Dosing Installations Based On Grundfos Pumps

Compact, membrane-based dosing pumps, with a stepper motor that allows for speed regulation. The membrane is powered directly through electromagnetic force.

Category: Dosage pumps and systems

Description

As an official Grundfos distributor, we offer compact, membrane-based dosing pumps from the DDE, DDC and DDA series. The length of each piston ump varies depending on the set efficiency, resulting in an easy and steady flow. The pumps are suitable for, e.g.

DDE, DDC and DDA series pumps may be purchased alongside an installation set, consisting of: 2 dosing head connectors, a foot valve, dosing armature, PE dosing duct– 6 m , PVC suction duct– 2 m, PVC deairing duct- 2m. The materials and sizes are selected to fit the material construction of the pump.

Parameters- DDA Series

DDA pump parameters:
• maximum capacity: 7,5 l/h with the maximum pressure of 16 bar
• maximum capacity: 12,0 l/h with the maximum pressure of 10 bar
• maximum capacity: 17,0 l/h with the maximum pressure of 7 bar
• maximum capacity: 30,0 l/h with the maximum pressure of 4 bar

Modes of operation:
• Manual in ml/h, I/h or gph.
• Impulse in ml/impulse (with a memory function).
• Analog 0/4-20 mA (scalable).
• Impulse based dose control, in ml, l lub gal.
• Timer based dose control (Transmitter time-based, cyclic or weekly).
• Fieldbus DP control (Genibus suited for Profibus E-box).

Head material:
• PP
• PVC
• PVDF
• Stainless steel

Waterproofing (availability depends on selected head):
• EPDM
• FKM
• PTFE

The dosing sets can additionally be equipped with:
• multipurpose valves – installed directly on the piston side of the pump. Upper connection to the piston duct, side connection returns excess fluid back to the tank. These valves allow for deairing the pump and emptying the piston duct.
• suction lances- with or without a level sensor,
• hand mixing tool, beater type,
• water meter with encoder,
• PE tank with capacity: 60l, 100l, 200l,
• cart for transportation.

Parameters- DDC series

DDC pump parameters:
• maximum capacity: 6,0 l/h with the maximum pressure of 10 bar
• maximum capacity: 9,0 l/h with the maximum pressure of 7 bar
• maximum capacity: 15,0 l/h with the maximum pressure of 4 bar

Modes of operation:
• Manual in ml/h, I/h or gph.
• Impulse in ml/impulse (with a memory function).
• Analog 0/4-20 mA (only AR version).

Head material:
• PP
• PVC
