CBXB Series Gear Pump

CBXB Helical Ultra-Quiet Gear Pump

1. Independently designed high-precision helical gear products with optimized curve parameters, achieving noise levels below 55 dB(A) under rated operating conditions. 2. The front cover reduces the high-pressure zone, while the rear cover incorporates a high-pressure pin‑shaft mechanism to eliminate radial forces; combined with a dedicated floating shaft sleeve, this design delivers robust load‑carrying capacity and high reliability. 3. Minimizes pulsation and vibration during pump operation without causing energy loss. 4. Offers higher volumetric efficiency and reduced power consumption at low speeds, enabling operation at varying speeds under the same throttling conditions. 5. Cost savings are achieved by eliminating additional noise‑control measures.
