MAINTENANCE REQUEST FORMS: PUMP REPAIR REQUEST FORM | PICKUP REQUEST FORM
Capable of tackling the most challenging high-viscosity applications, Tuthill GlobalGear® uses a robust internal gear pump design and top-quality materials to extend the pump’s life. The modular design of these pumps also decreases the usual costs needed for switching to another media, thereby also saving time and effort.
In addition, the GlobalGear® pumps are fitted with high strength parts that are easier to service and maintain than the competitor pumps.
An internal gear pump has two interlocking gears of different sizes rotating inside the other. The larger gear (the rotor) is an internal gear with the teeth projecting on the inside. A smaller external gear (the idler – only the rotor is driven) is mounted off-centre. This is designed to interlock with the rotor such that the gear teeth engage at one point.
