ABOUT COLFAX FLUID HANDLING
Product Portfolio: Two-Screw Pump
Two- screw pumps‚ sometimes referred to as twin-screw or twin spindle‚ were invented by William Quimby in 1894 and are manufactured by the Warren‚ Houttuin‚ and Tushaco divisions.
The fundamental concept of the two-screw pump is the use of two intermeshing screws synchronized by timing gears‚ thereby permitting the screws to convey a liquid without any metal to metal contact. This unique concept allows the pump to handle virtually any Newtonian or non-Newtonian fluid under a wide variety of conditions‚ including multiple phases (i.e.‚ gas and solids)‚ elevated temperatures and intermittent dry operation.
Two-screw pumps are used to pump the following fluids:
- Crude Oil
- Long Chain Polymers
- Chocolate
- Sea Water
- Lubricating Oils
- Adhesives
- Explosives
- Naphtha
With a capacity range of up to 12000 gpm (2750m³/hr) and pressure ranges up to 1500 psi (104 bar) the two-screw pump offers a solution to challenging applications where other positive displacement pumps cannot.
