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.
