product overview

The QZZSC type strong self-priming double suction diesel engine water pump (with vacuum device) can start automatically without the need for water injection and can be automatically controlled (i.e. the vacuum pump set will automatically start when the vacuum degree drops to a low level, and automatically stop when the vacuum degree rises to a high level, without interfering with the operation of the main pump and playing an auxiliary role). It adopts a dry abrasion resistant structure design and can operate for 30 minutes. It can also suck shallow water and air-water mixtures.
This type of water pump solves the problems of high axial tension, long self-priming time, and low efficiency of single suction self-priming pumps. It has the advantages of high suction stroke, short self-priming time, high efficiency, significant energy-saving effect, stable operation, and long service life.
This type of water pump is suitable for various complex emergency rescue, firefighting and other occasions, and is not affected by factors such as power supply and usage site. It can be moved for operation and has high flexibility.
