The TB Series From All Pumps Supplies can handle slurries with solids concentrations of up to 30% and particle sizes to 6mm in size are possible.
TB Series Techniflo Mag Drive Centrifugal Pump clearance rings restrict solids greater than 0.1mm from entering the containment shell area, keeping all bearings and critical flow paths clear. This enables the centrifugal pump to successfully handle solids.
Solids enter the centrifugal pump through the suction and pass out through the discharge nozzle. Some of the solids will try to leak around the impeller past the wear rings. The leakage past the front wear rings simply returns the particles directly to the suction flow.
However, leakage past the back wear rings could bring particles in contact with the inner magnets, the containment shell and the radial bearings. Fortunately, wear rings restrict solids > 0.005” from entering the containment shell area, keeping all bearings and critical flow paths clear. No other non metallic mag-drive keeps the solids from entering these critical areas behind the impeller.
The TB series Magnetic drive centrifugal pump has a zero balanced thrust design and hence no internal thrust bearings, eliminating any internal high force areas where solids can abrade the pump. The rear of the pump is further protected by a self contained rotary filter that ensures that all solids are contained in the impeller end of the pump and are quickly dissipated through the discharge.
Low NPSH Requirement - The centrifugal pumps are highly efficient and have exceptionally low NPSH requirements giving a stable hydraulic platform that can cover a wide range of process demands.
Chemically Inert Materials - The Techniflo TB shaft and bearings are manufactured only in silicon carbide, the temperature gradient of this material is slower on the build up and quicker on dissipation than ceramic making the pump very forgiving and tolerant of any intermittent short term dry running.
