Tough pumps for chemical dosing
Keywords Milton Roy, Pumping
Some applications demand robust, mechanically actuated diaphragm pumps, for example dosing chemicals in water treatment and industrial processes, and these are thought to be ideal situations for the "G" series of pumps.
Available from Milton Roy UK, these "G" series pumps (Plate 6) are claimed to incorporate important features, such as variable eccentric system for stroke length. This type of system, usually found in much larger pumps, helps to reduce the shocks created by spring return lost motion designs which are traditionally used in pumps with these output ranges.

Also, the use of ball-bearings and only two major moving components (connecting rod and wheel/eccentric assembly) ensures minimum friction and so eliminates the build-up of heat in the drive. These features combined are believed to make a significant contribution to the reliability and durability of the pump.
"G" series pumps can reportedly deliver flow rates not normally associated with mechanically actuated diaphragm pumps, for example up to 1,100 litres/hour.
Liquid end assemblies can be specified to suit a variety of chemicals across a wide range of applications, for example Polypropylene, PVDF, 316 stainless steel and versions for high viscosity, amines and fluorinated liquids. To meet other application demands accessories can be supplied to provide anti-siphon, back-pressure, relief, priming aid, gas bleed and damping functions.
