QZZS Strong Self priming Mud Pump

QZZS Strong Self priming Mud PumpProduct Features:

1. The strong self-priming automatic control function has high suction range, ultra fast self-priming, and can start and control automatically without the need for water injection. 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, fire protection and other occasions.
2. Due to its ultra 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 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 diameter. The normal diameter is between DN100~DN600, and the flow rate is between 100 tons and 3000 tons. Non standard flow rates can be customized regardless of the diameter or size.
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-priming and automatic control functions, it has ultra-high suction range and ultra fast self-priming start that can be automatically controlled (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 float ball valve and monitoring probe, greatly improving 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 float 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.

High suction range and strong self-priming mud pumpScope of application:

The ambient temperature is ≤ 50 ℃, the medium temperature is ≤ 80 ℃, and special requirements require a temperature of up to 200 ℃.

The pH value of the medium is 6-9 for cast iron and 2-13 for stainless steel

Medium poisoning not exceeding 1240kg/m3

The self-priming height of ordinary self-priming pumps cannot exceed the specified value of 5-7 meters, and the length of the suction pipe is ≤ 10m. The vertical height of high suction self-priming pumps can reach 9 meters, and the horizontal distance exceeds 200 meters.

The QZZSW sewage type has a suspended particle diameter of about 20% of the pump diameter and a fiber length of about 5 times the pump diameter.

High suction range vacuum assisted self-priming pumpMaintenance requirements
1. Before maintenance and cleaning of the self-priming pump, ensure that the power supply is turned off, the residual liquid in the pump body is discharged, and the inlet and outlet are closed. Maintenance personnel should wear protective clothing and face shields, safety shoes, and socks
2. Regularly check the access buttons to prevent foreign objects from blocking the pump body and causing the motor to spin and burn out the pump.
3. The combination of motor and pump must be calibrated accurately to make the motor and pump in the same line.
4. The shaft seal cover is fixed on the rear axle seal, and when the rear cover is locked on the foot seat, it must be in the center of the pump.
5. The fixing screw of the impeller locks the impeller in a clockwise direction. The gap between the impeller and the middle cover is about 1-1.5mm, and the size of the gap will wear out the impeller.
