This GEHO® Heatbarrier pump is a crankshaft driven two-cylinder double-acting and three-cylinder single-acting high temperature piston diaphragm pump. This range is specially designed for feeding high temperature, acid or caustic abrasive slurries into high pressure autoclave processes.
Key features/benefits
Designed for pumping solids/liquid mixtures and high pressures/high heads
Heavy duty industrial pump
Diaphragm protects piston and liner from contact with abrasive slurry
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
Free floating separator, which oscillates with the pump stroke speed, acting as mechanical heat barrier to minimize heat transfer losses and equipment sizing
High availability; continuous duty 24/7
Low energy consumption due to very high efficiency from 85 to 95%
Low carbon footprint because of low energy consumption
Long maintenance intervals
High MTBF
Low operating costs
No external water flushing required
