Pump Choices in Chocolate and Confectionery Processing: Lobe/CP Pumps vs. Internal Gear Pumps 

09-02-2024

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…

Pressure Relief Valves: Critical to Pump and System Safety and Reliability

01-26-2024

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…
