Grundfos DDE Pumps

Dosing Installations Based On Grundfos PumpsGrundfos DDC Pumps

Description

As an official Grundfos distributor, we offer a wide range of membrane-based dosing pumps with a stepper motor.

These pumps are characterized by their high endurance, thanks to the implementation of teflon membranes. They possess an universal an universal mounting plate, thanks to which the pump can easily be mounted in any place (including on walls or storage tanks).
The typeseries features a full jump duration, to provide optimal accuracy of submerging and suction even in cases of fluids with high viscousity or ones with a degassing effect. The duration of each jump varies in accordance with the set efficiency, which provides an easy and steady flow.
The latch based mounting plate allows the pump to be mounted in three different positions. The control cube can be placed in front, on the right or on the left side. The dosage efficiency can be selected through a logaritmic scale knob, in the range of
0.1-100%.

Purchase and installation

Installation:
Environment temperature range: 0 .. 45 °C
Suction stub pipe: 4/6, 6/9, 6/12, 9/12 mm
Piston stub pipe: 4/6, 6/9, 6/12, 9/12 mm

DDE 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.

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.
