G Series
Series G™ dosing pumps 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.
Series G™ is made up of three dosing pump models, covering a very wide flow range (up to 1,800 l/h) at an excellent quality-price ratio.


FEATURES & BENEFITS
- Mechanical actuated diaphragm design
- Eliminate contour plates,easy for material pass
- PVC, PVDF & 316SS liquid end material
- High viscolity,slurry application
- Self-cleaning suction/discharge check valve
