VIKING Motor speed – Internal gear pumps


The VIKING internal gear pump of the Motor Speed Series has been designed to allow the direct coupling of the pump to the 4/6 poles electric motors. The reliability of performance at high speeds is made possible by a shaft bearing system with two ball bearings. The low installation costs are guaranteed by the absence of helical gearboxes. The available materials are cast iron, carbon steel and stainless steel. It is possible to arrange the jacket on the head to control the temperature of the pumped product, the by-pass valve.
