Elbow Pumps RPP/RPG The typical pump for large capacity at low discharge heads (circulation pump with axial impeller). Available in welded or cast construction with reinforcing ribs. Advantages Robust construction – long service life For abrasive fluids, Egger uses very thick blade profiles to ensure long operating times. Generously dimensioned roller bearings and a free floating Cantilever shaft without wetted bearings to ensure long service life with minimal maintenance. Gentle transport The elongated blade profile ensures low-vibration operation. Thus, the Egger Axial pumps operate very gently with sensitive crystalline fluids. Applications ·· Crystallisation plants ·· Vaporisation plants ·· Reactor loops ·· Sludge recirculation ·· Pumping stations Features ·· Thick blade profiles for long service life ·· Gentle transport with sensitive, crystalline fluids ·· Available in a wide range of metallic materials Facts & Figures Nominal dimensions: DN 250 –700 mm  10– 28", cast DN 250 –1400 mm  10– 56", welded Flow rate: up to 8300 l/s 130 000 US gpm Differential head: up to 10 m, 33 ft  Pressure: up to 6 bar, 90 psi, from DN 600 4 bar, 60 psi Temperature: up to 140 °C /  85 °F 2 Fiber repellent Fluids containing fibers tend to clog pumps quickly. Egger introduced therefore the series RPGA with specially moulded, fiber-repellent blade leading edges. Typical pumped liquids ·· Crystalline suspensions ·· Reaction mixtures ·· Concentrated acids and bases ·· Abrasive media ·· Brine and seawater ·· Fibrous media ·· Sludges and waste water Saving energy – suction behaviour Due to the systematic development of the flow geometry, our elbow propeller pumps attain an overall efficiency up to 75% and have good suction characteristics. Reliable sealing systems There is a choice of cartridge mechanical seals as well as the classical stuffing box packing. Egger axial pumps with stuffing box packing have easy-access. This allows quick replacement of the packing cords without emptying the piping nor disassembling the pump. Tough applications with corrosive fluids Egger axial pumps are designed for highly corrosive fluids and are available in a wide range of materials. The shaft is sealed from the pumped fluids. The propeller blades are welded on the hub to avoid crevice

Types of mounting Egger axial pumps are specially fabricated to customer requirements and exist in various types of mounting. They are available clockwise and counter clockwise as well as in cast or welded constructions. Special designs for temperatures up to 280 °C and pressures up to 25 bar already exist. Versions with special dimensions allow easy adaption to existing elbow systems.
