GEHO® Heatbarrier pump
This GEHO® Heatbarrier pump is a crankshaft driven two-cylinder
double-acting and three-cylinder single-acting high temperature
piston diaphragm pumps. GEHO® pumps have gained world-wide
reputation for consistently meeting customer's requirements. The
range of Heatbarrier pumps is another example of this commitment.
The lowest possible total cost of ownership concept by means of
piston diaphragm pumps are successfully transferred to the high
temperature, extremely acid or caustic abrasive slurries feeding
into high pressure autoclave processes. The Heatbarrier pump range
is developed and manufactured by Weir Minerals Netherlands b.v.

The Heatbarrier design
handles slurry up to 210°C. A drop-leg pipe connects the valves to
the dead-headed diaphragm housing. The water jacket and oscillating
separator sustain a low diaphragm temperature (below 100°C) with
minimum heat loss. Thermal pipe expansion is not restricted, as the
pump is slide-mounted and will automatically compensate for any
temperature related expansions. A free floating separator, which
oscillates with the pump stroke speed, acts as a mechanical heat
barrier to minimize heat transfer losses and equipment sizing.
