product overview

The QZZSC strong self-priming double suction diesel engine water pump (with vacuum device) is a new energy-saving double suction self-priming pump product developed by our company according to market demand. Filling the market demand for this type of pump, it can start and automatically control without the need for water injection (i.e. when the vacuum degree drops to a low level, the vacuum pump group automatically starts, and when the vacuum degree rises to a high level, the vacuum pump group automatically stops, without interfering with the operation of the main pump and playing an auxiliary role). It adopts a dry abrasion resistant structure design, can run for 30 minutes, and can suck shallow water and air-water mixtures.
This type of water pump completely 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.
