A multi-stage centrifugal pump is a collection of two or more centrifugal pumps with the same function. The fluid channel structure shows that the medium pressure relief port of the first stage is connected to the inlet of the second stage, and the medium pressure relief port of the second stage is connected. The inlet is connected with the inlet of the third stage, and the mechanism connected in series forms a multi-stage centrifugal pump.

The fire booster and voltage stabilizing complete set of equipment is a set of equipment specially used in fire protection systems. It is designed to provide stable water pressure and flow to ensure rapid and effective water supply when a fire occurs. This equipment usually includes components such as booster pumps, surge tanks, control systems, pipes and valves.

The double-suction pump is a centrifugal pump. Its design feature is that liquid enters the impeller from both sides at the same time, thus balancing the axial force. It is suitable for large flow and low head applications. Double-suction pumps are widely used in municipal water supply, industrial water supply, air conditioning circulating water, fire protection systems and other fields.

Centrifugal pump (Centrifugal pump) is referred to as "centrifugal pump, also called centrifugal pump. It is a water pumping machine that uses the centrifugal motion of water. Before starting the centrifugal pump, the pump should be filled with water. After starting, the rotating impeller drives the water. The water in the pump rotates at high speed, and the water performs centrifugal motion, is thrown out and pressed into the outlet pipe...

A fire pump is a pump specially designed for use in fire protection systems. It is mainly used to deliver water or other fire extinguishing agents to extinguish fires. They are widely used in high-rise buildings, industrial facilities, commercial venues and municipal water systems.

Secondary water supply equipment is a system used to increase and stabilize water supply pressure. It is widely used in high-rise buildings, residential quarters, commercial complexes, industrial parks and other places. Its main function is to transport water to the user through pressurized equipment to ensure the stability and reliability of water supply.

A sewage pump is a pump specifically designed to handle sewage, wastewater and other liquids containing solid particles. It is widely used in municipal drainage, industrial wastewater treatment, construction site drainage and household sewage treatment.
