Pumping of oil at constant flow in lubrication systems and circulation of cooling fluids.
\nControlled transfer of chemical liquids (acids, bases, solvents).
\nPumping of liquid fuels such as diesel, gasoline and biodiesel.
\nTransfer of resins, solvents and pigments.
\nConveying of mineral oils or high viscosity liquids.
\nDosing of cosmetic products such as creams and lotions.<\/p>\n

Materials.<\/strong><\/p>\n

Pump cover and casing: Bronze, Cast Iron, Ductile Iron, Cast Steel, Stainless Steel AISI 316 – AISI 316L. Also in exotic materials.
\nGears: Bronze, Ductile iron, cast iron, cast steel, stainless steel AISI 316 – AISI 316L. Also in exotic materials.
\nBushings: Bronze, carbon graphite, tungsten carbide, ball bearings
\nSeals: Packing gland, mechanical seal, special closed system, cartridge mechanical seal. <\/p>\n

Optional with magnetic coupling<\/strong><\/p>\n

The picture shows the liquid filling the suction port and the spaces between the gear teeth. The black arrows indicate the direction of rotation and fluid feed. <\/p>\n

As shown, liquid transfer is accomplished by the housing and the gears inside the housing. The liquid does not pass between the gears. <\/p>\n

This picture shows the situation inside the liquid filling pump, just before it passes into the discharge area. Note how the drive and driven gears ensure volume control and an enclosed area for the liquid. <\/p>\n

 <\/p>\n

The image shows the process of discharging and advancing the liquid. The pressure generated by the gear drives the liquid to the outlet port. <\/p>\n
