In these systems, plant engineers and managers use pumps to move product through the process pipelines, to empty or fill storage tanks or vessels, and in clean-in-place (CIP) operations to pump rinse and cleaning solutions through the processing system to thoroughly clean it, and ensure that it continues to meet hygienic standards.To get more news about Single Screw Pumps, you can visit hw-screwpump.com official website.

CSI represents several different pump suppliers and uses their products in the sanitary processing systems that we design, build, and install for our customers.

This article will give you an overview of the OS Series Twin Screw pump from Alfa Laval to help you determine when to specify this CIP and product transfer pump.

The following paragraphs will review what a screw pump is, how it is used in sanitary processing applications, and the unique features and benefits of the Alfa Laval Twin Screw pump.
ADVANTAGES
In comparison to centrifugal pumps (which use impellers to move water or other fluids through the pump), positive-displacement screw pumps offer several advantages:

The pumped fluid is moved axially, reducing turbulence and pulsation resulting in very low damage to pumped product. This design feature makes these types of pumps easier on product than centrifugal-style pumps.
Screw pumps can pump fluids of significantly higher viscosity than centrifugal pumps.
Changes in pressure differential have little impact on the flow rate of positive-displacement pumps compared to centrifugal pumps when pumping viscous product.
DISADVANTAGES
In comparison to other types of pumps, however, twin screw pumps have a couple of disadvantages:

Twin screw pumps are relatively expensive to purchase. In applications where a diaphragm or lobe-type pump is already working well, a twin screw pump is not a cost-effective solution.
To accommodate both process and CIP applications, twin screw pumps need to use larger motors than other types of pumps. A good rule of thumb for sizing a twin screw pump for a dual-use application is to use the same horsepower motor as one would use for a CIP supply pump.
Due to their complexity compared to other types of pumps, twin screw pumps may have additional maintenance requirements.
