6" AP6 B21 – 400 V multistage submersible pump
The IBO ITALY 6" AP6 B21 submersible pump features a multistage construction made entirely of stainless
steel. It is designed
for large water supply, industrial, fire protection, and irrigation systems.
The ability to operate horizontally and the built-in check valve increase
the system’s flexibility and reliability.
Who it’s for
-
Multi-family buildings and larger water supply systems – The series’ wide range of power ratings and flow rates makes it possible to select a model suited to water demand.
-
Farms with high water demand – Higher-capacity models supply extensive irrigation systems, sprinklers, and drip lines.
-
Industrial plants and fire protection systems – The all-stainless-steel construction and wide power range make these pumps suitable for demanding, continuous-duty installations.
-
Installers and system designers – The ability to select a cable in 5 m increments and choose the appropriate motor diameter makes it easier to match 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,
industry, and drainage.
The pump operates in a vertical or horizontal position in wells with a minimum internal diameter of
180 mm, at a maximum pumped water temperature of 35°C. The 6" AP6 B21 400 V submersible pump
works with standard pressure tanks and pressure controls selected to suit the scale of the system.
Features of the 6" AP6 B21 pump
The 6" AP6 pump is made entirely of stainless steel, with increased sand resistance
and a built-in check valve that limits water from flowing back from the system after the pump is switched off.
Lower-power models have a 4" diameter, while 6" motors are used at higher power ratings.
Thermal protection built into the motor winding protects the drive from overload,
and the power cable can be selected in 5 m increments to match its length to the
well depth.
