Watson-Marlow Bredel  supplies the new 520RE 7 bar (100psi) constant pressure pumps offering flow rates up to 450ml/minute.  

The new pumps have 520RE LoadSure elements pumphead fitted as standard, featuring a large swept volume with sprung stainless steel rollers for high accuracy.

The 7 bar constant pressure pumps are suitable for applications in industries such as chemicals, wastewater/ water treatment, mineral processing, pulp and paper, food and beverage as well as printing.

Low rotational speeds greatly increase tube life and system reliability.

LoadSure elements fit into position for simple, error-free tube loading to ensure optimum performance every time.

The element can be changed in less than a minute using the patented LoadSure D-connectors and easy-grip clutched rotor. 

These pumps are available in three models:

The 520UN/REH pump accepts 0-10V, 4-20mA, 5V TTL and 24V industrial logic inputs. It provides 0-10V, 0-1258Hz analogue speed, 5V TTL and 24V logic outputs.

The 520DuN/REH model has an additional 4-20mA output.

Series 520 drives provide superior performance, long life, reliability and great value for all industrial applications.
