EXAMPLES OF INSTALLATION

COOLING JACKET

When the pump is installed in reservoirs, rivers, or lakes, it requires an external cooling jacket (flow generator) to ensure sufficient water flow across the motor surface, preventing overheating.
Recommended for power ratings from 3 kW to 7.5 kW

The 4SR pumps are suitable for wells with a minimum diameter of 4″ (100 mm).

The submersible pump must be lowered into the well through the delivery pipe to a depth that ensures it remains fully submerged, maintaining at least 50 cm or one meter from the bottom of the well, even if liquid levels decrease during operation.

It is advisable to secure the submersible pump using a stainless-steel cable connected to appropriate attachments on the delivery port.
