Viking Pump’s new generation of internal gear pumps offer a wide array of benefits that the previous alloy pumps could not, particularly in the area of porting flexibility. These new pumps reduced the number of casing configurations, which helps reduce manufacturing complexity, cost and lead times, while at the same time increasing the number of porting options and providing greater porting flexibility.
As a masterclass in engineering design and manufacturing flexibility, Viking Pump has re-designed its heavy-duty alloy pumps, both steel and stainless steel, in the most ingenious ways. These new models reduce price and lead time by significantly reducing the number of casings and brackets for manufacturing simplification, while simultaneously providing more options for porting and shaft sealing, all while adding many great new standard features.
Unlike food processors who primarily use centrifugal pumps, chocolate and confectionery processors have two main preferences for handling viscous liquors, chocolates, sugars and other confectionery liquids: Rotary Lobe / Circumferential Piston (CP) pumps and Internal Gear Pumps. These Positive Displacement-type pumps are chosen due to various reasons. But which is best?
One of the most critical parts of any rotary pump is the shaft seal. In part 2 of our 5 part series on seals we take a closer look at Viking Pump's patented O-Pro® seal.
Greases are commonly referred to as lubricating, automotive, or bearing grease. They are generally a mixture of mineral oil with one or more metallic soaps like sodium or calcium. The texture of grease may be smooth and buttery or even fibrous or rubbery. The viscosity of greases range greatly. They are also extremely shear sensitive. Typically, flow is aided by a follower-plate on the supply tank to help maintain positive pressure on the suction side of the pump. The cast iron 1124A Series™ features Viking's O-Pro® Barrier seal - which minimizes leakage.
Out of all of the applications where you can find a Viking pump, chocolate may be the most delicious. Viking pumps are the pump of choice for the processing, transfer, and recirculation of chocolate. The chocolate production process can be simply described with these steps: cacao beans are roasted and ground, then mixed with oils into a semi-liquid. This early stage is known as "bitter" chocolate. From here, sugar can be added to make "sweet" chocolate - milk can be added for "milk" chocolate - and if the chocolate has been thinned down is called chocolate liquor.
Black liquor soap is a natural byproduct that separates from black liquor during the kraft wood pulping process used to make paper products. The soap is skimmed off and used to make tall oil. Black liquor soap can be abrasive and have varying viscosities making it a challenge to pump and seal. The cast iron 1124A Series™ features Viking Pump's O-Pro® Barrier seal, which virtually eliminates the leaking and mess associated with packed pumps. These pumps are constructed with hardened materials and have capacities up to 400 gallons per minute.
High fructose corn syrup is a product of hydrolyzed corn starch and is made up of varying ratios of glucose and fructose. High fructose corn syrup has many desirable traits - including serving as a sweetener and humectant in baking applications. When baking breads, buns, rolls, and yeast raised donuts, it ferments directly without the need for sugar inversion - the chemical conversion of saccharose into glucose and fructose. The cast iron 1224A Series™ features Viking Pump's O-Pro® Barrier seal - which prevents leakage.
Lecithin is a mixture of triglycerides, fatty acids, and carbohydrates and is typically derived from soy bean oil - but can also be obtained from egg yolks, corn, and other vegetable seeds. Lecithin ranges in viscosity up to 5,000 SSU, but may be more viscous depending on the make-up and temperature.
Lecithin has a low solubility in water which makes it an excellent emulsifying agent - allowing for its use in margarine, chocolate, and other confectionery products as a non-sticking agent.
Detergents are a blend of liquid surfactants with other powdered materials - meant to improve cleaning performance. These blends are referred to as detergent slurry. Technical elements aside, detergents can be used for many things - like cleaning laundry and dishes, removing carpet stains, stabilizing fuels, and more. The 4127C Series™ are 316 stainless steel pumps with cartridge lipseal options. They have capacities up to 320 gallons per minute. The stainless steel 1127C Series™ come with Viking Pump's own O-Pro® Guard seal which virtually eliminates leakage and is resistant to abrasives.
