EMSE gear pumps of the EDP series, depending on the material of the gear part (cast iron, stainless steel), can pump viscous liquids such as fuel oil, polyester components, caustic resin, oil, glue, mineral oil, gel, grease, chocolate, soap raw materials, glucose, quaternary esters, glycerin, rubber, wax, honey, molasses, oil and many other liquids.
The principle of operation: as a result of the rotation of the gears in constant engagement, a low and high pressure zone is formed. As a result, the fluid is drawn into the suction nozzle and, moving in the gap between the gear teeth and the housing, enters the discharge zone to the discharge nozzle.
Gear pumps are reversible and can operate in both directions. These pumps can be connected to a drive in a variety of ways. These include: direct connection to an electric motor via a coupling, connection via a gearbox, connection via a V-belt drive, connection to a variable speed drive. (This connection method allows the speed of rotation to be varied and thus the flow to be controlled.)
EDP pumps from model 1015 onwards are available with a casing with a heating jacket as standard. This feature allows for a wider range of process applications for pumping products that are prone to crystallisation at lower temperatures.
