Has with the single-stage series MTA Grundfos the series for the dirty media evolved: Used as a return pump, it promotes with chips from the machining and other abrasive substances contaminated coolants. She masters particles and chips up to a diameter of 10 mm.
The system used in this series, semi-open impeller resists abrasive solids, is corrosion resistant and promotes viscous media up 75 cSt, without overloading the engine. As has been omitted on the installation of a constructive Wellendabdichtung which pumps type MTA are absolutely dry running and maintenance.
In addition, the machine tool manufacturer to choose how the coolant is drawn. Usually, the coolant is at sump pumps sucked from below ('Bottom Suction'). As an option, the MTA sucking on a rotated 180 ° impeller from above ('Top suction'). The optional design requires no ground clearance, and floating chips can be drawn easily.
With nine sizes and variants 100 covers the MTA series the power range up 350 l / min and heads off to 18 m. MTA pumps are equipped with the highest electrical and hydraulic efficiency, which saves energy and reduces heat transfer to the coolant. The lower heat input reduces the cooling power to be applied and thus reduces the operating costs.
For the international machine tool manufacturer is important that the five engine sizes bifrequent for operation with 50 and 60 Hz are designed and fulfilled in three different voltage variants for markets in Europe, Asia and the U.S. as well stehen.Darüber, the most powerful pump MTA200 with the international standards for motor IE3 highly efficient engines, including the. since 16 June overarching European Ecodesign Directive (ErP).
