Submersible pump with bottom suction ESPA ACUARIA 27 4M A
The ACUARIA 27 4M A model retains all the advantages of the 27 4M series while additionally being equipped with a float switch that automatically monitors the water level in the source. Thanks to the float, the pump safely shuts off when the water level drops and restarts when it recovers — completely preventing dry running, extending service life, and enabling fully autonomous operation.
The bottom water intake allows efficient operation even at minimal water levels, while the coarse filter protects the impellers and hydraulic section from abrasive particles. The high-precision hydraulic assembly made of stainless steel and polymers ensures stable pressure and high performance.
Applications of ACUARIA 27 4M A:
▪️ deep wells and sources with unstable water levels;
▪️ reservoirs requiring automatic start/stop;
▪️ continuous domestic water supply;
▪️ automatic irrigation systems;
▪️ rural or district water supply networks;
▪️ agricultural and farm installations with seasonal water levels.
Advantages of the A version:
▪️ automatic protection against dry running;
▪️ no need for manual water-level supervision;
▪️ fully autonomous operation;
▪️ safe start and stop of the pump;
▪️ maximum reliability under fluctuating aquifer conditions.
