500series

520Di/L IP31 and 520DiN/L IP66
high accuracy dispensers

Flexicon Liquid Filling

FEATURES• Dispensing accuracy to ±0.5%• Single or twin channel flows• Flow rates up to 4400 ml/min (69.74 USGPH)• Full calibration by weight or by volume with choice of units• “Suck-back” facility eliminates drips at dose end, plus ramps
ensure soft start and end of dose
• Up to 50 dispensing programs including dose parameters andcalibration can be stored in the memory with full file name• 505L pumphead features low inertia stainless steel rollers andtwin offset track to provide smoothed flows.
• One 505LX extension pumphead can be used to double the flow
