LobePro’s D Series rotary lobe pumps are made from Type 2205 duplex steel and its cast equivalent, CD3mn for use in applications too corrosive for 316 stainless steel. These include applications with fluids containing chlorides, hydroxides, or H2S.
All LobePro CD3mn parts are solution annealed and passivated. This is very important to obtaining the best resistance to chloride corrosion, pitting and cracking.
D Series pumps can also be manufactured to meet API 676 requirements in Oil and Gas applications.
LobePro Pumps manufactures 13 rotary lobe pump models available in three series: S-Series: Sludge, Mud, and Slurries and General Use applications; C-Series: Corrosives & Chemicals; and D-Series: Duplex Pumps for Abrasives & Corrosives. Each line is also available in an API 676 Compliant version.
All are built and assembled in the USA. They guarantee shipment of wear parts within 2 working days of receiving an order or the parts are free. This applies for the first 5 years after a LobePro pump is purchased.
