1) Low efficiency. This is because the water loss is very large during the working process of the jet pump. When deviating the best working conditions, the efficiency is lower.

2) The structure is simple, the volume is small, and the price is low.

3) No motion components, reliable work, small noise, long service life, usually no maintenance repair.

4) The starting start is rapid, and it can be created high and the self -priming ability is strong.

5) The dirty liquid containing solid impurities can be transported, and it can work properly even if it is immersed in water.

The water jet pump is mainly used as a rush capsule bottom pump, and occasionally working cargo cabin drainage pumps and vacuum pumps.
