Positive Displacement Internal Gear pumping principle handles a broad range of viscosities with constant flow rate
Axial rotor thrust is controlled by double row ball bearing or tapered roller bearings; bushings provided a secondary point of radial shaft support
Rotatable bearing housing provides easy rotor end clearance adjustment to compensate for viscosity or wear
Numerous material options are available for bushings,
idler pins, shafts, rotors, idlers and elastomers
• Gear and pump geometry has been optimized based on
more than 100 years of experience
• Footed steel bracket provides rigid mounting to help
maintain alignment, which extends seal and bearing life
• Can use direct drive, gear reducer or gearmotor drive,
or belt-drive
• Pressure relief valve standard on non-jacketed pumps;
less valve / plain head option available
• Series designed with an enlarged bearing housing; used in
conjunction with a spacer coupling permits easy cartridge
seal installation and removal in place without removing the
head and rotor/shaft.
• Seal options include packing, single component seals,
cartridge lip seals and cartridge single and double
mechanical seals; various seal flush plans are available
• Steel externals for petroleum refineries, petrochemical
plants and similar customers who require higher
temperature and higher working pressures than cast iron
pumps can provide
