Gear Pump | Various types of Gear Pump-Nanotejarat

Haldex gear pump

The Haldex gear pump is made of alloy steel with tempering and nitriding, providing 55–60 HRC surface hardness. Displacement ranges from 12 to 25 cc/rev, supporting operating pressures up to 210 bar. Internal gear diameter is 35 mm, external gear 50 mm, with ±0.02 mm tolerance to minimize internal leakage and achieve volumetric efficiency above 92%.

The pump body design optimizes oil flow, maintaining operating temperature between 60 and 90°C. Journal bearings are rated for 1,500 N radial load, and the pump weighs approximately 6.5 kg. Internal lubrication grooves reduce friction, extending service life up to 5,000 hours under standard conditions. Corrosion- and wear-resistant coatings maintain stable performance efficiency.

Commercial Roller Gear Pump

The Commercial Roller Gear Pump is made of alloy steel with tempering and nitriding, providing 55–60 HRC surface hardness. Displacement ranges from 20 to 40 cc/rev, with operational pressure up to 180 bar. Roller diameters are 30 mm internal and 48 mm external, with ±0.02 mm tolerance to minimize internal leakage and ensure volumetric efficiency above 90%.

The pump body features optimized channels for lubrication and cooling, maintaining operating temperatures between 65 and 95°C. Bearings are designed for 1,200 N radial load, and the pump weighs approximately 7 kg. Internal oil grooves reduce friction and extend service life up to 4,500 hours. Corrosion- and wear-resistant coatings ensure stable long-term performance.
