Dosage module Dosage Module


Dispensing unit for precise low volume dosage The dosage module for the mzr-2505 (S/F), mzr-2905 (S/F) and mzr-4605 (S/F) pumps can be used for volumetric dosage of adhesives like UV cure adhesive, epoxy resin, screw fixing varnish, lubricants and silicon. The dosage module suits the dispensing of smallest amounts of liquids requiring highly precise handling (small beads or spots) and the absence of afterrun. The liquid can be supplied from a 30 or 55 ml disposable cartridge which is directly connected to the pump. For liquids with higher viscosity, pressure of up to 5 bar may be applied to the cartridge. An air discharge screw enables to bleed the system after cartridge exchange or to supply flushing liquid for cleaning. The dosing needles can be directly connected to the Luer-Lock male adapter of the pump. With the fixing bracket the module may be mounted onto the handling device.
