Intelligent Monitoring: NSD10F001D module provides real-time feedback on temperature, pressure, and vibration, compatible with remote control systems.

Easy Integration: ISO-standard 32R flange, right-hand rotation, multi-pump parallel capability, and direct interchangeability with imported A4VG models.

Noise Reduction: Low operating noise at 53dB, creating a quieter working environment.

Model Definition

The model code A4VG250HD3DT1/32R-NSD10F001D has a professional and clear coding logic, which is convenient for purchasers to quickly identify product performance and application scenarios, and is completely different from the model interpretation of A22V, A20VLO, A4VS0 series and other previous series. The specific interpretation is as follows:

A4VG: Inclined-axis compound variable plunger pump series (core identifier, distinguishing from A22V swashplate electro-hydraulic proportional variable, A20VLO inclined-axis load-sensitive variable, A4VS0 swashplate constant power variable and vane/gear pumps);

250: Rated displacement of 250 cm³/rev, focusing on heavy-duty large-flow output, which is 5.6 times that of the A22V series core model, 1.3 times that of the A20VLO series core model, and the same as the A4VS0 series core model, but more optimized for heavy-duty impact resistance;

HD3DT1: Compound variable (constant power + load-sensitive) + high-temperature and high-vibration adaptation, the core technical highlight of this model, realizing intelligent matching of load and power, and adapting to high-temperature (up to 120℃) and high-vibration working conditions;

32R: Large-specification flange connection (conforming to ISO 3019/3), right-hand rotation installation, suitable for large-scale heavy-duty equipment with high installation strength requirements;

NSD10F001D: Integrated intelligent monitoring module + 10V signal feedback, supporting real-time monitoring of pump body temperature, pressure and vibration parameters, and compatible with remote control systems for harsh working scenarios such as underground mines. 

As the core model of the A4VG series, Plunger Pump A4VG Series A4VG250HD3DT1/32R-NSD10F001D is specially optimized for heavy-duty, high-vibration and high-temperature harsh environments, with outstanding compound variable performance and anti-vibration capability, and is widely used in global mining, port, and heavy-duty engineering fields.
