Proper ingredient transfer tools are vital in maintaining ideal efficiency and high product quality whilst managing operating costs. Food and beverage processor chips have a difficult task creating buying choices when installing new equipment or improving outdated equipment. A 4-ingredient formula is present to select the right pump technology for food and beverage applications.

Food and beverage handling has no shortage of options for materials pumping. The options can seem overwhelming for customers, from your industry’s new twin screw pumps, the reliable rotary lobe pumping systems, the flexible electrical and air-run diaphragm pumps, the powerful piston pumps, etc. There is a settings available for sale to fulfill a user’s requirements. The subsequent considerations will steer customers in the right path.

1. Stream Price

The volume stream price is determined by multiplying materials speed and tubing size to determine gallons/liters per minute.

Determining flow rate is critical in selecting the ideal water pump. A pump that is certainly too small for that application will operate as well hard or as well hot, which may cause water pump failure. A pump that is certainly too big will get larger purchase and working costs. As a general rule, pumping systems should run at 30 % to 60 % of maximum capacity. This decreases unnecessary wear as a result of higher rates of speed and allows for long term growth or procedure capabilities if necessary. This keeps real for rotary lobe, diaphragm, dual screw, sine pumps, and just about some other water pump that may be placed in an application.

2. Product Characteristics

Viscosity

Liquid viscosity is regarded as the regarding characteristic to water pump operators. The above mentioned flow price overall performance ranking for pumping systems will reduce with materials viscosity. Most pumping systems are ranked for max flow rate with water at 1 centipoise (cP). Most meals components are thicker than water, reducing maximum output from 5 % to over 25 percent performance reduction. Usually, centrifugal pumps are used for lower viscosity fluids and pumping systems like piston, lobe, diaphragm and others can be used for higher viscosity fluids.

Material viscosity will affect how well the water pump can load material to the inlet from the pump as well as productivity. Lobe pumping systems do not produce significant inlet suction and also have a difficult time priming higher viscosity liquids. Electrical or pneumatic diaphragm pumping systems and peristaltic pumping systems are able to load high viscosity components in to the water pump using the suction they create. In the event the material’s viscosity exceeds 100,000 cP, a ram device will be required to use downward stress to material to the water pump when unloading from containers.

Abrasion

Materials abrasiveness can break down water pump elements easily, particularly when utilizing centrifugal-design pumping systems, that causes higher repair costs. Materials with higher sugar content will quickly degrade elements when compared with other materials. Lobe pumping systems will occasionally use specialized components and coatings to correctly handle this improved abrasion but can nevertheless have a problem with leaking rotary seals and rotor put on with time. Diaphragm pumps, which do not employ a rotary seal or revolving elements, handle harsh materials easier compared to small tolerances required in lobe pumping systems.

Material shear

In applications like tomatoes, cake fillings, ricotta cheese, meats and chicken, users should know about material shear. Diaphragm, peristaltic and sine pumping systems are mild on materials and can not shear the fabric being pumped like a centrifugal, lobe, dual attach or any other rotary-style water pump. This is important for users whose products suffer from shear and also heat where it can change the final item created by the equipment.

Particle dimension

Users should be aware of any solids or particles inside the materials becoming transferred. Food components including salsa, fresh fruit fillings yet others have big-sized pieces of meals in the liquid. Diaphragm pumping systems with flapper inspections and peristaltic pumping systems are created to handle solids upwards of 4-additionally inches in diameter. Rotary pumping systems can handle some solids, although not of the significant dimension and frequently harm particles and degrade the material as a result of pump style and working speed.

3. Construction Materials

Guaranteeing the water pump materials are compatible with the ingredient becoming transmitted can keep the pumping systems operating for a long time. Most hygienic pumping systems are built with stainless, but all use some kind of elastomer seals that are much more vunerable to compatibility problems. Inside the meat and chicken company, numerous elastomers usually do not hold up well to animal body fat and oils within the material.

Water pump construction and elastomers should also be suitable for the center cleaning solutions and clean-in-place (CIP)/clean-out-of-place (COP) requirements. Numerous faults occur whenever a water pump elastomer or seal is atazyc using the meals component but cannot handle the caustics used to clean the gear.

Pump clear-ability and plant cleaning procedures has to be shown to select the right pump. Does the facility need a water pump that is capable of becoming washed in place and not removed? This may direct customers toward rotary lobe or some other rotary pumps intended for CIP capability. Diaphragm pumping systems can be cleaned in position but are materials dependent. Many vegetation are now utilizing vapor-in-place cleaning-which means all water pump components should withstand the extreme vapor temperatures run through the pumps.
