TWIN-SCREW PUMPS

Our Houttuin and Warren® brands have been industry standards for over 80 years.

Twin-screw pumps are delivering results in even the toughest of conditions all over the world.

And no one knows this technology like CIRCOR.

High performance meets high reliability.

Because they're designed to move fluid at a consistent rate, regardless of pressure, twin-screw pumps deliver results where centrifugal pumps are unable to and are able to actually increase efficiency as viscosity rises.

But twin-screw pumps don't just offer performance, since they are designed to eliminate metal-on-metal contact which means a longer life, improved reliability and less downtime.

In addition, unlike other pump options, two-screw pumps can:

- Tolerate contamination
- Handle a large range of viscosities and fluids
- Low NPSH required
- Run dry
- Low fluid sheer
- Operate at variable speeds

And with twin-screw pumps' ability to handle multiple liquids at multiple viscosity rates, they can be used for a wide range of applications.

Case Study

Keeping the Lights On: Performance Insurance for Mission Critical Pumps in A Peaking Power Plant

Just because a twin-screw fuel pump is more than 40 years old and has never seen a doctor doesn’t mean it shouldn’t. Read our new case study to find out how a primary supplier of backup electrical power benefited from a comprehensive health check performed by a CIRCOR authorized service center on two mission critical pumps. When they learned the pumps were operating well outside the factory clearances and design tolerances the equipment was built for, there were decisions to make.
