Proper ingredient transfer devices are vital to maintain ideal efficiency and high product quality while balancing operating costs. Food and beverage processor chips possess a difficult job creating buying decisions when installing new gear or improving out-of-date equipment. A four-component recipe exists to select the right pump technology for food and drink applications.

Meals and drink handling has an abundance of options for material pumping. The choices can seem frustrating for users, through the industry’s new dual screw pumping systems, the dependable rotary lobe pumps, the flexible electrical and air-operated diaphragm pumping systems, the powerful piston pumping systems, etc. There is a configuration available in the market to fulfill a user’s needs. These considerations will steer customers inside the right direction.

1. Stream Price

The volume flow price is determined by multiplying materials velocity and tubing dimension to determine gallons/liters a minute.

Determining flow rates are critical when deciding on the perfect pump. A pump that is too small for the application will operate as well hard or too hot, which may cause water pump malfunction. A water pump that is certainly too big will incur bigger buy and operating costs. Being a general principle, pumps should operate at 30 percent to 60 % of maximum capability. This reduces unneeded put on because of high rates of speed and provides for future growth or process capabilities if required. This holds real for rotary lobe, diaphragm, twin screw, sine pumping systems, and just about some other pump that may be set up in an application.

2. Product Characteristics


Fluid viscosity is regarded as the concerning feature to water pump operators. The above mentioned flow rate performance rating for pumping systems will decrease with materials viscosity. Most pumping systems are rated for max flow price with water at 1 centipoise (cP). Most food components are thicker than water, decreasing optimum productivity from 5 percent to in excess of 25 % overall performance decrease. Usually, centrifugal pumps can be used for lower viscosity fluids and pumping systems like piston, lobe, diaphragm and others can be used as greater viscosity liquids.

Material viscosity will affect how well the pump can load materials in to the inlet from the water pump as well as productivity. Lobe pumps tend not to create significant inlet suction power and have a difficult time priming higher viscosity liquids. Electrical or pneumatic diaphragm pumps and peristaltic pumps are able to load high viscosity materials to the pump with all the suction they create. In the event the material’s viscosity exceeds 100,000 cP, a ram device will be asked to use downward stress to materials to the water pump when unloading from storage containers.


Materials abrasiveness can break down water pump components easily, specially when using centrifugal-design pumps, which causes greater repair costs. Material rich in sugars content will quickly wear out elements in comparison to many other materials. Lobe pumping systems will occasionally use specialized components and coatings to correctly handle this improved abrasion but can still have a problem with leaking rotary closes and rotor put on as time passes. Diaphragm pumping systems, which do not employ a rotary seal or rotating elements, handle harsh components easier compared to tight tolerances required in lobe pumps.

Material shear

In applications like tomatoes, pie tooth fillings, ricotta cheeses, meat and chicken, customers should know about material shear. Diaphragm, peristaltic and sine pumps are mild on components and can not shear the fabric being motivated like a centrifugal, lobe, twin attach or any other rotary-design pump. This will be significant for users in whose items are affected by shear as well as heat where it can alter the last product produced by the machine.

Particle size

Users should be aware of any solids or contaminants in the materials being transferred. Meals components including salsa, fruit tooth fillings as well as others have big-size items of food within the fluid. Diaphragm pumping systems with flapper inspections and peristaltic pumps are made to handle solids upward of 4-additionally in . in size. Rotary pumping systems can handle some solids, although not for any significant size and quite often harm particles and degrade the content as a result of pump style and working velocity.

3. Building Materials

Ensuring the pump materials are compatible with the component being transmitted will keep the pumps operating for any long time. Most hygienic pumping systems are built with stainless-steel, but all use some type of elastomer seals which are much more susceptible to compatibility issues. Within the meat and poultry business, many elastomers usually do not hold up well to animal fats and oils in the materials.

Water pump construction and elastomers also have to be appropriate for the facility cleaning solutions and clear-in-place (CIP)/clean-out-of-location (COP) specifications. Many problems happen whenever a pump elastomer or seal is atazyc with the food component but cannot handle the caustics utilized to clear the gear.

Pump clean-capability and herb cleaning procedures must be considered to pick the right water pump. Does the center need a water pump that is capable of doing becoming cleaned set up and not eliminated? This may direct users toward rotary lobe or any other rotary pumps intended for CIP capability. Diaphragm pumps can be washed in position but they are material dependent. Numerous plants are utilizing steam-in-place cleaning-which means all pump elements must endure the severe steam temperatures operate from the pumping systems.
