ProMinent - Model Makro TZ - Diaphragm Metering Pump
From Process Metering Pumps - Diaphragm Metering Pumps
Capacity range of single head pump: 260 – 2,100 l/h, 12 – 4 bar - The modular construction of the diaphragm metering pump MAKRO TZMb with adjustable eccentric drive mechanism and mechanically deflected multi-layer safety diaphragm enables it to be outstandingly adapted to the performance requirements of the respective application.
Overview
Greater safety in continuous operation through mechanically deflected multi-layer safety diaphragm.
The diaphragm metering pump MAKRO TZMb has an adjustable eccentric drive mechanism and, together with the Makro TZ plunger metering pump, forms a range of drive mechanisms with stroke lengths of 10 or 20 mm. A wide range of drive versions is available for use in areas at risk from explosion with ATEX certification.
Your Benefits
Excellent process safety and reliability:
