Sealless pumps help solve sticky situation

Pumping resinous glue at high temperatures presents a sticky problem for certain types of pump, especially when there is an added complication of the glue containing particulates.

This challenging pumping application is part of the process of manufacturing Oriented Strand Board (OSB), a timber-based building product which is similar to plywood. Hydra- Cell sealless positive displacement pumps, available from Michael Smith Engineers have proved successful in this application.

The sealless design of the pumps means there are no dynamic seals to leak, wear, or replace and their springloaded, horizontal disk check valves enable the pump to process liquids which contain particulates up to 500 or greater microns in diameter without problems.

The range of Hydra-Cell pumps covers flow rates from 0.4 to 128L/min and pressures up to 172 bar, providing repeatable and accurate output.
