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?

All positive displacement pumps work by first expanding a cavity between the casing and one or more moving parts to create a partial vacuum, so atmospheric pressure can force liquid into the pumping chamber through the inlet port

Having a great product, with a great reputation, and being a technology inventor like Viking Pump®, positions you as a market leader with high visibility. As such, other internal gear pump manufacturers naturally want to follow in your footsteps. While that is a huge compliment, it also causes confusion among internal gear pump buyers.

In this article we'll walk through 5 reasons you'll want to stick with genuine Viking Pump parts and products, saving you time, money, and a headache.
