Hygienic pumps are used in a wide range of applications and industries, including dairy, food, beverage, pharmaceutical, biotech and cosmetics. For food and beverage applications, there are a number of pump solutions available, each of which provides efficiencies and profitability to many processes, while offering reliability, hygienic safety assurance and ease of maintenance.
Recently, Jim LeClair, global product manager of Pumps and Valves with SPX Food and Beverage, provided the readers of Pumps & Systems with some tips and insights regarding the benefits of hygienic pumps:
Hygienic Positive Displacement Pumps - offer a high degree of symmetry, which provides bi-directional flow with little performance loss. The pumps’ large rotor fluid cavities and large anti-cavitation ports help to handle highly viscous fluids and large particles. They are easy to take apart and reassemble, minimizing downtime and maintenance costs.
Close-Coupled Centrifugal Pumps - offer long lifespan and, through use of a wave spring which provides more uniform loading on the seal face, the pump seal experiences less wear. The units do not require tools for disassembly, so maintenance and inspection are easier and faster, which minimizes production downtime and associated costs.
Ultra-Hygienic Centrifugal Pumps - options incorporate high efficiency impellers and have a patented spiral volute located on the pump back plate to ensure maximum efficiency and direct transfer of liquid from inlet to outlet. These pumps operate with low noise and vibration levels, while a heavy walled pump casing handles high system pressures. A number of models are available, allowing a close match to the application requirements to maximize pumping efficiency.
Hygienic Rotary Lobe Pumps - top-wing design rotary lobe pumps provide low shearing power, allowing pumping of soft and hard substances without product degradation. A top lobe design rotary lobe pump ensures gentle product handling with no risk of product entrapment, ensuring that hygiene standards are maintained. Operators will encounter fewer production interruptions when these products are used, because they have less dead spaces than other lobe pumps.
