    3.5L/M flow mini water pump/pressure washer pump with self-priming function



    Judging the working condition of exhaust end of miniature pump

    The above problem is to discuss the suction end resistance of the pump. According to these conditions, the range of selection has been reduced, but the problem of exhaust end resistance must be considered. In this way, the optional range can be determined.

    In practical application, the exhaust condition of the micro vacuum pump is different: one is that the exhaust is very smooth and goes straight to the atmosphere; the other is the high exhaust resistance, such as valves, small bends, and large damping sensors on the exhaust pipe road, Non-specific silencers, exhaust below liquid level, gas to airtight or semi-closed containers, etc. In modern design and manufacture, the micro vacuum pump with different exhaust conditions is treated differently. " The parameter of the maximum resistance Por value "is to calibrate the exhaust capacity of the pump, so we can use strict technical means to determine whether the type selection is appropriate or not."

    1. DC motor with long lifetime

    2. Low noise

    3. Continuous operation: The pump can sustain heavy duty work for a day;

    4. Compact design, It has good waterproof;

    5. Low power consumption, high efficient-save on operating cost;

    6. Small and Light-weight, Installation is very simple;

    7. Wide application;

    8. Perfect for indoor or outdoor use;

    9. It can be customized according to customer's technical requirements.

    Our company offers multiple component configurations allowing piston pump to be used for either vacuum operation, pressure operation, or alternating vacuum and pressure operations.The innovative, compact design incorporates leading edge technologies that allow it to operate harder, quieter and longer, reliable, highly efficient.
    Its flow can deliver up to 3 L/min and 3.5L/M.
    Usually our pump has 4 kinds of voltage:6V, 9V,12V and 24V.
    When you choose pump, you can tell me the pump's voltage you need.
    We can do it for you.
    You can choose pump according to our model.
    In addition,it can be mounted in any position.


    Working principle:The rotary motion of the motor makes the driving gear to rotate and the driving gear makes the driven gear to rotate.When the meshing teeth gradually separate on one side of the suction chamber; suction chamber volume is increased; pressure is reduced, the liquid in suction pipe will be sucked into pump. Sucked liquid was divided into two road in gear teeth groove and was pushed to the discharge chamber. After liquid entering into the discharge chamber, because of the two gear tooth meshing unceasingly, the liquid from the discharge chamber into the discharge pipe by extrusion.


    pressure washer pump's application


    Mainly used in household appliances, laboratory equipment, environmental monitoring, gas monitoring, automotive tires and other fields.
