B Series Lobe Pumps

The B series lobe pumps satisfy most transfer applications to suit hygienic and chemical characteristics. OMAC’S lobe pumps are appreciated all over the world for stoutness and performances, assures good services, long endurance, easy and cheap maintenance.This range consists of 16 models with deliveries from 0.05 to 200 m³/hr with the following versions available: ST Model with standard tolerances, SM Model with increased tolerances, both being made in AISI 316 stainless steel and both available with Duplex shafts. HP Model has crescent shaped rotors in anti-seizure stainless steel alloy with shafts in Duplex for counter pressures up to 20 Bar. 

The OMAC Lobe Pump is modular in design allowing the main parts such as the rotor and seals, to be changed quickly and easily. A wide range of rotors, seals and gaskets is also available. Traditional Lobe Pumps in AISI 316 stainless steel are assembled on a cast iron gear box which has a protective coating in epoxy paint finish or Nickel plated as option. The chamber separating the rotor case and gear box enables the fitting of balanced compact reversible mechanical seals, avoiding the contamination between the pumped fluid 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. Quality and high precision working is obtained through having compact and rigid mechanical parts including double conical roller bearings, shafts and oversized gears running in an oil bath within the gearbox.This is to obtain smaller tolerances as the rotors do not have any contact points. This ensures a good pump performance and reliability is obtained. A wide range of seals and gasket is available, material combination can be chosen according to the handled fluid.
