Pumphead

The pump casing is manufactured in ductile iron. The Series D in standard specification has tri-lobe rotors manufactured from ductile iron (for non- sludge applications) or a metal insert covered with either NBR (which can be fitted with metal back plates for high fiber duties) or urethane, both giving long term wear resistance. The urethane rotors can be supplied slotted, providing grit channels to improve rotor life.

Shafts

Manufactured from surface hardened carbon steel.

Gearbox

The Series D pump has a robust cast iron gearbox, which provides maximum shaft rigidity. Heavy duty taper roller bearing arrangements provide maximum support for both drive and auxiliary shafts.
