The ZYB adjustable heavy oil pump features a gear end face gap adjustment structure. When the pump's pressure drops after a period of operation, the internal gear end face gap can be adjusted by using the external fine-tuning mechanism on the pump cover. This allows the pump's operating pressure to be restored and can be adjusted multiple times, thereby extending the effective service life of the pump.

The ZYB adjustable residual oil pump features a gear end face clearance adjustment structure. When the pump experiences pressure drop after operating for a period, the clearance inside the pump can be adjusted using the external fine-tuning mechanism on the pump cover. This restores the pump's operating pressure and allows for multiple adjustments, thereby extending the pump's effective service life. This pump is mainly used for transporting diesel, heavy diesel, and other low-pollutant fuels at temperatures below 200°C, as well as in high-pressure applications.

The ZYB adjustable waste oil gear pump series comes with the following factory configuration: Standard: Pump head, Coupling; Optional: Pump base, Motor, Filter.
