Product Introduction
ATUS A10VG Series Swash Plate Axial Piston Variable Pump is specially designed for hydrostatic closed-circuit transmission. Equipped with an integrated charge pump and built-in high-pressure relief valves, it supports stepless displacement adjustment from zero to maximum. It can smoothly reverse flow direction when passing the neutral position. Multiple displacement sizes and diversified control options are available for direct replacement of mobile machinery closed drive systems.

Features
Swash plate axial piston structure for closed hydraulic circuit
Infinitely variable displacement, flow adjustable from 0 to full displacement
Smooth flow reversal through neutral position for bidirectional drive
Integrated charge pump for feeding and control oil supply
Built-in high-pressure relief valves to protect pump and motor against overload
Integrated boost pressure limiting valve for stable charge pressure
Multiple control versions: hydraulic, electric and servo control
Compact structure, high power density for limited installation space
Wide displacement range: 18, 28, 45, 63cc
Strict factory pressure testing to guarantee stable performance
Advantages
Medium high pressure rating up to 300 bar nominal, peak 350 bar, reliable for heavy load
High volumetric efficiency, low heat generation to extend system service life
Fast control response, precise speed and torque regulation
Integrated valve design reduces extra piping and lowers system cost
Excellent interchangeability, standard interface for easy replacement
Robust bearing assembly, strong resistance to shock load in mobile equipment
Low pulsation and stable running, reducing vibration of the whole machine
Mounting Method
SAE J744 2-bolt C flange mounting, compliant with ISO 3019 standard.
Standard shaft is SAE spline type, optional key shaft.
High-pressure A/B ports adopt SAE flange connection, charge suction port at bottom.
Drain port shall be installed upward and keep low backpressure.
The pump can be arranged compactly together with matching hydraulic motor for closed transmission.
Application Range
Road rollers, pavers, small loaders, sweepers, forestry machinery, drilling rigs, agricultural harvesters and other mobile closed hydrostatic drive equipment.
