Product Description
QT Series Hydraulic Pump Gear Shaft Gear Pumps are developed by our company and American Albert Fluid Power Co., LTD. (Ningbo NVICKS Hydraulic Co.,LTD., a wholly owned subsidiary; short for ABT) , cooperated with Zhejiang University . They're high performance internal gear pumps. The technology on the basis of the introduction of Germany to be improved,and we introduced a number of foreign advanced production and testing equipments, to make a pump of high pressure, low noise and low pulse.
Our company has independent intellectual property rights and National Innovation Fund support, widely used in rubber and plastic, die casting, shoe leather, forging, extrusion, bending, plate Shearing machinery and other servo hydraulic system.
Pressure-Compensated Design
Adopts axial and radial pressure compensation to maintain high volumetric efficiency even at low speed and low viscosity. Ultra-low noise ensures smooth and stable operation in various hydraulic systems.
Low Flow and Pressure Pulsation
Very low flow and pressure pulsation, providing stable output at low speeds. High-pressure design allows working pressures up to 35 MPa for demanding applications.
Wide Speed Range & Modular Design
Operates efficiently over a wide speed range, up to 3000 r/min. Multiple units can be combined to form double or multi-pump assemblies for flexible system integration.
Dual Pump Capability
Can be configured as a double pump, enabling versatile system operation and multi-function integration in complex hydraulic circuits.
Contamination Resistance & Long Service Life
Resistant to oil contamination and wear, ensuring reliable performance and long service life in harsh industrial or mobile environments.
