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.
