Magnetically Couple
MAGNETICALLY COUPLED PRECISION PUMPS
Since 1977, Tuthill has worked to improve magnetically driven gear pumps by engineering solutions to meet the needs of varying applications and exacting designer specifications. The result is a family of magnetically coupled pumps that have found wide industry acceptance for their versatility and robust standard of build and reliability.
These pumps are known for their magnetically coupled, leak-free, seal-less construction and the non-pulsing flow of their external gear design. This makes them perfect for demanding applications such as medical equipment, laboratory equipment, chemical metering, laser cooling, and industrial temperature control. If it requires a seal free, technically advanced pump, Tuthill Magnetically Coupled Pumps are the solution.
MAGNETICALLY COUPLED EXTERNAL GEAR PUMPS
The external gear design offers flow that is relatively independent of pressure providing constant fluid delivery with no pulsations. The flow will have a controlled volume that is accurate and repeatable, making it highly suitable for metering applications. The D, T, & P Series pumps can meet these demands in circumstances with high differential pressures and high system pressures, as well as thin to moderate viscosity fluids. The high volumetric efficiency is achieved by utilizing two identical gears that rotate against each other.

 | Tuthill W Series
Details W Series Pumps
• External Gear Metering Pumps
• No Vapor Trapping Valveless Design
• Effective for metering Sodium Hypochlorite
• Metering Accuracy better than 1%
• Flow <1 ml/min to 650 GPH (2460 L/Hr)
• Differential pressures up to 250 PSI (17.2 bar)
Accuracy
Tuthill Magnetically Coupled External Gear Pumps have repeatable accuracy to better than 1% for most applications. When installed in a closed loop system with a flow meter or residual feedback, the accuracy is dependent on the flow meter or residual sensor. When installed in an open loop, the accuracy is dependent on the speed control. Typically the speed can be controlled within +/- 1 RPM.
Applications
Water and Wastewater Chemical metering such as Sodium Hypochlorite, Alums, Ferric Chloride, Hydrofluorosilicic Acid, Methanol, Polymers, Sodium Bisulfite, Sodium Hydroxide, Sulfuric Acid. |
