Complete process pump solutions for the food and beverage industry
Verder South Africa offers complete process pump solutions for the food and beverage industry , where high hygiene standards , efficiency and cost-effectiveness are critical factors .
�e food and beverage industry is one of the most important markets for Verder South Africa , points out pump specialist Kobus Fourie . High-quality production requires an environment that meets and exceeds the local hygienic requirements . Verder therefore has a wide product range to meet all the challenges in this industry .
“ Our pumps are used in the dairy industry , breweries and wineries , and a lot of other food applications . �ey pump chocolate and dough , in addition to water and CIP ( Clean-in-place ) uids . Besides our food-certi cated pumps , we also offer a lot of industry pumps with sanitary connections for less sensitive applications ,” Fourie elaborates .
Peristaltic pumps such as Verder ex are used in the animal-feeds sector to introduce additives to the mix . �e Verder ex range features peristaltic options perfect for this type of dosing , including high pressure / low ow , programmable presets , multiple-stream heads , and OEM component pumps . All models are available with FDA hose and tube types . Molasses and avourants are added to animal feed to make the mix palatable . Molasses has a viscous , syrupy and slightly oily consistency , o�en with small particulates . �is uid type is well-suited to the Verdergear internal rotary gear pump .
Carbon bushes can be speci ed if the molasses grade may cause compatibility issues . Where the sweetener is of a lower viscosity ( less than 50 cps ), such as a caramel- avour mixture , a Verder ex industrial peristaltic pump is recommended . �is provides a constant ow rate , is very low shear , and can
3 handle capacities as high as 90 m / h .
Fourie adds that Verder ex hose pumps are excellent for anaerobic digestion , which produces biogas for renewable energy . �ese hose pumps are also ideal for rotor-chopped cold organic material , warm organic material , warm slurry , waste water liquor , and enzyme and chemical solutions .
Verderhus concentric screw pumps are excellent for pumping waste with large solids such as bones . �e percentage of solid matter here can increase by up to 13 %. �ese pumps are available with sha� sealing , or in a cantilever version . �e maximum ow rate is 1
3
030 m / h . Verderpro progressing cavity pumps are ideal for pumping sh waste to produce biogas , while Verder ex Smart Pumps minimise the labour costs associated with harvesting yeast in the brewery sector . Reducing the cost of food-waste disposal into land ll is a key performance indicator for manufacturers today , which is where Verder plays an integral role as well .
Resistant to clogging even when pumping bred uids and unaffected by viscosity changes , the Verder HUS pump can handle diatomaceous earth , slurry , yeast , sugar , gelatine , hop , corn and malt , as well as agricultural waste such as chicken necks , bones , compost , biogas and pet food . In addition , abrasion is not an issue . It can also run dry without damage , whereas progressive cavity pumps and rotary lobe pumps would incur considerable damage .
�e Verder HUS centrifugal pump has fewer components , and therefore costs less than a positive displacement pump . For a given ow rate , it also has a smaller footprint . It is also more energy efficient than a positive displacement pump , using a smaller motor ( typically from 2.2 kW to 7.5 kW ). “ Verder ' s expertise lies not only in a sound understanding of pump mechanisms , but also in the process itself , including the pipework requirement to reduce or prevent blockages ,” Fourie highlights . Although a pump is a simple device with inlet and outlet connectors and a motor , a great deal of expertise is required for optimum application . “ Verder also understands process engineering , recognising that the pump itself is but part of a bigger system ,” Fourie concludes . www . farmersreviewafrica . com FARMERS [ 43 ]
