Metering pump / close-coupled - max. 4.6 l/min | 521 series
Watson Marlow close-coupled industrial pumps are equipped with LoadSure low-pressure element pumpheads. 521 close coupled pumps are suitable for light industrial applications. They have IP55 ingress protection. They provide robust, industrial pumping and include all pumphead features of cased drives at minimal lifecycle costs. The 520REL low-pressure LoadSure element pumphead provides greater large swept volume along with sprung rollers for improved accuracy. The track and rotor are of polyphenylene sulphide, which displays high chemical resistance. Rollers and bearings are made of stainless steel. It offers low rotational speeds, which significantly improve tube life and system dependability. Fast and simple tube loading is provided by the clutched rotor. It has a very strong guard, which is tool-unlockable.
521VI Varmeca close coupled drives provide 10:1 speed control, consistent torque and complete dependability to the industrial environment. Power options include 230V and 400V three-phase plus 110V and 230V single-phase. It can be controlled by a big speed knob and forward/reverse switching.
Varmeca integral inverter provides 10:1 control ratio with highest speeds of 63 rpm, 220 rpm and 275 rpm. It provides stop/forward/reverse control and digital or analog remote control. It also provides a PROFIBUS option.
