Overview:

Screw pumps are industrial pumps widely used in industries that require pumping high-viscosity, high-corrosion, or thick liquids. Examples include:

• Food industry: Pumping molasses in sugar production

• Wastewater treatment: Pumping sludge

• Plastics industry: Pumping polymers

Advantages:

• Durable, quiet, and efficient operation.

Disadvantages:

• Difficult to manufacture due to high precision requirements, challenging to repair or maintain when damaged.

Maintenance Recommendation:

To extend the lifespan and enhance the efficiency of screw pumps, it is recommended to flush the pump chamber with water or a neutral liquid after pumping viscous substances.
