Pumps are important for processing dairy products ranging from milk to fruit mixes. It is vital to be able to pump the product at sufficient speed, volume and pressure while not changing its attributes. The HRS BP Series of positive displacement pumps from HRS Heat Exchangers features adjustable flow rates, ranging between 80 and 5,250 gallons per hour, as well as a high pressure drop of up to 435 psi. This makes them suitable for a wide range of high-viscosity, shear-sensitive and large-particle-containing fluids, the company says, including creams, custards, yogurts and compotes. Clap valves allow the pumping of whole fruits, further increasing flexibility.
MORE EFFICIENT PUMP
