The CBT-306 gear pump is an external meshing medium-high pressure hydraulic gear pump and a core power component of hydraulic systems. It realizes oil suction and discharge through the rotation of a pair of meshing gears, converting mechanical energy into hydraulic energy to supply pressurized oil with stable pressure for the entire hydraulic circuit.
The pump adopts high-quality brushed aluminum pump body, reinforced end cover and high-density steel meshing gears as its main core components. It is also equipped with floating bushings with built-in internal leakage grooves and heat-resistant & corrosion-resistant skeleton oil seals. With well-matched structure, internal leakage of the pump is effectively controlled and gear meshing condition is optimized. Featuring stable operation, high output pressure and low running noise, it has a remarkably longer service life than ordinary gear pumps and is widely used in small and medium-sized hydraulic systems.
Product Features
The pump body of CBT-306 is made of brushed aluminum alloy, which is light in weight and has excellent thermal conductivity. It can quickly dissipate heat generated by friction during operation and has good impact resistance. The matched reinforced end cover improves the overall structural rigidity of the pump. It resists end cover deformation and sealing surface warpage under high-pressure working conditions to guarantee structural stability.
The internal gears are precision machined from high-density steel with high tooth profile accuracy, smooth meshing and low wear rate, capable of withstanding high-pressure loads for long periods. The floating bushing is designed with special internal leakage grooves, which can automatically compensate the gear end face clearance, reduce internal leakage under high pressure, maintain high volumetric efficiency and stabilize output pressure.
The sealing part is fitted with heat-resistant and corrosion-resistant skeleton oil seals. It has good compatibility with conventional hydraulic oil and lubricating oil, tolerates a certain range of oil temperature changes, and is not prone to oil seal hardening and leakage failure.
The whole unit runs smoothly with low meshing impact and low working noise, suitable for working scenarios with noise control requirements. It has a compact structure, easy disassembly and maintenance, and highly interchangeable spare parts.
