Proper ingredient transfer tools are crucial in maintaining ideal efficiency and high product quality while balancing working expenses. Food and beverage processors use a difficult job making buying choices when installing new gear or improving outdated gear. A 4-ingredient recipe exists to choose the right water pump technology for food and beverage applications.

Food and beverage processing has an abundance of choices for materials working. The options can seem overwhelming for users, through the industry’s new twin attach pumps, the reliable rotary lobe pumping systems, the flexible electrical and air-operated diaphragm pumping systems, the powerful piston pumps, and so on. There is a settings available in the market to meet a user’s requirements. The subsequent considerations will steer customers inside the right path.

1. Stream Price

The volume stream rate is dependent upon multiplying material velocity and tubing size to determine gallons/liters each minute.

Determining stream rates are critical when deciding on the perfect pump. A pump which is not big enough for that application will operate as well hard or as well hot, which may result in water pump failure. A pump which is too big will incur larger buy and operating expenses. As being a general principle, pumps should operate at 30 percent to 60 percent of optimum capability. This decreases unnecessary wear as a result of higher speeds and provides for future expansion or procedure capabilities if necessary. This holds real for rotary lobe, diaphragm, dual attach, sine pumping systems, and just about some other pump that may be set up in an application.

2. Product Characteristics


Fluid viscosity is the most concerning feature to pump operators. The aforementioned flow rate overall performance ranking for pumping systems will reduce with materials viscosity. Most pumps are ranked for optimum stream rate with water at 1 centipoise (cP). Most food components are thicker than water, reducing optimum productivity anywhere from 5 % to over 25 percent performance reduction. Usually, centrifugal pumps can be used for lower viscosity liquids and pumps including piston, lobe, diaphragm yet others can be used for higher viscosity liquids.

Material viscosity will impact how well the water pump can load material to the inlet in the water pump as well as output. Lobe pumps tend not to create significant inlet suction and have a difficult time priming higher viscosity fluids. Electrical or pneumatic diaphragm pumping systems and peristaltic pumping systems are able to load high viscosity materials in to the pump using the suction power they create. In the event the material’s viscosity surpasses 100,000 cP, a ram unit will be required to apply downwards stress to material to the pump when unloading from storage containers.


Materials abrasiveness can wear out water pump elements easily, especially when utilizing centrifugal-style pumping systems, that causes greater repair costs. Materials rich in sugars content will rapidly wear out components compared to other materials. Lobe pumps will occasionally use specialty materials and coatings to properly handle this increased abrasion but can still have a problem with leaking rotary closes and rotor put on over time. Diaphragm pumping systems, which usually do not employ a rotary seal or rotating elements, handle abrasive materials much simpler than the tight tolerances required in lobe pumps.

Material shear

In programs like tomato plants, pie tooth fillings, ricotta cheeses, meat and chicken, customers should know about material shear. Diaphragm, peristaltic and sine pumping systems are mild on components and will not shear the content becoming pumped like a centrifugal, lobe, twin screw or some other rotary-design pump. This will be significant for users in whose products suffer from shear and heat where it can alter the final product made by the gear.

Particle size

Customers should know about any solids or contaminants inside the materials being transferred. Food components like salsa, fruit tooth fillings as well as others have big-size bits of meals inside the liquid. Diaphragm pumping systems with flapper checks and peristaltic pumping systems are created to handle solids upwards of 4-additionally in . in size. Rotary pumps can handle some solids, however, not of the significant size and frequently damage contaminants and degrade the content because of the pump style and working velocity.

3. Building Materials

Ensuring the pump materials are appropriate for the component becoming transferred can keep the pumps working for any long time. Most hygienic pumping systems are built with stainless-steel, but all use some type of elastomer closes which can be much more susceptible to compatibility issues. In the meat and poultry company, many elastomers tend not to hold up well to animal fats and oils in the materials.

Water pump construction and elastomers also have to be suitable for the facility cleaning options and clear-in-location (CIP)/clear-out-of-place (COP) requirements. Numerous problems occur when a water pump elastomer or seal is atazyc with the food component but cannot handle the caustics used to clear the gear.

Water pump clean-capability and plant cleaning methods has to be thought to select the right pump. Does the facility require a water pump that is capable of becoming cleaned set up and never eliminated? This may direct users towards rotary lobe or any other rotary pumps designed for CIP ability. Diaphragm pumps can be washed set up but they are material dependent. Many vegetation are utilizing steam-in-location cleaning-meaning all water pump components must endure the extreme steam temperature ranges operate with the pumps.
