Many years of working with difficult heat transfer solutions in the food industry has shown us that pumping products without destroying their integrity is as important as developing heat exchange solutions which maintain product quality.

This led to the development of the HRS piston pump which can handle very delicate and viscous food stuffs. Pumping up to very high pressure without damaging the food particles is not a problem and the pump has also been applied successfully in heavy duty applications for other industries than the food industry.

Traditional pumping systems for particulate products can cause problems for food processors who needed to pump whole fruits or vegetables or pieces. Problems arise not only because of the high costs of traditional pumps, but also because lobular pumps have low flow rates. In addition, using progressive cavity pumps can break the produce, while double diaphragm pumps result in a low pressure drop.

To overcome these problems, HRS Heat Exchangers has developed a reciprocating positive-displacement pump, (the BP Series Piston Pump) that provides the following benefits:

  • Does not break or damage the product
  • Delivers high flow rates (up to 20 m³/hr)
  • Allows high-pressure drop (290 PSI)
  • Can work under vacuum
  • Is self-priming
  • Can work empty (without product)
  • Requires few spare parts
  • No seals in contact with the product.
  • Sanitary
  • Can work at high temperatures (212 °F)
  • Fewer valves per volume unit
