Garbarino IN Self Priming Positive Displacement Gear Pump
The Garbarino IN positive displacement gear pump is used to pump thick and viscous fluids without suspended solids at a low and high temperature. Thanks to the volumetric effect of the gear, the IN pump is always self-priming with good suction characteristics. The Garbarino IN also has an constant flow, even if the delivery pressure changes during the operation. Internal fine tolerances makes the Garbarino IN Pump usable with only clean fluids that have lubrication properties.
Typical applications of the Garbarino IN Pump are machinery/engine lubrication, hydraulic power units, chemical additive metering, foam blending in fire-fighting system, fuel oil supply or booster and general transfer of viscous liquids such as glue, paints, grease and so on.
The Garbarino IN Gear Pump uses two indentical 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 towards 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 rigidy of the shafts, to the fine tolerance between rotating parts and to the improved gear profile, the Garbarino IN has quiet operation and low noise.
As there are no external vall bearings, the IN has only one shaft penetration through the housing, sealed with a mechanical seal. The materials of the internal parts, like the gears, shaft, gaskets and mechanical seals are selected according to the pumped fluid. The Garbarino IN is usually driven with an electric motor through elastic coupling but it is also possible to use a pneumatic or hydraulic motor.
