Swaby LOBELINE is a division of McFarland Pump Group. The LOBELINE rotary lobe pump originally developed in Canada is now a successful pump line with some interesting standard mechanical features that are only offered as options by other manufacturers such as:
- Air Gap between rotor case and the bearing housing for easy access to the seal.
- Reversible front cover plate and removable wear liners in rotor case.
- Run Dry Ability - Non contacting pumping elements allows periodic operation without fluid in the pump.
- API 676 Standard - exceeds standard with air gap, splined shafts, double taper roller bearings.
There are 8 models of pumps with 12 different sizes ranging from 30 usgpm up to 660 usgpm depending on pressure and fluid pumped.
Please contact us for more information or a quotation to suit your project needs.
