The 700 series provides the highest capacity available from Watson-Marlow's cased pump series with flow rates up to 2000 liter/hour from one 701R pumphead. Fitting a 701RX extension pumphead gives either twin channels of up to 2000 liter/hour or a combined output of up to 4000 liter/hour. Cased drive units and control circuits are housed in a tough IP55/washdown enclosure, providing manual control on the 704S/R or manual/auto-control on the 701U/R which allows a pump located in a harsh or hygienic environment to be remotely operated. Tube bores in five sizes from 9.6mm to 25.4mm in a choice of five tube materials may be fitted in the 701R pumphead, which, with its unique driven roller action ensures that the utmost tube life is attained in any application. Further options are single and three phase industrial drives mounted on baseplates with inverter and mechanical variator controls, or pneumatic drives. |
