Proper ingredient transfer tools are crucial to maintain optimal efficiency and high product quality whilst balancing operating expenses. Food and beverage processor chips have a complicated job making buying choices when setting up new gear or upgrading out-of-date gear. A 4-ingredient recipe exists to choose the right pump technology for food and drink applications.

Food and beverage handling has no shortage of alternatives for material working. The alternatives can seem frustrating for customers, from your industry’s new twin screw pumps, the dependable rotary lobe pumping systems, the flexible electric and air-run diaphragm pumping systems, the effective piston pumping systems, and so on. There is a configuration available for sale to meet a user’s needs. These considerations will steer customers inside the right direction.

1. Flow Rate

The volume flow rate is determined by multiplying material speed and tubes size to find out gallons/liters a minute.

Determining stream rates are critical when deciding on an ideal water pump. A water pump which is not big enough for your application will run too hard or as well hot, which may result in water pump malfunction. A pump which is too large will get bigger buy and operating costs. As a general rule, pumping systems should run at 30 % to 60 % of maximum capacity. This decreases unnecessary put on because of higher speeds and provides for future growth or procedure capabilities if needed. This keeps real for rotary lobe, diaphragm, dual screw, sine pumps, and just about any other pump that may be installed in an application.

2. Product Characteristics


Fluid viscosity is the most regarding feature to water pump operators. The above mentioned flow rate overall performance ranking for pumps will decrease with material viscosity. Most pumping systems are rated for maximum flow rate with water at 1 centipoise (cP). Most food ingredients are thicker than water, decreasing maximum productivity anywhere from 5 % to over 25 percent overall performance reduction. Typically, centrifugal pumps can be used for lower viscosity fluids and pumps such as piston, lobe, diaphragm yet others are used for higher viscosity liquids.

Material viscosity will impact how well the water pump can load materials to the inlet of the water pump as well as output. Lobe pumps do not create substantial inlet suction power and also a hard time priming higher viscosity fluids. Electric or pneumatic diaphragm pumps and peristaltic pumping systems have the ability to load higher viscosity components to the pump with all the suction they create. If the material’s viscosity surpasses 100,000 cP, a ram unit will be asked to apply downwards pressure to material into the water pump when unloading from containers.


Material abrasiveness can wear out water pump elements effortlessly, particularly when using centrifugal-style pumps, that causes higher repair expenses. Material with high sugars content will quickly degrade elements when compared with other materials. Lobe pumping systems will sometimes use specialized materials and films to correctly handle this improved abrasion but can nevertheless have a problem with seeping rotary seals and rotor wear with time. Diaphragm pumping systems, which do not employ a rotary seal or revolving elements, handle abrasive components easier than the small tolerances needed in lobe pumping systems.

Material shear

In applications like tomato plants, cake fillings, ricotta cheese, meat and chicken, users should know about material shear. Diaphragm, peristaltic and sine pumps are gentle on components and definately will not shear the material becoming pumped like a centrifugal, lobe, twin screw or some other rotary-style water pump. This is very important for customers whose products are affected by shear and heat in which it can change the final product created by the equipment.

Particle size

Customers should be aware of any solids or particles within the materials becoming transferred. Food components such as salsa, fruit fillings and others have big-sized pieces of food within the fluid. Diaphragm pumps with flapper checks and peristaltic pumping systems are designed to handle solids upwards of 4-additionally in . in diameter. Rotary pumping systems can handle some solids, but not of any significant size and frequently harm particles and degrade the material because of the water pump design and operating velocity.

3. Building Materials

Ensuring the water pump components are compatible with the component becoming transmitted could keep the pumps working to get a long time. Most hygienic pumps are designed with stainless steel, but all use some sort of elastomer seals which are much more susceptible to compatibility problems. In the meat and poultry company, numerous elastomers tend not to hold up well to pet body fat and oils within the materials.

Water pump construction and elastomers should also be appropriate for the center cleaning options and clear-in-location (CIP)/clear-out-of-place (COP) specifications. Numerous problems happen each time a water pump elastomer or seal is atazyc using the food ingredient but are not able to handle the caustics employed to clear the machine.

Pump clean-capability and herb cleaning methods should be thought to pick the right pump. Does the center need a pump that is capable of doing being washed in position and never removed? This may direct customers towards rotary lobe or some other rotary pumps created for CIP capability. Diaphragm pumps can be washed in place but they are materials centered. Many vegetation are using vapor-in-place cleaning-which means all water pump elements must withstand the severe vapor temperatures operate through the pumping systems.
