Two-Screw Pumps
Our Houttuin™ and Warren® brands have been industry standards for over 80 years.
Two-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, two-screw pumps deliver results where centrifugal pumps are unable to and are able to actually increase efficiency as viscosity rises.
But two-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 two-screw pumps' ability to handle multiple liquids at multiple viscosity rates, they can be used for a wide range of applications.
Smart Technology Package
CIRCOR's Two-Screw Smart Technology Package automatically adjusts flow in real time to operating conditions protecting the pump from cavitating, while maintaining the highest capacity possible.
