Series D Rotary Lobe Pumps

SSP Series D ductile iron rotary lobe pumps fulfill positive transfer duties throughout industry where the use of stainless steel for pump head components is not essential, within application areas such as Petrochemicals, Chemical, Paper, Paints and Polymers, Petfood, Chocolate, Sugar and Environmental / Industrial Waste Treatment.

The Series D in standard specification has its pump casing and tri-lobe rotors manufactured from ductile iron for non-sludge applications. For sludge duties the tri-lobe rotors have a metal insert covered with either NBR or urethane, both giving long term wear resistance. The urethane rotors can be supplied slotted, providing grit channels to improve rotor life.

For increased abrasion resistance the pump head and rotors can be supplied with a tungsten carbide coating to increase wear resistance. Also pump casings can be supplied with hardened, replaceable wear plates that can be replaced in-situ with minimal pump dismantling.

Performance

The Series D pump range has nine pump head displacements ranging from 0.79 litres/rev to 6.00 litres/rev.

• Flow rates up to 180 m3/h
• Differential pressures up to 15 bar
• Port sizes from 800mm to 150mm
