Plastics News correspondent Michael Lauzon gathered the following briefs from NPE 2003, held June 23-27 in Chicago.
Maag Pump Systems unveils gear pumps
Maag Pump Systems Textron Inc. featured a range of melt-filtration systems complementing its new and existing gear pumps.
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, said Dan Guthrie, Maag director. 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 unveiled a 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, the firm said. Only minor adjustments 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.
Black Clawson adds QFP design to lines
Black Clawson Converting Machinery Inc. extended its QFP modular equipment design to cast film and coating and laminating product lines.
QFP equipment is based on modular components that reduce equipment needs, cut project costs and speed up time to production. The new designs reduce field wiring, cutting installation time and costs, according to the Fulton, N.Y., company. They allow pre-shipment drive tuning, PLC controls and network communications checkout. The designs simplify and reduce costs for land and sea shipping.
