ZCB-B Series Gear Pump – This low-pressure, high-flow external helical gear pump is manufactured using advanced foreign design and production technology. It features a compact structure, low noise, excellent sealing performance, and high efficiency. The pump is equipped with a safety valve that automatically opens when the working pressure reaches ≥2.5 MPa, preventing damage to the gearbox or other transmission devices caused by excessive pressure during startup. The ZCB-B pump is primarily used in high-power gearboxes, and can also be applied in hydraulic systems for construction, mining, machinery, and machine tools.
