We have the technologyRobust and resilientAdvanced technology and good design underlieWatson-Marlow industrial pumps’ long life of quality service.Our admirable reliability record is maintained by features suchas brushless DC motors, a toughened LCD screen and a toughmembrane keypad. The chemical resistance of the wholerange outlasts our competition; the powder-coated casingsoutperform stainless steel when exposed to aggressive fluidssuch as ferric chloride or sodium hypochlorite.IP66 protectionAll industrial pumps meet the criteria for IP66and NEMA 4X classification: they are secureagainst high-pressure washdown. IP31 modelsare also available in the 520 and 620 series.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 to 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 yourflow will match your needs precisely. Couple thatwith tube bores from 0.8mm to 25.4mm, and youhave a range of unbeaten versatility.Easy wiringWiring-up all the cased pumps in this brochureis standard and easy. The watertight module atthe rear of the pump has four watertight glandsproviding ample access for whatever controlsystem connections you require. Inside: nosoldering, no D-connectors, no fiddling - justlarge, clearly marked screw terminals. With clearinstructions in product documentation, you willbe up and running in minutes.RS485Full industrial-standard connectivity with RS485permanent connection to control systemsincluding PC and PLC.Status outputsFour configurable 24V relay outputs. MonitorRun/Stop; Rotation direction; auto/manualoperation; general fault alarm; automaticshut-down if the guard is opened; leakdetectedshutdown.Operator safetyOperator safety comes first, with sturdy metalor impact-resistant guards and drain ports forsafe disposal of spillages. Tool-lockable orelectronic guard switches are standard on allpumps. Optional leak detection for all models.NOW SELECTYOUR TUBEControl 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.
