Many types of pump are suitable for use in the food industry, including rotary lobe, rotary piston, reciprocating positive displacement, progressing cavity, peristaltic hose and air-operated double diaphragm designs. However, traditional pumps can be expensive to maintain while lobular pumps have low flow rates. In addition, using progressive cavity pumps can break the product, while double diaphragm pumps result in a low pressure drop.
Having seen the results of using the wrong pump for the wrong job, HRS went back to the drawing board to develop a pump which could handle very delicate and viscous food stuffs without damage while working at high pressure in heavy duty applications in the food and pharmaceutical industries. The result was a purpose designed reciprocating positive-displacement pump: the HRS BP Series Piston Pump.
