Twinflow EVR
Metering pumps are integral to the reservoir resulting in efficient, accurate heating and control.
By design air inclusion possibilities are eliminated, important for vacuum applications. Featuring the Posiload™ precision metering pump capable of /- .05% accuracy.
This design eliminates the need of rear pump seals reducing maintenance ownership cost, eliminating resin and air leaks.
The electric drive motors are fitted on the reservoir lid these can be pneumatically lifted clear of reservoir giving easy access to metering piston and pump tube greatly reducing inspection and maintenance time of crucial parts, also it is an option for filling reservoir with resin. Each electrically driven piston is independently powered and linked to the machines PLC so a pair or range of metering pumps can be programmed to process a wide range of ratios by changing the speeds of travel.
Easy interface with XYZ co-ordinated tables or robots.
