Design Features
The Industrial Lobe Series pumps were designed to handle
fluids of nearly any viscosity, especially shear
sensitive materials, at higher pressures than an internal gear pump or a
standard lobe pump is capable of. The high pressure option uses a
patented shaft
support system with bushings on both sides of the bi-wing rotors to allow higher pressures and reduce wear on
bushings and seals. An adjustable bearing housing allows simple end
clearance adjustment.
These pumps accept a wide variety of cartridge-style seals
from most major manufacturers, including single mechanical, double
mechanical and triple lip seals. The two smaller sizes also accept
component single mechanical seals or shaft packing. A variety of
porting options allows the ports to be correctly sized for the
application.
