Supports large-flow hydraulic systems with 190 cm³/rev displacement

Excellent resistance to vibration and impact conditions

Stable continuous operation under heavy-duty workloads

Suitable for long-hour industrial operation environments

Intelligent Load-Sensitive Variable Control

The DRS electro-hydraulic proportional control system automatically adjusts displacement according to actual load demand.

Advantages for Users

Reduces unnecessary energy consumption

Improves hydraulic system efficiency

Enhances response speed during changing loads

Helps lower long-term operating costs

Model Code

The model code A20VLO190DRS/10R/10L-NZD24N00 has a clear and unique coding logic, which is easy for purchasers to quickly identify product parameters without professional hydraulic knowledge, and is completely different from the model interpretation of the A22V series and other previous series. The specific interpretation is as follows:

A20VLO: Inclined-axis variable plunger pump series (core identifier, distinguishing from the swashplate A22V series and vane/gear pumps);

190: Rated displacement of 190 cm³/rev, focusing on large-flow output, which is 4 times that of the A22V series core model;

DRS: Electro-hydraulic proportional variable + load-sensitive control mode, realizing energy-saving adjustment according to actual working load;

10R/10L: Dual-direction installation design (right and left), compatible with different equipment installation spaces and pipeline layouts;

NZD24N00: Integrated low-temperature resistant sealing + 24V electromagnetic control configuration, adapting to low-temperature working environments and intelligent control needs.
