Built-in Motor Protector
Every FO-T/STO-T Series equipps with a self-reset circle thermal protector to prevent over-loading, locking of impeller, and scorch damage to the motor from phase failure.

Single-blade Semi-open Non-Clog Impeller shreds and pumps out any rags coming in between the impeller and the suction cover. Surface hardening heat treatment is done on edges.

Advanced Shredder Mechanism
The suction cover is designed to have the emission shape grooves in order to minimize cutting resistance.


EPOXY Cable Sealing Base
Waterproof cabtyre cable prevents water infiltration, cable ends sealed with epoxy resin, and lead wires are partially tripped off for perfect resin sealing. Triple protection for the motor against water penetration.

SiC Mechanical Seal
Equipped with double mechanical seals with heat-and-corrosion-resistant silicon carbide to prevent the motor from water infiltration.
