1 The first method (the simplest)

The self -absorbing sewage pump is set on the water pump water absorption pipeline. Before the pump is started, the vacuum pump is started first, so that the water pump water absorption pipe is covered with water to ensure that the pump is automatically and quickly start.

This method of water absorption requires a complete automatic control system to ensure normal work.

2 The second method (simpler)

Self -suction pumps reduce the water inlet pipeline curve, height and horizontal interval.

3 The third method (troubles but easy to use)

Self -suction pump sets the water absorption tank in front of the pump. In this way, a water absorption tank needs to be set on the water pump water absorption pipe. Before the first run, the pump should be filled with water artificially. After the first operation, the height of the water inlet pipe in the water absorption tank is higher than the height of the water surface in the pipe. The height of the water surface in the pool is lower than the can
