YOUR CHOICE OFDRIVESWe have the technologyClean and reliableAdvanced technology and design underlie Watson-Marlowhygienic pumps’ long life of quality service.Our reliability record is maintained by features such asbrushless DC drive, a toughened LCD screen and a ruggedmembrane keypad. The chemical resistance of the wholerange outlasts our competition; using a powder-coated IP66casing that outperforms stainless steel when exposed toaggressive fluids and cleaning agents.PIN-secure processprotectionCustomize your pump setup to your precise validatedprocess needs and lock it. With twin Pin-secureProcess Protection, top-level PIN-code holders retainfull control. Calibration can also be released toproduction staff with second-level PIN access.Profibus casedpumpsNo point-to-point wiring and a simple 9-pinPROFIBUS connector means real-time, two waycommunication for pump control and statusfeedback, including a full range of diagnosticinformation. The 520, 620 and 720 series pumpsrun from the same GSD file which enables trueprocess scaling. Pumps communicate at the fullPROFIBUS bus speed range, automaticallydetecting and adjusting to fit your network.Speed scalingProgrammable twin analogue inputs allow flowpacing to be coupled with downstream qualityfeedback. The second input over-rides the mainspeed control, making stroke adjustment on adiaphragm pump redundant. Drop-in diaphragmpump replacement could not be simpler.AccuracyClass-leading flow control up to 3,600:1 andsimple, accurate configuration mean that your flowwill match your needs precisely. Couple that withtube bores from 0.5mm to 25.4mm and you havea range of unbeaten versatility.Operator safetyOperator safety comes first, with sturdy metalor impact-resistant guards and drain ports forsafe disposal of spillages. Tool lockable or electronicguard switches are standard on all pumps. Optional leakdetection is available for all models.IP66 protectionAll hygienic pumps meet the criteria for IP66and IP66 classification: they are secure against highpressurewashdown. IP31 wipe-down modelsare also available in the 520 and 620 series.Status outputsFour configurable relay outputs. Monitor Run/Stop;Rotation direction; Auto/Manual operation; general faultalarm; automatic shut-down if the guard is opened;leak-detected shutdown.RS485Full industrial-standard connectivitywith RS485 and easy-wire relays for permanentconnection to control systems including PCand PLC.Control rangeVoltage/frequencyMaximum voltagefluctuation520: 0.1-220 rpm; 620: 0.1-265 rpm; 720:0.1-360rpmFiltered 100-120V/200-240V 50/60Hz 1ph±10% of nominal voltage.
