Product Introduction
ATUS PD Series variable axial piston pump is engineered for open-circuit hydraulic systems. It adopts rugged cradle-bearing swashplate structure, available in multiple displacements from 18cc up to 140cc. Rated pressure reaches 280 bar, supporting full power through-drive. Widely used for mobile machinery and industrial hydraulic equipment, it serves as a direct replacement for original parts.

Features
Heavy-duty cradle bearing design for stable high-pressure continuous operation
Variable swashplate, adjustable output flow according to system demand
Full power through-drive design for multi-pump combination installation
Optional torque limiter to protect hydraulic system from overload damage
Wide working temperature range, strong adaptability for harsh working conditions
Two shaft options: keyed shaft & spline shaft for diverse connection needs
End inlet / side inlet port optional, flexible pipeline layout
Horizontal or vertical shaft-up mounting available
Hydrostatic balanced swash plate saddle, low friction and long service life
Strict factory pressure test, consistent performance for mass replacement
Advantages
High power density, compact pump body saves installation space
Low noise and low vibration during continuous operation
Multiple control types: pressure compensator, load sensing, remote pressure control
Standard mounting dimensions for easy drop-in replacement
High-strength cast iron housing, anti-impact for construction & agriculture machines
Complete displacement range to match different flow requirements
Easy maintenance, replaceable internal spare parts
12-month warranty with reliable after-sales technical support
Installation Method
Mounting form: SAE standard flange installation, compatible with standard engine/gearbox connection interfaces
Mounting orientation: Support horizontal installation and vertical shaft-up installation; shaft-down installation requires customized case drain design
Port layout: Side inlet/outlet or end inlet/outlet optional, case drain port must be placed at the lowest position of pump body
Shaft connection: Use flexible coupling for prime mover connection; avoid radial and axial overloading on pump shaft
Through-drive version: Multiple pumps can be stacked and mounted in series for combined hydraulic power supply
Installation note: Keep proper oil level of case drain line, prevent air suction and cavitation
Application Range
Construction machinery, agricultural equipment, material handling, road machinery, industrial hydraulic stations, waste recycling machines and other medium & high pressure open circuit hydraulic systems.
