6SR 6″ submersible pumps

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.

※ The 6SR pumps are suitable for wells with a minimum diameter of 6″ (153 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 metre 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 toappropriate attachments on the delivery port.
