FEATURES & BENEFITS

Ultra-hard tungsten carbide idler pin and tungsten carbide idler bushing minimize wear in this key area, since a constant supply of abrasive material is flowing through the pumping elements.
Behind-the-rotor pinned-seat mechanical seal with hard silicon carbide vs. silicon carbide seal faces, featuring external flush line from pump discharge to remove solids build-up, ensuring longest possible seal life (note: no flush line on F & FH sizes).
The grease-lubricated bracket bushing is not contacted by the pumped liquid, for long life. The pump is re-greasable, with a lip seal at the stuffing box to retain grease and a relief fitting to prevent over-greasing.
The grease-filled bracket helps to prevent air and moisture from reaching the seal faces, which helps limit crystallization of some air or water-reactive liquids.
Limiting pressure ratings helps extend pump life on abrasives, by increasing film thickness between rotating parts and reduces the loads or forces within the pump.
Limited speeds help ensure longest life by reducing fluid velocity, which reduces abrasion.
All pumped liquid is contained in the casing area, which enables superior flushing to clean the casing.
Positive Displacement Internal Gear pumping principle handles a broad range of viscosities with constant flow rate.
Footed cast iron bracket provides rigid mounting to help maintain alignment, which extends seal and bearing life.
Axial rotor thrust is controlled by double row ball or tapered roller bearings mounted in the rotatable bearing housing, which enables fast, easy end clearance adjustment.
Can use direct drive, gear reducer or gearmotor drive, or belt-drive.
Pressure relief valve is standard.
