SPECIFICATION
POSITIVE DESPLACEMENT GEAR SELF PRIMING PUMPS
MAIN APPLICATION & COMMON USE
Used to pump thick and viscous liquids without suspended solids, at low and high temperature.
Typical applications in machinery/engine lubrication, hydraulic power units, chemical additive metering, foam blending in the fire-fighting system, fuel oil supply or booster and general transfer of viscous liquids as glue, paints, grease and others.
FEATURES
The pumps in use two identical gears rotating against each other: the drive gear operates the idler gear. Liquid flows into the cavity of the teeth and is directed and pressurized toward
the discharge port by the gear rotation. Each gear is fitted on a shaft supported by two internal bushings immersed in the pumped liquid. Due to the rigidity of the shafts to the fine tolerance between rotating parts and to the improved gear profile, pumps have quiet operation and low noise balancing holes.
