Gear pump for dump truck hydraulic cylinders

1. Pumps and motors are high volumetic efficiency and long life achieved by smart design and accurate control of machining tolerances
2. Fine finished steel gears, Hi-resistant Extruded alluminum body, Hi-resistant Die cast alluminum cover(BAP2) or cast-iron cover(BHP2), Low-friction die casting alluminum bushes, and DU slide bearing, all these keep low pulsation, low noise and long life. 
3. Full option of shafts, flanges and ports as for European, German and America standards
4. Nitrile seals as standard and viton seals available for high temperature application, high pressure shaft seals are also available. 
5. Motor and bi-direction pump available
6. Available as multiple pump either of the same or different group
7. We test 100% of the pumps and motors after assambling to ensure the high standard performance. 
8. Our team have worked in hydraulics for about 20 years. Our technical people are very skilled in producing gear pump. 
9. We have supplied to many world-famous company all over the world. 

1. More secure, rigid integrated limit prove inner tube take out; 
2. More efficient, high-low pressure sealing is adapting to frequent operation; 
3. More widely, adapt to different regions and different working situations; 
4. More powerful, system pressure reaches 20-24Mpa; 
5. More durable, cylinder barrel uses seamless steel pipe, chrome plated on the surface is more reliable;  

Complete set of hydraulic system include: 

Lifting valve: Small size, steady pressure, safe and reliable

•  
• Gear pump: Small size, strong power, long life
•  
• Hydraulic oil tank: Multiple cleaning protection
•  
• Gas valve: Proportional control and easy manipulation
•  
• Limit valve: To optimize the process of use and improve the lifting frequency
•  
• High-pressure oil tube: Durable, dust proof, not rust.
