1. Unique strong self-priming automatic control function, with high suction range, fast self-priming, and the ability to start self-priming without the need for water injection and automatic control. It is particularly suitable for use in locomotive integrated mobile pump stations as a water supply and drainage equipment, and can be widely used in flood control, drainage, firefighting and other occasions.
2. Due to its fast self-priming, it greatly reduces the self-priming time by 60%, effectively improves operational efficiency by more than 50%, increases suction height by more than 30%, and extends its service life, achieving durability, stability, practicality, economy and other functions of use.
3. Due to the use of a unique double suction self-priming vacuum pump set and the clever combination design structure of the automatic control system, it is more widely used in high flow and large diameter applications. Because of the double suction structure, water enters the impeller at both ends and is discharged in the middle without axial tension, so there is no upper limit on the flow rate and port diameter. The normal diameter is between DN100~DN600, and the flow rate is between 100 tons and 3000 tons. The non-standard diameter flow rate can be customized.
4. It can work normally without the need for water injection during use, is resistant to dry abrasion, and does not require a bottom valve, which is fundamentally and structurally different from other products. Due to its strong self suction and automatic control functions, it has high suction range and fast self suction start, which can automatically control (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 with multiple functions, without interfering with the operation of the main pump and playing an auxiliary role).
5. The newly adopted automatic water diversion device introduces a new mode of using a built-in mechanical floating ball valve and monitoring probe, which improves the reliability of the equipment. Even if the vacuum pump is running continuously and the water level in the water tank reaches a certain position, the mechanical floating ball valve will automatically close due to buoyancy, preventing water from entering the vacuum pump and providing dual protection for the vacuum pump, preventing damage to its components due to water ingress. Added a water blocking valve, installed on the external pipeline, which can effectively block water vapor from entering the vacuum pump.

product overview

The QZZS strong self-priming double suction pump series is an upgraded second-generation new structure pump product of our company based on the original first generation multifunctional double suction self-priming pump. It solves the problems of low suction stroke, slow suction, inability to self suction without water injection, and inability to start dry that existed in the first generation multifunctional double suction self-priming pump.
