Watson-Marlow 520 Series IP31 Cased Clean-Process and Laboratory Pumps | Watson-Marlow Process Pumps


520 Series IP31 Cased Clean-Process and Laboratory Pumps

A new generation of mid-flow peristaltic pumps specifically designed to meet the needs of industrial and process pumping by delivering unrivalled performance, accuracy and reliability. All have membrane keypads, microprocessor control and bright digital displays.

The 520 series feature the 520R and 520R2 pumpheads with their large swept volume and low rotational speeds, for high accuracy and long tube life. The 520S, 520U and 520Du pumps can be fitted with four alternative pumpheads for high accuracy dosing, multi-channel flows or very low flow pumping up to 48 channels.

  • The 520S/R and 520S/R2 has manual control and a maximum flow rate of 55.5 gph (3.5 litre/min).

  • The 520U/R and 520U/R2 accepts analog auto and manual control.

  • The 520Du/R2 accepts RS232, analog auto and manual control.

For overview please refer to 520 Cased Pumps brochure.

520S/R2 manual control pumps

  • Flow rates from 4 microlitres/min up to nearly 1 gpm.

  • Brushless motor, 2200:1 turndown, 0.1% set speed accuracy.

  • Large speed/flow display and easy to use tactile membrane keypad. Incorporates keypad lock.

  • Manual control and flow rate calibration.

  • MemoDose for accurate single shot dispensing.
