LobePros D Series 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 h5S.

All LobePro CD3mn parts are solution annealed and passivated. This is very important to obtaining the best resistance to chloride corrosion, pitting and cracking.

Reversable (can load, unload and backwash)
Strong vacuum/Self-priming to 25 feet
Handles air and fluid without damaging cavitation
Low Shear
Ability to pump thick, viscous fluids
Steady, measured flow at constant pressure
Can run dry
Handles abrasives well
