FOOD PROCESS
Gemstone introduced the first Hydro-Transport food process pump to the industry almost 40 years ago, and has maintained its reputation ever since with pumps that can transport a wide range of food items – from potatoes to tomatoes – with minimal damage.
In addition to the P and PP series pumps, many other Gemstones are used in the food industry for applications such as waste water, hot oil, and clear liquids.
Food Process pumps use bearing frames with the instantly recognizable design incorporating mounting surfaces rather than mounting feet, letting you know it’s a quality Gemstone frame supporting a robust Gemstone at just a glance.

In addition to the P and PP series pumps, many other Gemstones are used in the food industry for applications such as waste water, hot oil, and clear liquids.
Cortex Heat Oil Pumps
Gemstone ’s cortex heat oil pumps offer enhanced vapor handling to prevent entrained steam from impacting pump head and flow. When fresh product passes through the fryers a great deal of water is released. The water travels along the bottom of the fryer, intact in a liquid phase at 200°C, until it reaches the pump suction. Here the action of the impeller breaks up the water into smaller droplets which flash to steam. Ordinarily, this entrained steam would severely impact pump head and flow, but this impact is mitigated by Gemstone ’s innovative vapor suppression line.
