NCB Series Hydraulic Internal Gear Pump Overview

NCB Series Hydraulic 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.

Features and Benefits

• Pressure-Compensated Design
  Adopts axial and radial pressure compensation to maintain high volumetric efficiency even at low speed and low viscosity. The pump operates quietly with low internal noise, ensuring stable performance under varying conditions.

• Low Flow and Pressure Pulsation
  Very low flow and pressure pulsation, providing stable output at low speeds. The design allows working pressures up to 35 MPa, suitable for demanding hydraulic 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 for complex hydraulic circuits.

• Contamination Resistance & Long Service Life
  Resistant to oil contamination, ensuring reliable performance in harsh environments. The robust design delivers a long service life and consistent efficiency.
