Industrial pumps

How to select industrial pump?

Industrial pump is the second most used machinery after motor. It has a wide range of practical applications, such as, thermal and nuclear power plants, shipbuilding industry, oil drilling, equipment for chemical and petroleum production, mining and metallurgical industry, textile industry, paper industry, food industry, etc. When planning to set up pumping machinery and system, for any type of industry, it’s important to consider the following points:

.The function, application, and liquid transport characteristics of the pump
.Confirm the power supply, installation space, and operation mode
.Confirm the power supply, installation space, and operation mode
.Comprehensive consideration of equipment procurement and future operation, maintenance, management costs
.Understand the technical support the manufacturer can provide and the status of the parts supply

Comprehensive system planning and product evaluation are critical for smooth operation and efficiency. The impact of unexpected equipment shutdown is often very huge, especially for enterprises. Therefore, it’s very important to ensure good maintenance and timely supply of parts in the future.

Non-Seal/sealless pump

    Industries: petrochemicals, chemicals, gas, semiconductor, power plant, steel, food


Non-seal/sealless pump is a type of centrifugal pump but its unique feature is the non-seal shaft design. Compare to the traditional mechanical shaft-sealed centrifugal pumps, non-seal pumps do not have leakage problem. This feature allows for the transportation of special or dangerous liquids and can ensure a safe work environment as well as environmental protection. Non-seal pumps can be divided into 2 types: canned and magnetic.

Non-seal canned pump integrates the pump and motor into one unit and seals the medium in its canned-like structure during operation to avoid leakage.

Sealless magnetic drive pump is driven by a pair of inner and outer magnets installed between the impeller and the motor shaft. When the motor drives the outer magnetic ring, it is magnetically coupled with the inner magnetic ring on the impeller to generate coupling torque. The torque provides power to the shaft to drive the impeller to conduct liquid transportation.

Because of its non-leakage advantage, the non-seal/sealless pump can be used to handle flammable, explosive, highly acidic, highly alkaline or toxic liquids. Its application includes PCB manufacturing, chemical industry, filtration and recirculation, etching, electroplating, surface treatment, sewage treatment, and etc.

Reciprocating pump

    Industries: petrochemicals, chemicals, gas, semiconductor, power plant, steel, food

Reciprocating pump is a type of pump that uses either the piston or plunger in the cylinder to change the volume formed by the piston or plunger and cylinder wall, to build up liquid pressure from suction to discharge. Reciprocating pump generates high pressure but lower flow rate. It is applicable for transporting liquid with high pressure.

Diaphragm metering pump is a type of reciprocating pump. It is developed by using the fixed flow characteristics of the reciprocating pump. A diaphragm is installed between the plunger and liquid end. Pressure is built by hydraulic pressure. It is characterized by high accuracy. It can continuously adjust the stroke length in the range of 0% – 100% when the pump is still or running. It is suitable for various fluid and pressure conditions. Diaphragm quantitative pump is widely used in petrochemical, chemical, electric power, water treatment, pharmaceutical, and other industrial processes to quantitatively transport all kinds of chemical additives.

Centrifugal pump

    Industries: petrochemicals, chemicals, gas, semiconductor, power plant, steel, food

The centrifugal pump relies on the effects of the rotating impeller on the liquid to transfer the mechanical energy of the motor to the liquid. Fluid enters axially through eye of the casing, is caught up in the impeller blades, and is whirled tangentially and radially outward until it leaves through all circumferential parts of the impeller into the diffuser part of the casing. The fluid has gained both velocity and pressure while passing through the impeller. Then the doughnut-shaped diffuser, or scroll, section of the casing decelerates the flow and further increases the pressure. Its operation relies primarily on centrifugal force, hence the name, centrifugal pump.

Centrifugal pump has many advantages, such as wide range of application, high speed, large flow, easy to increase or decrease pressure when combined with multi-stage impeller, low construction cost, easy disassembly and maintenance, etc. Although it started late, it can take the place of most other types of pumps, and has a 70-80% share in the industrial pump market, becoming the favorite in today’s industry. Its main applications include: liquid transportation, cooling system, industrial cleaning system, aquaculture farm, fertilization system, metering system, industrial equipment, and so on.

Submerged pump

    Industries: petrochemicals, chemicals, gas, semiconductor, power plant, steel, food


Submerged pumps are also called diving pumps or water pumps. It is a mechanical device immersed in liquid for suction and transportation of liquid. From a commonly used classification of pumps, submerged pump is also a type of centrifugal pump. But its unique feature is that its motor is combined with the pump, and drives the main shaft and impeller through rotation to generate centrifugal force, thereby completely liquid transportation. And since submerged pump is immersed in liquid for long periods of time, its design includes water seal, oil seal, air seal, and other structures that prevent liquid leakage.

Submersible pumps can be used to extract groundwater from deep wells, rivers, reservoirs, canals, and other pumping projects, as well as for water supply and drainage in cities, factories, railways, mines and construction sites. Additionally, there are cryogenic submerged pumps specifically used to transport cryogenic liquids (such as liquid oxygen, liquid nitrogen, liquid argon, liquid hydrocarbons, and liquefied natural gas (LNG)). Especially with the recent development of the natural gas industry that requires clean energy, cryogenic submerged pumps have been used in a series of transportation from LNG liquefaction plants, LNG ships to LNG receiving stations.

Screw pump

    Industries: food

Screw pumps can be divided into single screw, twin screw, and multi screw, based on the number of screws. Screw pump uses the rotation of the screw to absorb and discharge liquid. The mutual engagement of the screws and the close cooperation between the screw and the inner wall of the liner will be separated into one or more sealing spaces between the suction and discharge ports of the pump. With the rotation and engagement of the screw, these sealing spaces are continuously formed at the suction end of the pump. The liquid in the suction chamber is sealed in it, and continuously pushed from the suction chamber along the screw axis to the discharge end, and the liquid enclosed in each space is continuously discharged, just as a nut is continuously pushed forward when the screw rotates. This is the basic working principle of the screw pump.

Because of the above principle, the screw pump will only change the potential energy of the fluid, but will not convert its mechanical energy into the kinetic energy of the fluid. Therefore, screw pump is an ideal choice when the process (such as food industry) requires stable conveying pressure and the inherent structure and quality of conveying medium are not damaged.
