The YK series of Internal Eccentric Gear Pump are designed for the pumping of low to high viscosity fluids with lubricating properties. Available with and without an external bypass relief valve, these gear pumps are also available with an external heating jacket to prolong the temperature of the medium being pumped. The clearance between the gears is tight and therefore means that these eccentric gear pumps are unable to pump fluids containing abrasive particles. Common uses for these internal gear pumps include fuel oil transfer, diesel fuel transfer, coolant transfer, OEM, hot oil circulation, food industry, marine, detergent industry and lubrication.

FAQs

Gear pumps operate by an unchanging volume of fluid passing between the teeth of two meshing gears and their casing at a constant rate (not between the gears themselves). As the gears rotate and the meshed teeth separate, a partial vacuum is formed that fills with fluid, which they trap and move it around the casing from the suction to the discharge point.

The pumping of high viscosity lubricating fluids such as oils, fuels, paints, soaps and resins. The pumping of low viscosity fluids should be avoided as they can cause fluid to leak backwards or "slip" back to the suction side.

An internal gear pump operates a "gear within a gear" principle, whereby one gear (the idler) is positioned inside another gear (the rotor).

Whilst external gear pumps offer higher pressure and flow rates, internal gear pumps generally have better suction capabilities and are able to handle higher temperature, higher viscosity fluids. Internal gear pumps slower speeds and larger clearances also makes them more suitable for shear sensitive fluids

Yes. Gear pumps have excellent self-priming capabilities thanks to their rotating gears evacuating any air in the suction line, and forcing the liquid into the pump inlet.

The close tolerances between the gears and casing mean that pumping solids will result in wear and damage. Some internal gear pump designs which have less tight tolerances and slower speeds however may be able to tolerate small solids.
