Screw Pump

BEST FOR WIDE RANGE OF LIQUIDS, FLOWS, PRESSURES & VISCOSITIES
Screw pumps belong to the rotary positive displacement group of industrial pumps.

POSITIVE DISPLACEMENT ROTARY PUMP

Screw pumps belong to the rotary positive displacement group of industrial pumps. They are equipped with one or more screws that rotate inside a cylindrical cavity. The fluid moves linearly with the immersing screws until it reaches the discharge side of the pump. The clearance between the screw and the cavity inside the casing is very tight, hence allowing the fluid to gain pressure as it travels through the pump.

The screw pump is available in a variety of different designs to satisfy the requirements of different applications.

OPERATING PRINCIPLE OF SCREW PUMPS

While there are several designs available for screw pumps, all work using the basic principle of two screws counter-rotating each other. Two screws facing opposite directions engage and create a sealed cavity with the pump casing. As fluid enters the pump through the suction side, the drive screws rotate and steadily move the fluid from the inlet to the discharge side. The pump ensures a volumetrically steady flow rate no matter the amount of pressure applied. This kind of operation makes the screw pump a better choice for handling a wide range of liquid types, flow rates, pressures, and viscosities.

SCREW PUMPS FEATURES AND BENEFITS

Ability to handle a wide range of liquids, viscosities, flow rates, and pressures
High operating efficiencies leading to low operational costs.
Smooth running components and quiet operation.
Ensures constant fluid flow even with varying system backpressures.
Less wear and tear accounts to low mechanical vibration
High tolerance to entrained air and gases.
Low pulsation, which means low stress on the fluid transfer components.
Fast to install and easy to maintain
High tolerance to contamination compared to other rotary pumps.
