Submersible electric pumps: models and uses

From the emptying of a cellar flooded at the management of wastewater in a construction site, the submersible electric pumps represent an indispensable solution for the movement of liquids. GMP Pumps offers a wide range of machines designed to combine mechanical reliability and ease of maintenance.

Solutions for the Home: Colibrì Series

For those looking for a compact yet extremely durable solution for the home, the Colibrì Series (available in the versions Standard and Vortex versions) is the benchmark in terms of quality.

These pumps are equipped with single-phase motors (0.44 – 0.6 kW) cooled in an oil bath, a feature that extends their operating life. But the real strength of strength of the Colibrì series is the innovative management of the electrical part:

The advantage in practice: It is possible to work on the capacitor or the a9> part electrical without dismantling the casing of the motor. Simply remove the connector on the side, making maintenance quick and clean.

Professional Performance: Condor and Kormoran

Moving up in size, we find the professional series (80, 120, 180 and 200), which are distinguished by the type of cast iron impeller used:

• Series KORMORAN (Vortex Impeller): The impeller is “set back” relative to the mouth of the suction inlet. This creates a vortex that allows the residues of pass freely without clogging the pump. It is the ideal choice for water loaded with debris.

• Series CONDOR (Single-channel impeller): Designed for when it is necessary to overcome significant level differences. The impeller is engaged directly on the levelling surface, ensuring a higher head to push the water towards distant drains.

Technology and Robustness: Designed for Emergencies

All the electric pumps submersible professional by GMP Pumps share construction features of high quality:

• Engine in oil bath: allows the operation for short periods even if the pump is not completely immersed.

• High-quality mechanical seals: single for double seal for models 80-120 and single for 180-200, always protected in an oil chamber.

• Solid passage: capacity to handle solid objects up to 40-45 mm.

Thanks to these specifications, in addition to civil use, these pumps are the preferred choice in the construction industry for emptying excavations and by the Civil Protection Agency for emergency interventions in the event of flooding, where speed of intervention and water flow rate (up to 2.2 kW of power) make all the difference.
