FEX5
SUBMERSIBLE WELL PUMPS
The monobloc electric pumps of the FEX5 series are suitable for use in tanks or shallow wells with an internal diameter of at least 130 mm. The main feature is that the hydraulic section is positioned below the motor, allowing a lower suction level and ensuring proper motor cooling even when installed in a tank.
The hydraulic design is traditional, with technopolymer impellers fixed on the shaft. The motor is asynchronous and cooled by the pumped liquid. As standard, a double mechanical seal with an intermediate oil chamber is installed to guarantee excellent performance and long service life under demanding conditions.
All structural components are made of AISI 304 stainless steel; there are no cast iron or other materials subject to degradation over time.
The power cable and float switch are connected to the pump via removable connectors, allowing stock reduction. Power cables of 10–20–40 m in H07RN-F are available.
The standard single-phase version is equipped with an internal capacitor with automatic reset overload protection and cable with Schuko plug. Upon request, it can be supplied without capacitor, with a three-wire cable and external control box.
