Description
CBHST1-35 UNI Series Gear Pump
Product Overview
The CBHST1-35 UNI series gear pump is a high-efficiency hydraulic component designed for heavy-duty torque applications. Adopting advanced gear meshing technology and solid cast iron construction, this series complies with both ISO and UNI assembly dimension standards, featuring convenient rear and side oil port designs. It delivers exceptional long-term durability and operational efficiency, making it a reliable choice for various hydraulic systems.
Working Principle
As an internal meshing gear pump, the CBHST1-35 UNI series operates based on the internal meshing principle of gears. The driving internal gear on the main shaft drives the external gear to rotate in the same direction. At the inlet, the gears separate to form negative pressure, drawing in fluid. At the outlet, the continuous meshing of gears squeezes the fluid to realize stable output. A “crescent plate” on the pump cover separates the two gears on one side while they are closely attached on the other, ensuring smooth fluid transfer and efficient pressure build-up.
