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…

A key advantage of rotary positive displacement pumps is providing consistent flow regardless of changes in liquid viscosity or differential pressure. But should a downstream blockage occur, pressure will rapidly build and may exceed the rating of the pump, drive equipment, system, or any combination thereof, with the potential for damage and unplanned downtime. For this reason, overpressure…

With Viking pumps the answer is usually “yes,” but before you turn that “reverse” switch on your pump’s motor starter or variable frequency drive, there are a number of things to consider, which are discussed here

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
