Product containment, especially when pumping hazardous fluids, is essential to protect the workforce and environment from dangerous leaks.
Product containment, especially when pumping hazardous fluids, is essential to protect the workforce and environment from dangerous leaks.
The effective sealing of fluid pumping equipment has always been a difficult area and is recognised as the single most common point of failure, according to Verder.
By their very nature, most seals will leak and the resulting danger, combined with the time and cost of cleaning up the resultant spillage, continue to increase.
The principle of two precision-machined surfaces being forced together and then rotated against each other whilst forming a leak free seal, has never been a reliable proposition, especially if there are solids present.
Verder has claimed to provide a solution to this problem, the TB series pump that offers a thrust free, seal free design, with the capability to handle solids.
The accepted benefits of mag drive leak free pumping have now been further developed to provide a mainstream option to traditional sealed pumps, without comprising on the more arduous applications where solids are involved.
Options exist where damage caused by dry running operation can be prevented said Verder.
The elimination of thrust represents a major step forward in enhancing trouble free, low maintenance operation: examples of maintenance free operation in excess of five years are documented for the company's mag drive series of pumps.
Incorporating hard wearing silicon carbide wear rings protects the pump from wear by solids and provides secondary back up bearings that automatically step in should there ever be a problem with the main bearing.
The Verder TB series of thrust balanced mag drive pumps features all silicon carbide shaft, bearings and renewable wear rings, as well as a zero thrust design, whilst having the claimed ability to handle fluids with entrained solids.
The TBs include a totally non-metallic wetted pump end and have a full 16-bar rated working pressure at a 121 deg C maximum working temperature.
Verder said that there is a large pump range of 1.5" to 6".
The use of silicon carbide combined with ETFE (Tefzel by Dupont) make the pumps, in their standard format, ideal for use with an array of fluids, acids, alkalis, solvents, inorganics and halogen derivatives believes the company.
That brings opportunities to build in true plant standardisation and interchangeability, with spares reduction, leading to a true reduction in the cost of ownership whilst improving plant reliability claimed Verder.
