Volvo loader steering hydraulic pump
The Volvo loader steering hydraulic pump is made of alloy steel and durable aluminum, supporting operational pressures up to 250 bar. Pump flow rate ranges from 45 to 110 L/min, and shaft tolerance is ±0.02 mm to minimize internal leakage and maintain volumetric efficiency above 92%. Internal gears or pistons are heat-treated to 55–60 HRC surface hardness to reduce wear and friction.
Internal lubrication channels and cooling grooves maintain operating temperature between 65 and 95°C. Radial and axial bearings rated for 1,500 N control vibration and axial forces. Pump weight is approximately 12–16 kg, with service life up to 5,000 hours under standard conditions. Corrosion-resistant coating and hardening ensure long-term, stable performance.
