1. Unique strong self-priming automatic control function, with high suction range, fast self-priming, and automatic control without the need for water injection. It is 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, fire protection and other occasions.
2. Due to its fast self-priming, it reduces 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 self-priming vacuum pump set and the combination design structure of the automatic control system, it is more widely used in high flow and large diameter applications. The normal diameter ranges from DN100 to DN600, with a flow rate of 100 to 3000 tons. Non standard diameter flow rates 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. Due to its strong self suction and automatic control functions, it has a high suction range and can automatically control the quick start of self suction (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.
