Deep well electric pump with bottom suction ESPA ACUARIA 27 6M A

ESPA ACUARIA 27 6M A is an enhanced single-phase version of the ACUARIA 27 series, equipped with a float switch that provides automatic protection against dry running. This modification is ideal for water sources with fluctuating levels, reservoirs and systems that require fully autonomous operation.

The float activates the pump when the water level rises and shuts it off when it drops, preventing motor overheating and mechanical-seal damage. This makes the pump exceptionally reliable when operating in environments with unstable water levels.

The bottom intake ensures efficient operation even at minimal water levels. Water cooling guarantees stable performance even when the pump is only partially submerged (at least 50%).
The hydraulic components are made of stainless steel and durable composite materials, while the double mechanical seal ensures long-term operation without oil leakage or shaft wear.

Applications of ACUARIA 27 6M A:

▪️ reservoirs with variable water levels;
▪️ deep wells and boreholes with seasonal water fluctuations;
▪️ residential continuous water-supply systems;
▪️ automatic irrigation, drip and sprinkler systems;
▪️ farms, greenhouses and agricultural installations;
▪️ domestic pump stations with automation;
▪️ filling tanks and pools without the risk of dry running.

Advantages of the float-switch version:

▪️ automatic shut-off at low water level;
▪️ safe operation without the risk of overheating;
▪️ ideal for fully autonomous systems;
▪️ extends the service life of the motor and seals;
▪️ reduces load on the electrical network through precise start/stop cycles;
▪️ easy installation with no need for manual water-level monitoring.
