The world's first PROFIBUS-enabled IP66 peristaltic pumps
Product News Thursday, January 13, 2011: Watson-Marlow Bredel SA
Watson-Marlow Pumps has launched three new IP66 rated cased peristaltic pumps with certified PROFIBUS DP networking capabilities, namely the 520Bp, 620Bp and 720Bp.
- 520Bp - Flowrates up to 3.5 litre/min, pressures up to 7 bar
- 620Bp - Flowrates up to 18 litre/min, pressures up to 4 bar
- 720Bp - Flowrates up to 66 litre/min, pressures up to 2 bar
In the past it has been necessary to use a PROFIBUS gateway to control cased peristaltic pumps using this protocol, but never before has diagnostic data been available remotely via PROFIBUS. Compared with non-networked pumps, the PROFIBUS-compatible units reduce engineering, hardware and installation costs, as well as offering 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. In the unlikely event of a failure, the pump will transmit an initial alarm notification covering the following: 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 following diagnostic errors: Overcurrent, Over/Under voltage, Over temperature, Motor stalled and Tacho fault.
Pumps feature LoadSure elements which allow one-minute maintenance and guaranteed element loading improves accuracy and tube life. Patented 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 PROFIBUS-enabled pumps include maintenance-free brushless DC motors that consume 30 per cent less energy and ingress protection to IP66.
