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.

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.

Quats are derived from oils and fats. These raw ingredients are further processed into long chain hydrocarbons and amines - which are the building blocks of quats. Most notably used in disinfectants, quats can also be used as surfactants, in fabric softeners, and shampoo. The 4127C Series™ are stainless steel pumps with cartridge lip seal options. They have capacities up to 320 gallons per minute. The stainless steel 1127C Series™ features Viking Pump's O-Pro® Guard seal - designed for sealing abrasive liquids. They have capacities up to 320 gallons per minute.
