STO-C Type Auto-Setter Sewage Cutter Pump

DESIGNED FOR CUTTING FIBROUS FOREIGN OBJECTS TO SMALL PIECES BY TUNGSTEN CARBIDE EDGED NON-CLOG IMPELLER
Power: 3HP and 5HP
Motor: 4 Poles

MAINTENANCE SIMPLIFIED BY AUTOMATIC CONNECTING DEVICE

The automatic connecting device performs connection/ disconnection between a pump and piping only by lifting the pump down / up along guide pipes, so the maintenance and inspection work can be done without entering the septic tank.

FEATURES

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 type Sewage Cutter Pumps are equipped with a self-reset circle motor protector to avoid over-loading, locking of impeller, and scorch damage to the motor from phase failure.

Impeller Design B1

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
