Product Description:

Self-priming Jet Pump


Introduction of Self-priming Jet Pump


It contains three major parts, motor, water pump, and sealing parts. The motor is asynchronous type, and the water pump has a unique structure of centrifugal impeller, radial diffuser and jet pipe. The pressurized water flows through jet nozzle to form vacuum atmosphere, and liquid in low water level is sucked into our product, then pressurized and drained. Thus, self priming function is realized. Meanwhile, single mechanical seal is used as the motive seal between motor and water pump, and rubber O ring is used as the static seal for rabbet.


Features of Self-priming Jet Pump


This jet pump is well designed, and it has compact structure. Compared with similar product, our machine has higher working efficiency as well as quieter and more stable running due to the reasonable structure. When the check valve is equipped, the cavity only needs to be filled with water for the initial use which means that this process is unnecessary for the later applications. On the other hand, our product also features reliable sealing, little leakage, high reliability, convenient maintenance, low running cost, long service life, etc


Application of Self-priming Jet Pump


Depending on the advantages above, our jet pump is widely used for farm irrigation, sprinkling irrigation for garden, water supply system for vegetable greenhouse as well as water supply and drainage system for breeding industry, and it is also suitable for lifting water from well, tap water pressurizing and other household applications.
