All shafts are manufactured from AISI 316 L or Duplex sheet stainless steel. The rotors are manufactured from either high quality 316 L extruded shaped bar or in special stainless steel anti-seizure alloy CY5SnBiM. The pump body is also manufactured from AISI 316 L stainless steel and except for the B100 pump type, which is made from a sheet, all other pumps are made from the lost wax casting method.
Standard Lobe Pumps in AISI 316 stainless steel are assembled on a cast iron gear box which has a protective coating in epoxy paint finish. The chamber separating the rotor case and gear box enables the fi tting of balanced compact reversible mechanical seals, avoiding the contamination between the pumped fl uid and the gearbox lubricant.
The base of the gearbox is designed to make installation easier for connecting into horizontal and vertical pipelines. The OMAC Lobe Pump is modular in design allowing the main parts such as the rotor and seals, to be changed quickly and easily.
