Watson-Marlow Bredel  is a world-leading supplier of peristaltic pumps.  

The new 520Di pumps are high accuracy benchtop dispenser pumps that offer high functional value with user-friendly features such as an on-screen menu, easy-to-use tactile membrane keypad and an alphanumeric display.  

The 520Di benchtop dispensers feature a brushless DC motor with 3,500:1 speed control. Full RS485 control is enabled via serial communications.

For microlitre flow, low volume multi-channel dispensing, the 505CA is available for up to 48 channels.
