Screw Pump



Screw Pump Manufacturer

We are Leading Manufacturer of Screw Pumps in India Screw pumps are a type of positive displacement pump that uses two or more helical rotors (screws) to move fluid through a confined space. The rotors intermesh and rotate in opposite directions, creating pockets of fluid that are trapped and moved through the pump. Screw pumps are commonly used in a variety of industrial applications, such as oil and gas, chemical processing, and food and beverage production. They are also used in marine and offshore applications, as well as in power generation and water treatment plants. Screw pumps are known for their high efficiency and ability to handle viscous liquids, as well as their ability to handle high pressure and flow rates.

Screw Pump Product Overview

APPLICATIONS SCREW PUMP The main components which characterize the pump are a metallic single helical rotary part ROTOR and fixed double helical resilient polymer part STATOR in which the rotor turns and thereby a complex progressive sealing line (cspl) is maintanined. Whilst the rotor rotates inside the stator, the cavities formed between them progresses from suction to discharge end, gently carrying the media. Liquids, have a compact space saving design and are self priming. Due to the precise manufacture of the screws and their profile, the possibility of getting a high suction lift is ensured. They operate continuously and run noiselessly
