  |
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 1,200 l/h) at an excellent quality-price ratio.
These pumps are recommended for use at low discharge pressures, mainly in service applications such as water treatment and surface treatment, but also in the food processing industry, agriculture, etc.
- Versatile: dosing of all known reagents
- Continuous 24-hour operation
- Wide flow range
- Dry running without damage to the pump
- Set flow rate accurate to within ± 2% over the range from 10 to 100% to meet the exact needs of your process
- Automatic flow control
- Proportional control via automatic flow adjustment (VARIPULSE® options)
- Minimal pulsing and no water hammer (low output pulse) protects pipes
- Few moving parts for long service life and reduced heating
- Light, compact pumps for a small footprint and ease of handling
- Minimal maintenance with pumps lubricated for life
- Variable eccentric stroke adjustment mechanism
- Maximum suction lift: 4 m water
- Parts made from engineering plastic
- Positive return by mechanism
- Wide range of liquid ends: polypropylene, PVDF, stainless steel, high viscosity, fluorinated liquids, slurries, etc.
- Single-phase or three-phase motors. Three-phase only for Series G™B pumps
- 10 turn adjustment, servomotor options, stroke counter
- Single-phase or three-phase motors. Three-phase only for Series G™B pumps
- 100% bearing mounting and compensating spring for optimum output
- Weight: 7 to 40 kg
