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.
