EPOXY Cable Sealing Base
Waterproof cabtyre cable prevent 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.
Built-in Motor Protector
Every STO-C Series Sewage Cutter Pump is equipped with a self-reset circle motor protector to avoid over-loading, locking of impeller, and scorch damage to the motor from phase failure.
Powerful Cutter Impeller
Single-blade semi-open non-clog type impeller with a sintered tungsten carbide alloy tip
Cutter Impeller and Special Suction Cover
A sintered tungsten carbide alloy tip is brazed onto the impeller vane and the suction cover is designed to have the emission shape grooves in order to minimize cutting resistance. This "cutting mechanism" ensures materials are held for complete shredding in order to prevent clogging in the pump, discharge pipes and valves
