New IP66-Rated Pumps from Watson-Marlow Bredel

Supplier News

Watson-Marlow Bredel  has launched three new IP66-rated pumps to meet the requirements of tough water applications.  

Backed by several years of design work and customer research, the new 520 series of peristaltic pumps offers superior levels of accuracy, reliability and control for harsh operating environments.  

The 520 series peristaltic pumps incorporate high-powered, brushless DC motors and die cast polyester-coated cases to offer excellent performance in applications that require maximum durability and safety.  

Generating a flow rate of between 4 microlitres and 3.5 litres per minute, the new 520 peristaltic pumps have a set speed accuracy of 0.1% and can be calibrated by weight or volume for accurate metering.  

Key features of 520 series peristaltic pumps: 

  • Logical programming and user-friendly operation
  • Provides user feedback via the pump's own display
  • Dual analogue input to control and scale speed
  • Drop-in alternative for diaphragm or piston pumps with variable stroke control
  • Available with three drive configurations
  • Auto-restart function and a 'max' key for rapid priming and purging

The 520UN/R2 peristaltic pumps in the series facilitate remote/auto operation, incorporate pump-status outputs and can be password-protected.  

For full industrial connectivity, the 520DuN/R2 possesses both analogue and RS485-network options for control PLC.  

The 520 series IP66 pumps meet a wide range of pump management requirements demanded by the water industry, including trouble-free pumping of abrasive slurries and gaseous liquids.  

Richard Green, 520 product manager at Watson-Marlow Bredel says that the new 520 pumps feature best-in-class controls while the software is fully protected and has alarm outputs, offering engineers security and confidence in tough chemical or water treatment environments.  

The new 520 IP66-rated pumps provide cost-effective metering, whilst minimising maintenance requirements and associated costs of ownership due to their non-contact, self-priming and safe dry running peristaltic pumping action.
