Submersible pump with bottom suction ESPA ACUARIA 17 7M A
The submersible pump ESPA ACUARIA 17 7M A is the most productive and technologically advanced model in the ACUARIA 17 range. It combines a powerful seven-stage hydraulic system that delivers maximum head with an automatic water-level control feature — the integrated float switch.
The float switch automatically stops the pump when the water level drops, fully preventing dry running. This makes the model ideal for deep wells with unstable aquifers, seasonal sources, tanks with variable water levels and autonomous water-supply systems.
Thanks to the bottom intake, the pump operates efficiently even at minimal water levels, while the built-in coarse filter prevents sand and large particles from entering the hydraulic section. The double mechanical seal in an oil-filled chamber ensures maximum tightness and high resistance to pressure loads, which is crucial for deep-well operation and high-pressure systems.
Applications of ACUARIA 17 7M A:
▪️ autonomous water-supply systems;
▪️ deep wells starting from 6″;
▪️ farms and agricultural facilities with high consumption;
▪️ large-area automatic irrigation systems;
▪️ water supply for multi-storey buildings;
▪️ primary and backup pumping stations;
▪️ swimming pools, reservoirs and storage tanks.
Advantages of the A version:
▪️ automatic shut-off at low water level;
▪️ full protection against dry running and overheating;
▪️ operation without constant user supervision;
▪️ maximum head and high performance;
▪️ long service life and operational reliability;
▪️ water cooling for operation at any immersion depth.
