Product Usage Instructions:

Installation and Use:

The 4-BLOCK submersible pump is designed to draw water from
clean wells, even in the presence of sand (up to 200 g/m3). They
are recommended for domestic, commercial, and agricultural
applications due to their high efficiency, reliability, and ease of
installation.

These pumps are ideal for automatic water distribution alongside
pressure tanks, irrigation systems, and more.

Application Limits:

Ensure the pump is installed at an appropriate depth in the well
with a correctly sized power cable.

Performance Range:

The performance curves comply with EN ISO 9906 Grade 3B
tolerance limits.

FAQ:

Q: What type of power cable does the pump come with?

A: The pump comes with a 20-meter power cable. A 30-meter long
power cable is available upon request.

Q: What are the available voltage requirements for the

pump?

A: Different voltage requirements are available upon
request.

Q: What frequency options are available for the pump?

A: The pump is available in both 50 Hz and 60 Hz frequency
options.
