Self-Priming Pump

AZX series pumps belong to self-priming centrifugal pumps. The key advantage is this type of pump has stronger self-priming capacity.

(1) It does not need install bottom valve on the pipe line, simplified the pipeline system, and improved the working condition, just need to retain quantitative liquid before starting work.
(2) Sewage capacity: special non-clogging impeller design make sure high efficiency and no clog.
(3) Energy saving: adopt excellent hydraulic model, efficiency 3-5% higher than common self-priming pump.

(4) Self-priming capacity: self-priming height 1-3meter higher than common one and self-priming time shorter.



AZX series Self Prime pumps belong to self-priming centrifugal pumps. It is one stage, single suction horizontal water pumps. The key advantage is this type of pump has stronger self-priming capacity.


It does not need install bottom valve on the pipe line, simplified the pipeline system, and improved the working condition, just need to retain quantitative liquid before starting work.
The AZX series self-prime pumps are widely used in the irrigation and general industry department like the power plant, chemical industrial and marine.
