Single support cart for gear pump and screen changer

A concept that combines screen changer and gear pump on a single movable cart simplifies deployment of these components in an extrusion line, takes up less floor space than separately mounted machines, and provides easy access for replacement of filter media, it was announced by Nordson Kreyenborg GmbH.

The single cart is mounted on fixed casters that permit transverse-direction movement into and out of the extrusion line, while precisely aligned movement in the extrusion direction is provided by rails installed on the floor. At the same time, linear guides on the cart permit independent extrusion-direction movement of the gear pump and screen changer. To save space and facilitate access for changing screens, the company has in effect turned the gear pump onto its side so that its drive can be mounted below the pump.  The gear pump in this system incorporates the same features as the traditionally configured equipment, including a cooling system that enhances the effectiveness of the thread shaft seal, which is particularly important for low-viscosity materials. The rate of coolant flow is adjustable, and the coolant may be either air or de-mineralized water.

Maag Pump Systems: Gear pump technology

With the launch of Maag Pump Systems 6th generation gear pumps, first unveiled at the show, Maag has redesigned every single component featured in its pump portfolio, from gears and shafts through to bearings and seals, fine-tuning how all components interact. According to Maag, customers will mostly benefit in terms of productivity and process security in a variety of ways.

The portfolio is comprised of multiple sizes covering throughput ranges from a few kg/h up to 100t/h, with application-optimised design options. Sizes 250 and above will be available at launch, while others will be introduced in the course of 2014.
