Milton Roy – GM series


The dosing pumps of the G™ Series are electric motor-driven pumps with mechanical diaphragm liquid ends. Simple, economical and rugged, they offer great flexibility and a wide selection of liquid ends compatible with most chemicals. With a corrosion-resistant plastic or aluminium housing, depending on the model, they are based on two technologies previously only used for intensive-use industrial pumps: variable eccentric drive and stroke adjustment.
The G series is made up of three dosing pump models, covering a very wide flow range (up to 1,200 l/h) at an excellent quality-price ratio.

GM: Most robust configuration

The GM series has the most robust and versatile configuration in the G series.
