    Tips: Reasons for the high temperature of electric diaphragm pump

    • Water leakage or insufficient cooling water in the cooling system.
    • Inaccurate or malfunctioning water temperature indicator.
    • Too much scale in the cooling system and poor heat dissipation effect.
    • The radiator shield net or the radiator core air passage is blocked by debris, resulting in poor heat dissipation.
    • The belts of the water pump and fan are too loose or broken.
    • The electric diaphragm pump is damaged, the fan blades are reversed or deformed, and the wind ring is damaged.
    • The thermostat is damaged in the closed position of the main valve.
    • Long-term overload operation of the engine and late fuel supply time, etc.
    • Check whether a valve is installed at the outlet.

    Works as promised.
    I bought this electric diaphragm pump last week, arrived fast and worked as promised. Easy to hookup and install. This pump does the job and is very quiet. It really saved me a lot of time and at a terrific price. I highly recommend this model.
