Who is it for
-
Multi-family buildings and larger water supply systems – the series’ wide range of power and flow rates makes it possible to select a model suited to the scale of water demand.
-
Farms with high water demand – higher-powered models supply extensive irrigation systems, sprinklers, and drip lines.
-
Industrial plants and fire protection systems – the all-stainless-steel construction and wide power range are suitable for demanding continuous-operation installations.
-
Installers and system designers – the option to select the cable in 5 m increments and choose the appropriate motor diameter makes it easier to adapt the pump to a specific borehole.
Applications
The 6" AP6 B21 pump is designed to draw water from deep sources for single-
and multi-family homes, farms, irrigation systems, fire protection systems,
industrial facilities and drainage systems.
The pump can operate vertically or horizontally, in wells with a minimum diameter of
with an internal diameter of 180 mm, at a maximum pumped water temperature of 35°C. The submersible pump
The 6" AP6 B21 400 V is compatible with standard pressure tanks and pressure control systems
selected to match the scale of the installation.
Features of the 6" AP6 B21 pump
The 6" AP6 pump is made entirely of stainless steel, with increased resistance to sand
and a built-in check valve limiting the return flow of water from the system after shutdown
pumps. Lower-power motors have a diameter of 4", while higher-power models use
6" motors.
The thermal protection built into the motor winding protects the drive against overload,
and the power cable can be selected in 5 m increments, adjusting its length to
well depth.
