PB pump Series was designed for low capacity (from 3 Ipm) and low pressure {16/40bar) services. Fluids normally used are Diesel Oil, LSMGO, Fuel Oil forBoiler/ Bumerfeeding and Lubricant Oil, Mineral Oil forsmall lube and pre-lube system Like ali the other SEIM pumps series, PB series is designed to satisfy customer needs also in terms of !ow maintenance cost and long iifeofthe internal parts of the pump. Every choice taken during the PB pump project, like material or components to be used, like surface treatmentand hardening, dimension, tolerance and surface roughnessand machining, is...

Main characteristics of this pump series are: - Compact shape - Same casingforthe two sizes - Standard flange connection (SAE) - High quality mechanical Seals -Casing material: UNI EN 1563GJS400 Nodular Cast Iron - Screw material: Nitrided Steel -Version coupled with Magnetic Drive - Pumps used forSEIM SPB double pump station for Boiler/Burner
