Product

A4VG Series Piston Pump

Product category：Hydraulic drive, control and process control engineering

A4VG swash‑plate axial piston variable pump is designed for closed‑circuit hydrostatic transmission, with sizes 45‑280, nominal pressure 450 bar and max pressure 500 bar. Flow is proportional to speed and displacement. Stepless flow adjustment is achieved by swash‑plate angle regulation, enabling smooth oil‑flow reversal across zero‑position. Multiple controls are available: hydraulic proportional, mechanical servo, electric proportional and speed‑dependent auto‑control. Two high‑pressure relief valves protect pumps and motors from overload and serve as charge valves. The integrated charge pump supplies charge and control oil, with its pressure limited by a built‑in low‑pressure relief valve. It supports through‑drive for A4VG‑A4VG tandem assemblies, featuring pressure cut‑off, bypass and mechanical stroke limiter. High power‑density and efficiency suit heavy‑duty mobile machinery closed‑circuit systems.

A10VO Series Piston Pump

Product category：Hydraulic drive, control and process control engineering

The A10VO swash‑plate axial piston variable pump applies to open‑circuit hydrostatic transmission, covering sizes 10‑180, nominal pressure 250‑280 bar and max pressure 315‑350 bar. Flow varies with speed and displacement via stepless swash‑plate angle adjustment. It offers versatile controls including DR, DRG, DFR, ED and ER with short response time. Some models feature hydrostatic yoke‑bearing unloading for good suction performance and high rotating speed. Equipped with dual case drain ports, selected sizes support 100% through‑drive for tandem pump combinations. It delivers high power‑to‑weight ratio, compact layout, low noise and strong radial‑axial load resistance, widely used as power source for mobile machinery open‑circuit systems.

Reducer

Product category：Hydraulic drive, control and process control engineering

Featuring compact planetary gearing, this reducer fits wheel‑/track‑type mobile equipment and rotary components for confined mounting spaces. Its surface‑hardened gears and precision‑machined ring gear work with robust planetary bearings for low‑noise operation. An integrated multi‑disc spring‑applied parking brake matches various torque ranges, optimized for plug‑in hydraulic motors with high overall efficiency. Axial mechanical sealing resists moisture and dust. External oil change simplifies maintenance; optional mechanical disengage protects hydraulics during emergency towing. Available in 2‑/3‑/4‑stage designs (size 1000‑9000), it supports custom ratios and dimensions, complying with international gear standards for diverse mobile machinery.

H1B Series Motors

Product category：Hydraulic drive, control and process control engineering

The H1B motor adopts optimized surface treatment and high‑stiffness springs for fine high‑speed performance at small swing angles. Its bent‑shaft design delivers compact dimensions. Electrical components achieve IP67 and IP69K high protection ratings. Optimized dead volume, end‑cover and valve sections cut control losses and boost efficiency. One‑piece housing and heavy‑duty spline joints enhance dynamic torque output, sustaining 450 bar pressure differential for high‑power operation. Accessible outer shaft seal and H1‑series common‑platform design simplify service and part interchangeability. It fits heavy‑duty equipment in agriculture, construction, material handling, forestry and offshore oil‑gas industries.

D1P Series Plunger Pump

Product category：Hydraulic drive, control and process control engineering

The D1P series is heavy‑duty open‑circuit variable axial piston pump for heavy‑vehicle open hydraulic circuits. It offers displacements of 130, 145, 193, 260 cm³, max working pressure 350 bar, peak intermittent pressure 400 bar and maximum input speed 2500 rpm. It supports power, constant‑pressure, electric‑proportional displacement and load‑sensing controls. Reinforced for harsh conditions, it features swash‑plate servo control, good self‑priming and spherical valve plate for high efficiency. Optional integrated boost pump enables better cold‑start performance. Full through‑drive allows tandem mounting. Compatible with PLUS+1 components, it applies to concrete, mining, drilling, port, marine and construction machinery under severe heavy‑duty conditions.

S45 Series Open-Circuit Axial Piston Pump

Product category：Hydraulic drive, control and process control engineering

The S45 series is high‑performance open‑circuit axial variable piston pump, with displacement 25‑147 cm³, max speed 3600 rpm and continuous pressure 310 bar. It supports load‑sensing, pressure‑compensated and electric torque‑control modes. Optimized by QFD & DFM, its rigid one‑piece housing reduces leakage and noise. Heavy‑duty tapered roller bearings extend service life, while integrated controls shorten response time. Gasket‑free construction and built‑in sensing port ensure proven reliability. With through‑drive capability and compact layout, it delivers high efficiency and low heat generation for smaller coolers.
