Description
DAB grinder FX submersible pump 0.7kW three phase with a shredder designed for lifting and transferring wastewater in civil and commercial environments. Grinder FX is certified EN 12050-1.
The presence of the shredder makes the pump suitable for systems with small diameter pipes or those requiring high pressures. Shredder in AISI 630 stainless steel. Ideal pump for replacements thanks to its reduced dimensions and to both flanged and threaded delivery ports.

Construction features of the pump
Pump body and impeller in cast iron, shredder in AISI 630. Motor shaft in AISI 304 stainless steel. Double mechanical seal in SiC-SiC/SiC-C in oil chamber not in contact with the pumped liquid, independent of the direction of rotation. Delivery port both flanged and threaded.
Construction features of the motor
Single-phase asynchronous motor (MA / MNA versions) and three-phase version motor (TNA versions). The rotor is mounted on lubricated bearings. Continuous operation in S1 with the motor completely immersed. Dry running for a maximum time of 10 minutes. Over-temperature sensors in the motor windings with intervention threshold at +130°C. Quick-bonded resin-bonded cable gland, 07RN8-F power cable. Single-phase versions with starter and capacitor in a separate panel, MA versions with float for automatic operation. In the three-phase motors the over-temperature sensor connection is responsibility of the user.
