Watson-Marlow 520Bp, 620Bp and 720Bp Profibus-enabled pumps

Watson-Marlow Pumps has launched three IP66-rated peristaltic pumps with certified Profibus DP networking capabilities, the 520Bp, 620Bp and 720Bp.

The 520Bp provides flow rates up to 3.5 L/min at pressures up to 7 bar, the 620Bp up to 18 L/min at up to 4 bar, and the 720Bp up to 66 L/min at up to 2 bar.

Compared with non-networked pumps, the Profibus-compatible units reduce engineering, hardware and installation costs, and also offer remote diagnostics that help to minimise plant downtime and maintenance costs.

The 520Bp, 620Bp and 720Bp main control and running status functions cover start/stop, speed, direction of rotation; running hours, tacho count and flow calibration. Alarm notifications include general fault, leak detected, guard open (except 520Bp) and software version mismatch. The pump can then be interrogated over the Profibus network to give more detailed analysis of the failure and provide the other diagnostics, including overcurrent, over/undervoltage, overtemperature, motor stalled and tacho fault.

Pumps feature LoadSure elements which allow 1 min maintenance and guaranteed element loading improves accuracy and tube life. LoadSure tube elements incorporate either industrial standard or sanitary tri-clamp style connectors at either end of an accurate length of peristaltic tubing.

Other features of the pumps include maintenance-free brushless DC motors that consume 30% less energy and ingress protection to IP66.
