1. JYB-40 self-priming DC fuel pump is widely used in large mobile construction machinery, vehicles and small vessels. It uses the vehicle (ship) battery as power, and is more suitable for worksite and field operations, regardless of geographical and power supply. Restrictions reduce the labor intensity of personnel, improve work efficiency, and increase economic efficiency.

Second, JYB—40 self-priming DC fuel pump has the characteristics of light weight, small volume, long life, low noise, convenient installation and carrying, etc. The pump adopts high-precision internal gear wheel structure, which has good self-priming ability and does not produce oil. Contamination (vane pump blade wear can cause oil contamination); it is equipped with positive and negative switches to make the fuel pump have positive and negative suction and discharge functions (this is not possible with the vane pump).

Third, technical parameters

4. JYB—40 series pumps are used for oil transportation of diesel oil, hydraulic oil, saponified oil and engine oil. It is strictly forbidden to use the very easy fuel gas transportation such as dry gasoline and banana water. Please refer to the instruction manual before use.
