STO-T series Auto-Setter Non-Clog Sewage Pump

Power: 1 - 10 HP
Motor: 2 Poles

DESIGNED FOR SEWAGE APPLICATION AND MAINTENANCE SIMPLIFIED BY AUTOMATIC CONNECTING DEVICE.

Categories: , ,

Thw STO-T pump has equipped with single blade semi-open non-clogging impeller with advanced shredder mechanism which is designed to destroy the sewage solid by tearing, breaking and ripping them to pieces.

FEATURES

a self-reset circle motor protector to avoid over-loading, locking of impeller, and scorch damage to the motor from phase failure.

Built-in Motor Protector

Every FO-T/STO-T type are equipped 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 Non-Clog Impeller

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.

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.

Advanced Shredder Mechanism

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

cable ends sealed with epoxy resin, and lead wires are partially tripped off for perfect resin sealing.

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.

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

SiC Mechanical Seal

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

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.
