1 . Screw pumps are the most widely used industrial pumps in the food industry, sugar industry, in wastewater treatment applications and especially in hydraulic presses ...

The outstanding advantage of screw pump is durable, smooth and efficient operation, but the disadvantage of this pump is that it is difficult to manufacture because of the requirement of high precision, when damaged, it is difficult to warranty and repair. Want to prolong the life of the screw pump and increase efficiency for the pump, you should put water or neutral liquid into the pump chamber after the liquid is pumped.

3 . The screw pump is one of the industrial pumps with the simplest construction of today's pumps. The main structure of a screw pump consists of the main pump body is the pump chamber, a screw pump shaft inside the pump chamber and the impeller located on the engine. The pump shaft is usually made of stainless steel or chrome steel

4 . Other parts such as output, inlet to pump liquid, seal function to seal the pump, pump base used in pump installation, electric motor and power supply to keep pump running, flexible coupling for pump flexible operation, teeth ...

In addition, the metering screw dispenser has a liquid dosing device.

Materials for manufacturing screw pumps are diversified, with cast iron body screw pump, stainless steel, plastic body, stainless steel body, ... each type has specific applications and is used for liquid pump purposes. different.

For example, the stainless steel body screw pump is suitable for use in the food industry, the plastic screw pump is suitable for pumping corrosive solid chemicals, the cast iron body screw pump is suitable for pumping super viscous substances.

Screw pumps are available in many different types and classifications depending on the needs of the user as well as the characteristics and application of the pump.

5 . Basically screw pumps include the following types of pumps:

- Screw pump horizontal / vertical body

- Single / twin / multi-twisted screw pump

- High quality screw pump / cheap screw pump

- Low capacity screw pump / screw pump

6 . Special screw pumps with high working efficiency screw pumps have the following typical applications:

- Slurry pumps

- Polymer pump

- Pumping fish oil, molasses

- Pumping fruit juice

- Pumps for waste and wastewater

- Petroleum pumps, chemical pumps

- Pumps for thickeners

Each type of screw pump has different applications and is used in different industries around the world.
