General
The TPM sealless mag-drive turbine pumps offer high differential pressures at relatively low flow rates. Through the use of a VFD, to adjust the speed of the pump, the flow and head are easily controlled due to the steep nature of the performance curve. The ablity of the tubrine pump to handle entrained vapor makes it ideal for pumping volatile fluids near their boiling point to ensure there is no vapor lock. The hermetically sealed design of the TPM offers a superior option for flamible or toxic fluid applications.

The containment shell is designed as a pressure vessel to separate the fluid from the atmosphere. The containment shell is not used as an additional bearing holder. No dynamic stress occurs. The containment shell is bolted to the intermediate flange in a manner that allows removal of the drive end including outer magnets and ball bearings without exposing the pumped liquid to the atmosphere. Drive end bearing maintenance is possible without disturbing the system. There are three different driven end configurations. The first is a bearing bracket with greased for life bearings offered on the standard TMP. The TMPR is offered with an oil bath bearing bracket for increased bearing life. These first two options are connected to a motor through a spacer coupling. The third option is a close-coupled design. The TPMB can be mounted to a standard NEMA or IEC motor offering a smaller footprint. The wet end sleeve bearings and bushings are Silicon Carbide. A hydrodynamic force supports the shaft sleeves so there is no contact with the bushings under normal conditions. SiC is extremely hard and resistant to wear and is compatible with almost all pumped fluids. The pumps are hydraulically balanced. Any thrust loading that is seen during start-up or when conditions change is handled by SiC start-up rings that offer a counter balancing force to the thrust load when operating in the allowable range on curve. Similar to the start-up rings, the turbine impellers have stationary and rotating SiC that utilize a hydrodynamic force keeping the turbine impellers centered and preventing contact with the suction and pressure discs offering improved wet end life and reduced maintenance. |
