Product Advantages
Load‑Sensing energy‑saving control: Only outputs required flow according to load demand, reduces power loss and oil temperature rise, improves fuel efficiency of host machine
High power density: Compact E‑frame housing, large displacement within small installation space, convenient for host layout
Stable pressure compensation: Fast response to load changes, keep system pressure stable under variable working load
Heavy‑duty mechanical structure: Resists impact and vibration, adapts to dusty, high‑temperature harsh mobile working environment, long service life
Good system compatibility: Matches various valves, motors and hydraulic accessories; simple maintenance and spare‑part replacement
Application Scenarios
This is open‑circuit load‑sensing main pump for medium‑large mobile machinery, supplies pressure oil for working hydraulic system, steering and auxiliary circuits.
Road construction machinery
Asphalt paver: Provides power for screed lifting, material feeding, conveyor and walking auxiliary hydraulic circuit. LS control matches variable load of paving operation, keeps stable action and avoids speed fluctuation, guarantees pavement flatness.
Soil compactor / road roller: Drives vibration system, steering and auxiliary actuators, adapts frequent start‑stop and impact load during compaction work.
Road milling machine: Supplies hydraulic power for milling drum lifting, conveyor and travelling auxiliary system, copes with sharp load fluctuation in milling condition.
Agricultural machinery
Large combine harvester: Powers header lifting, reel, auger, walking auxiliary and steering hydraulic circuits. LS energy‑saving feature reduces engine load under field muddy complex working conditions.
Large tractor: Main hydraulic pump for hitch lifting, front loader and multi‑way valve working circuit, supports multiple actuators simultaneous operation.
Material‑handling & engineering machinery
Telescopic handler: Drives boom lifting, telescopic action and steering system, realizes multi‑action compound movement with low heat generation.
Large forklift & container handler: Main hydraulic power for lifting, tilting and attachment movements.
Forestry & municipal machinery
Forest harvester, wood chipper: Provides power for manipulator arm, feeding and cutting mechanism under heavy variable load.
Sanitation truck, snow‑removal equipment: For lifting, swinging and working tool drive, adapts continuous outdoor operation.
Special mobile & offshore auxiliary equipment
Mobile hydraulic power unit, special modified engineering vehicle; auxiliary hydraulic system for offshore deck machinery, works under high vibration environment.
