3. Structural & Performance Features
3.1 Common Features
-
Robust Construction: Three-piece cast iron body ensures high strength, impact resistance, and long service life even in rough working conditions. The fully rebuildable design reduces maintenance costs.
-
Pressure Protection: Direct-acting relief valve with load check function prevents system overpressure, protecting pumps and cylinders from damage. Relief valve pressure can be factory-set to 2000 PSI or 2500 PSI as required.
-
Low Friction Design: Pressure-balanced thrust plates minimize internal leakage and friction, maintaining high efficiency across the entire operating range.
-
Durable Bearings: Heavy-duty roller bearings (USA brand) ensure reliable operation under high loads and extend service life.
-
Flexible Installation: Compliant with SAE and DIN mounting standards, supporting 2-line or 3-line circuit connections for controlling single-acting cylinders. Dual-shaft models (101) can be mounted to remote PTOs, while single-shaft models (102) mount directly to the vehicle drivetrain.

5. Applications
-
G101/102 Series: Light-duty dump trucks, small garbage trucks, municipal maintenance equipment, and cost-sensitive hydraulic systems.
-
C101/102 Series: Medium to heavy-duty dump trucks, large dump trailers, garbage compactor trucks, lifting machinery, and automated hydraulic systems requiring remote control.
6. Operation & Maintenance Notes
-
Use compatible hydraulic fluids (standard hydraulic fluid or phosphate ester) and maintain fluid cleanliness to prevent component wear.
-
Ensure the minimum air pressure of 80 PSI for airshift control systems, which can be supplied by the vehicle’s brake system or on-board compressor.
-
Confirm the required rotation direction (CW/CCW) before installation, as factory-set rotation is usually counterclockwise.
-
Regularly inspect shaft seals, O-rings, and gaskets for leaks; replace worn parts promptly to maintain system efficiency.
-
The pump is covered by a 12-month warranty against manufacturing defects. Contact authorized distributors for maintenance and replacement parts.
