Why are sanitary pumps used?

Efficient fluid transportation

High flow transmission capacity

Centrifugal pumps can transport fluids at relatively high flow rates. This is because it uses centrifugal force to push the fluid. When the impeller rotates, the fluid enters the impeller and is thrown towards the edge of the impeller by centrifugal force, thereby obtaining energy. For example, in large-scale water supply systems such as urban tap water pumping stations, centrifugal pumps can transport large amounts of water from water plants to various areas of the city. Assuming a centrifugal pump in a city's water supply pumping station has a flow rate of thousands of cubic meters per hour, it can meet the water needs of numerous residents and businesses.

High energy conversion efficiency

Centrifugal pumps efficiently convert mechanical energy (usually from motors) into kinetic and pressure energy of fluids. The energy conversion process is relatively simple, mainly achieved through the rotation of the impeller. Compared with some positive displacement pumps, centrifugal pumps have higher energy utilization efficiency when transporting low viscosity fluids such as water. In industrial production, such as chemical plants transporting various liquid raw materials, centrifugal pumps can transport fluids to equipment such as reaction vessels with low energy consumption.

Structural and operational advantages

Simple and compact structure

The structure of a centrifugal pump is relatively simple, mainly composed of pump casing, impeller, shaft, sealing device and other components. This simple structure makes it easy to manufacture and maintain. For example, for some small centrifugal pumps, maintenance personnel can easily replace worn impellers or seals. Moreover, its footprint is relatively small, and in situations where space is limited, such as the engine room of a ship or the equipment room of a small factory, centrifugal pumps can adapt well to the environment.

Easy and reliable operation

The start-up and operation of centrifugal pumps are relatively simple. Generally, only the power supply needs to be connected, the motor needs to be started, and the pump can work normally. It has relatively low requirements for fluid suction conditions, unlike some positive displacement pumps that require strict pumping operations. During normal operation, as long as the supply of fluid and the normal operation of the motor are ensured, the centrifugal pump can stably transport fluid. Moreover, its operating noise is relatively low, and in some places that have certain requirements for environmental noise, such as hospital liquid supply systems, centrifugal pumps are a more suitable choice.

Strong adaptability

Can transport multiple fluids

Centrifugal pumps can transport various fluids such as water, oil, acid, alkali, etc. By selecting appropriate materials to manufacture the overcurrent components of the pump, for example, for transporting acidic liquids, corrosion-resistant stainless steel or special alloy materials can be used to make the impeller and pump casing. In the food processing industry, centrifugal pumps can transport liquids such as milk and juice. As long as the cleanliness and hygiene conditions of the pump are ensured, it can meet the transportation requirements of the food industry.

Adapt to different flow and pressure requirements

By changing the diameter, speed, or stage of the impeller, centrifugal pumps can meet different flow and pressure requirements. For example, in some situations that require a higher head (i.e. the height at which the liquid is lifted), such as water supply in high-rise buildings, the pump head can be increased by increasing the number of impeller stages. For different flow requirements, the flow rate of the centrifugal pump can be flexibly controlled by adjusting the motor speed or changing the valve opening of the pipeline system.
