Water pumps are essential equipment in industrial production and wastewater treatment, primarily used to transport various liquids such as clean water, wastewater, chemical liquids, and high-concentration suspensions. Choosing the right type of pump for different industrial applications is crucial for improving system efficiency and reducing operational costs. Below are several common types of industrial water pumps and their characteristics.
1. Centrifugal Pump (离心泵)
Centrifugal pumps use the centrifugal force generated by the rotating impeller to transport liquids, making them suitable for high-flow, low-lift applications. They are widely used in municipal water supply, cooling circulation systems, industrial production, and wastewater treatment.
2. Sludge Pump (污泥泵)
Sludge pumps are specifically designed for transporting liquids containing solid particles or high-concentration suspensions. They are often used with screw presses, plate-and-frame filter presses, or belt-type sludge dewatering machines for sludge transportation in wastewater treatment systems. They are applied in municipal sewage treatment, food processing, petrochemical industries, and paper manufacturing wastewater treatment.
3. Screw Pump (螺桿泵)
Screw pumps use the interaction between the rotating screw rotor and stator to transport liquids. They are suitable for high-viscosity fluids and liquids containing solid particles, such as oil transportation, chemical solutions, and high-concentration sludge treatment.
4. Diaphragm Pump (隔膜泵)
Diaphragm pumps use the reciprocating motion of a diaphragm to push liquids, making them suitable for transporting highly corrosive, volatile, or high-viscosity liquids. They are widely used in chemical, pharmaceutical, food processing, and wastewater treatment industries.
5. Submersible Pump (潛水泵)
Submersible pumps integrate the motor and pump into a single unit that operates while submerged in liquid. They are suitable for low-lift, high-flow drainage applications, such as urban drainage systems, agricultural irrigation, and mine drainage.
