CHICAGO (July 16, 1:50 p.m. EDT) — Maag Pump Systems Textron Inc. featured a range of melt-filtration systems complementing its new and existing gear pumps at NPE 2003.
On its smaller, manual Wil-Man screen changer, Maag introduced a torque multiplier ratchet that increases an operator's effective force by a factor of five, Dan Guthrie, Maag director, said at the show, held Jan. 23-27 in Chicagos. For medium-size extruders, Maag has a new multiple-candle filter that ensures lower pressure drop and longer periods between screen changes.
Guthrie said Maag has integrated several acquisitions in the past three years that launched it into screen changers. Acquisitions included LCI Corp. International's fluid systems, Engineered Filtration Co. Inc. and Wil-Man GmbH.
Maag introduced a new discharge gear pump to replace older versions of its Vacorex product line. Vacorex MR is a compact unit that easily retrofits previous versions and increases capacity by more than 30 percent. Only minor adjustments such as positioning of the drive unit or heating connections are needed. Guthrie said while economic conditions are weak, extruders have an opportunity to retrofit and increase capacity for future growth.
Maag used its 20 years of thermoplastics compounding experience to develop the new Rubbex elastomer pump. It combines a gear pump, feed unit, filter and a universal die. Available in four sizes up to 2,200 pounds per hour, it can combine straining and forming processes in a single step to allow production of semi-finished goods.
