Pump improves efficiency and reduces energy costs

17 December 2009

AxFlow is assisting companies within the UK chemical processing industries to reduce their energy costs and improve efficiency in fluid transfer applications by introducing them to the benefits of the Blackmer ProVane motor speed pump.

The pump employs a hydrodynamic journal bearing that reduces shaft/bearing contact and minimises friction, which in turn leads to higher mechanical efficiency and energy savings. When in operation the hydrodynamic journal bearing eliminates contact between the shaft and the bearing in the pump by hydroplaning above the bearing surface on a cushion of liquid.

In this hydrodynamic condition metal-metal contact or wear is eliminated so the bearing life becomes indefinite. The Blackmer ProVane has been engineered to achieve hydrodynamic mode, the point at which the liquid film delivers the lowest bearing friction and least wear, in the shortest possible time in order to preserve the life of the bearing. In this respect, it is quite simply the fastest pump in its class. The pump also maintains the optimum bearing characteristics even under a wide range of operating conditions within many chemical processing and transfer applications.

The pump’s vane technology principle give it a superior performance even after a significant period of operation and removes the efficiency-robbing ‘slip’ that may occur with other types of pump. The ProVane delivers operating speeds up to 3,600rpm and capacities up to 379lt/min in port sizes ranging from 20mm to 50mm.
