Rogers Engineered Internal Gear Pump System (RPS.IG)
Internal gear pumps are best used for pumping viscous, non-water-like liquids and are one of the oldest varieties of pumps still used in industry. They are incredibly versatile and can range in size from 8 GPM to greater than 1500 GPM and up to 200 PSIG discharge pressures.
Internal gear pumps are positive displacement type which means for every rotation they pull in a fixed volume of pumping liquid. They can be ran fast or slow depending on the application and can be fixed speed or variable speed to maintain a specific discharge pressure.
Internal gear pumps come in a variety of materials of construction such as cast iron, steel, stainless steel, or even some specialty metals. They can have packing seals, lip or mechanical seals, O-ring seals, or even be completely sealed and driven by magnetic couplings for extremely hazardous or caustic applications where the liquid cannot be exposed to the atmosphere.
Internal gear pumps are incredibly flexible in their applications with flexible porting arrangements, can be rotated forward or backward, have limited dry priming capability, and can be a direct-driven belt drive or reducer driven for even slower speeds. Internal pressure relief valves are also commonly used to prevent overpressurizing the discharge lines and internally circulate the pumping liquid.
