Product catalog summary

Applications
Gear pumps are utilized for pumping thick and viscous liquids without suspended solids across various temperatures. They are self-priming, exhibit excellent suction characteristics, and maintain a consistent flow regardless of changes in delivery pressure. Common applications include machinery lubrication, hydraulic power units, chemical additive metering, foam blending in fire-fighting systems, and transferring viscous substances like glue, paints, and grease.

Main Features
The pumps function with two identical gears rotating against each other, where the drive gear powers the idler gear. This rotation directs and pressurizes the liquid towards the discharge port. Designed for quiet operation, these pumps have low noise levels due to the rigidity of the shafts and precise tolerance between rotating parts. They are typically powered by electric motors but can also use pneumatic or hydraulic motors.

Standard Models
Standard models include a cast iron casing and cover, carbon steel shafts and gears, sinterized material internal bushings, and mechanical seals made of NBR or FPM. They also feature a built-in safety valve.

Special Models
Special models are available in materials such as bronze, stainless steel, and hastelloy, with options for soft packing seals and heating chambers.

Performance Data
The performance data table outlines specifications for various pump types, including capacity, absorbed power, and RPM, with specific values for oil viscosity of 6°E (45 cSt).

INML Gear Close Coupled Electropumps
These pumps are motor flanged and suitable for transferring liquids without solid suspensions at temperatures up to 200°C and pressures of 10 bar. They are used in applications such as transferring fuel oil to burners, loading/unloading diathermic oil, and lubricating industrial compressors and transformers.

CARATTERISTICHE COSTRUTTIVE Queste pompe usano due ingranaggi identici che ruotano l’uno contro l’altro: un ingranaggio è azionato dal motore e nella rotazione trascina l’altro ingranaggio. Il liquido riempie il volume tra i denti e viene convogliato e pressurizzato verso la bocca di mandata dalla rotazione dell’ingranaggio. Ogni ingranaggio è installato su un albero supportato da due boccole interne immerse nel liquido pompato. Grazie alla rigidità degli alberi, alla piccola tolleranza tra le parti rotanti e al proﬁlo ottimizzato dell’ingranaggio, le pompe hanno un funzionamento regolare con...
