HRS BP Series Piston Pump

HRS Heat Exchangers has developed a pump that can handle very delicate and viscous foodstuffs without damage while working at high pressure in heavy-duty applications in the food and pharmaceutical industries.

The HRS BP Series Piston Pump is a purpose-designed reciprocating positive-displacement pump. Positive displacement pumps have an expanding cavity on the suction side of the pump and a decreasing cavity on the discharge side. Liquid flows into the pump as the cavity on the suction side expands and is expelled from the discharge side as the cavity collapses. The BP Series features a hygienic design, incorporating a separator between the piston and the hydraulic chamber, to ensure there is no contact between the product chamber and the hydraulic oil, and prevent oil from coming into contact with the product.

The pump features an adjustable flow, which can range from a minimum of 300 L/h to a maximum of 20,000 L/h, with a high-pressure drop of up to 30 bar. This makes it suitable for a range of high-viscosity fluids that are shear sensitive, which contain large particulates. Clap valves allow pumping of whole fruits or vegetables. An alternative pump with a pneumatic cylinder can be supplied for low-pressure applications of less than 5 bar.

HRS has also created the BPM Series, a mobile version of its standard BP Series pump. It is mounted on a mobile skid unit for easy movement, allowing it to be used across multiple production lines and locations. This makes it suitable for food manufacturers producing short runs of specialist products and numerous trials.
