AWZB-A automatic peripheral self priming pump is composed of motor, water pump, sealing part and control system. It is equipped with mechanical pressure switch, and the 8L/19L pressure tank guarantees better buffering property as well as more stable working. Based on the water pressure, the control system is able to realize the automatic running of our product. When the valve is open, this machine automatically works, and it will automatically stop without manually cutting off power supply if the valve is closed.

This pump has asynchronous motor and peripheral impeller, and it can provide water at stable pressure. Meanwhile, our product is self-priming type, and it features small flow, high head, small size, light weight, compact design, convenient installation, etc. Thus, this safe, efficient and energy saving machine is perfect for household applications. On the other hand, this peripheral pump is also suitable for water lifting from well, irrigation for garden and vegetable greenhouse, water supply and drainage in breeding industry, pressurizing for pipeline, water tower and tap water, etc.

Configurations and Functions
Name Code Configurations Functions
Flagship type H1 Flow switch, pressure switch, control panel, 2L pressure tank, anti-rust impeller The control system is able to start or stop pump at proper time based on the water pressure and flow. Stable water supply is realized, and water shortage protection is also available.
Automatic type K Visible and adjustable electronic pressure switch It is equipped with electronic pressure switch and pressure gauge, and the start and stop pressures can be adjusted according to the actual working pressure. Thus, automatic pressurized running is achieved.
AK Visible and adjustable electronic pressure switch, 8L/19L pressure tank
Ordinary type
Mechanical pressure switch, 2L pressure tank The common mechanical pressure switch can control the start and stop of machine depending on the water pressure. The working pressure of switch should be adjusted according to different water sources.
