Green Hydraulic
A20VO/A20VLO series
Standard export carton/plywood case
YES
ISO9001 CE
1 set
Product Description
A20VO: Medium displacement versions (60cc, 95cc), standard self-priming structure for medium-load equipment
A20VLO: Large displacement versions (190cc, 260cc), built-in integrated charge pump to optimize oil suction stability under large-flow working conditions
Rated working pressure reaches 350 bar (5076 psi), instantaneous peak pressure 400 bar (5802 psi). Core friction components adopt mature structures inherited from A10VO and A4VSO pumps, delivering stable volumetric efficiency and extended service life under long-term high-pressure operation.
Full through-drive structure: Supports serial installation of gear pumps or auxiliary piston pumps, simplifying the overall hydraulic pipeline layout of host equipment
Multiple optional control modes: DR constant pressure, LR constant power, LRD constant power with pressure cut-off, DFR and electro-proportional control; constant power parameters can be externally adjusted during pump operation
Stepless flow regulation: Output flow can be adjusted steplessly from maximum displacement to zero displacement, with outstanding energy-saving performance under variable load conditions
Optimized internal flow channel: Low vibration, low running noise, excellent resistance to hydraulic oil contamination
Standard installation structure: Adopts SAE flange and spline shaft standard; direct replacement is available for equipment maintenance without modifying mechanical structures
High-strength cast iron housing: Strong pressure resistance, impact resistance and durable sealing performance for harsh construction site environments
Specifications
Applications
Support heavy hydraulic presses, metallurgical equipment, large injection molding machines and bulk material conveying hydraulic stations with stable high-pressure oil supply.
Factory&FAQ
A20V Pump A20VO60/95/ Pump A20VOL190/260 are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
1. What is the A20V Pump A20VO60/95/ Pump A20VOL190/260 ?
The A20VO / A20VLO series are back-to-back tandem swash-plate variable axial piston pumps designed for open hydraulic circuits.
A20VO includes 60cc and 95cc medium displacements, while A20VLO covers 190cc and 260cc large displacements equipped with an integrated charge pump.
This pump runs at a rated pressure of 250 bar and a peak pressure of 310 bar. Multiple control modes are optional, featuring a through-drive design, high efficiency and strong anti-pollution ability. It is a main hydraulic power source widely used in medium and heavy construction machinery.
2. What makes the A20V Pump A20VO60/95/ Pump A20VOL190/260 ?
This series adopts a mature back-to-back double pump layout with optimized swash plate and precision friction assemblies including cylinder blocks, pistons and valve plates, ensuring stable volumetric efficiency under high pressure up to 400 bar.The A20VLO version adds a built-in charge pump to improve oil feeding stability for large displacement working conditions.Equipped with a full through-drive structure and optional multiple control valves, the cast iron pump casing brings outstanding shock resistance and dirt tolerance. Standard SAE installation dimensions enable direct replacement of original brand pumps for construction machinery hydraulic systems.
3. What is the working pressure range of A20V Pump A20VO60/95/ Pump A20VOL190/260 ?
Nominal working pressure: 350 bar (5076 psi)
All models (60, 95, 190, 260) follow this unified pressure parameter standard.
4. Can A20V Pump A20VO60/95/ Pump A20VOL190/260 replace other brands?
External overall dimensions, SAE mounting flange, spline shaft size, port layout and valve installation interfaces are strictly produced in accordance with original drawings, supporting direct installation without modifying equipment structures.
Consistent pressure parameters (350 bar rated, 400 bar peak), internal friction pair structure and control principle match the original system operating requirements perfectly.
Matching the same displacement, control type and rotation direction is the basic prerequisite for smooth replacement. Our pumps also support OEM marking to meet your brand replacement demands.
5. What is the typical speed range of A20V Pump A20VO60/95/ Pump A20VOL190/260 ?
A20VO60: Rated speed 2700 rpm, maximum permissible speed 3140 rpm
A20VO95: Rated speed 2350 rpm, maximum permissible speed 2780 rpm
A20VLO190: Rated working speed 2500 rpm
A20VLO260: Rated working speed 2300 rpm
6. Do you provide OEM or customized services?
OEM service: We can print your exclusive brand logo, custom part numbers and information on pump housings and nameplates; neutral packaging or branded dedicated packaging is available as requested.
Customizable items: Adjustable control modes, shaft spline specifications, rotation direction, seal materials and pump surface paint color. We can also tweak internal parameters to fit special harsh working conditions.
We are capable of developing products according to your drawings or samples to support long-term bulk matching supply.
