Proper ingredient transfer devices are crucial in maintaining optimal efficiency and high product quality while managing working costs. Food and beverage processor chips use a difficult task making buying choices when installing new gear or improving out-of-date equipment. A 4-component recipe is present to pick the right pump technology for food and drink applications.

Meals and beverage handling has no shortage of choices for materials pumping. The alternatives can seem overwhelming for customers, from the industry’s new dual attach pumps, the reliable rotary lobe pumping systems, the flexible electric and air-operated diaphragm pumping systems, the effective piston pumps, and so on. There is a settings available in the market to satisfy a user’s needs. The following considerations will steer customers inside the right path.

1. Stream Rate

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

Determining stream rates are essential in selecting the ideal pump. A pump which is too small for your application will run too hard or too hot, which may cause water pump failure. A pump which is too big will get bigger purchase and working expenses. As a general rule, pumps ought to operate at 30 % to 60 % of optimum capacity. This decreases unneeded put on due to high speeds and enables long term growth or process abilities if needed. This keeps real for rotary lobe, diaphragm, twin screw, sine pumping systems, and just about any other water pump that may be placed in an application.

2. Product Qualities


Liquid viscosity is easily the most concerning feature to water pump operators. The aforementioned stream rate overall performance rating for pumps will reduce with materials viscosity. Most pumps are rated for maximum stream price with water at 1 centipoise (cP). Most food ingredients are heavier than water, reducing maximum output anywhere from 5 % to upwards of 25 percent overall performance reduction. Typically, centrifugal pumping systems can be used as lower viscosity fluids and pumps such as piston, lobe, diaphragm as well as others can be used as higher viscosity liquids.

Material viscosity will impact how well the pump can load materials into the inlet of the pump as well as productivity. Lobe pumping systems usually do not create substantial inlet suction power and also have a tough time priming greater viscosity fluids. Electric or pneumatic diaphragm pumps and peristaltic pumps are able to load high viscosity components to the water pump with the suction they produce. In the event the material’s viscosity surpasses 100,000 cP, a ram unit will be required to apply downwards pressure to material to the pump when unloading from containers.


Materials abrasiveness can break down water pump elements easily, particularly when using centrifugal-style pumps, which in turn causes higher repair costs. Materials with higher sugar content will quickly wear out elements when compared with other materials. Lobe pumping systems will sometimes use specialized components and coatings to properly handle this improved abrasion but can nevertheless struggle with leaking rotary seals and rotor put on as time passes. Diaphragm pumping systems, which do not employ a rotary seal or rotating components, handle harsh materials much easier compared to tight tolerances needed in lobe pumping systems.

Materials shear

In applications like tomatoes, cake tooth fillings, ricotta cheeses, meat and poultry, customers should know about materials shear. Diaphragm, peristaltic and sine pumps are mild on components and definately will not shear the content becoming pumped like a centrifugal, lobe, dual attach or some other rotary-design water pump. This is important for customers whose products are influenced by shear as well as heat where it can alter the final product produced by the equipment.

Particle dimension

Customers should be aware of any solids or contaminants inside the materials becoming transmitted. Meals ingredients like salsa, fresh fruit fillings yet others have large-size bits of food inside the fluid. Diaphragm pumps with flapper inspections and peristaltic pumps are made to handle solids upward of 4-plus in . in diameter. Rotary pumps can handle some solids, although not of the significant dimension and quite often damage particles and degrade the content as a result of water pump design and operating speed.

3. Building Materials

Ensuring the pump materials are appropriate for the ingredient becoming transmitted can keep the pumps working for a long time. Most hygienic pumps are built with stainless steel, but all use some type of elastomer closes which are much more prone to compatibility problems. Inside the meats and chicken company, many elastomers usually do not hold up well to pet body fat and oils inside the material.

Pump construction and elastomers also need to be appropriate for the facility cleaning solutions and clean-in-place (CIP)/clear-out-of-place (COP) requirements. Many faults occur when a pump elastomer or seal is atazyc with the meals component but are not able to handle the caustics utilized to clear the gear.

Pump clear-capability and plant cleaning procedures has to be thought to choose the right water pump. Does the facility demand a water pump that can do becoming cleaned set up rather than removed? This may direct customers towards rotary lobe or any other rotary pumping systems intended for CIP ability. Diaphragm pumping systems can be washed in position but are materials centered. Many plants are utilizing vapor-in-location cleaning-meaning all water pump elements should endure the extreme steam temperature ranges run with the pumps.
