STO-C series Auto-Setter Sewage Cutter Pump

Power: 3HP and 5HP
Motor: 4 Poles

Designed For Cutting Fibrous Foreign Objects To Small Pieces By Tungsten Carbide Edged Non-Clog Impeller

Categories: , ,

The single-blade semi-open type non-clog impeller with a sintered tungsten alloy tip runs against a special grinding suction cover, shredding and cutting fibrous foreign objects into small pieces to pump through the body to waste.

FEATURES

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.

Powerful Cutter Impeller

Single-blade semi-open non-clog type impeller with a sintered tungsten carbide alloy tip

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.

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

MAINTENANCE SIMPLIFIED BY Auto-Guide Rail KiT

The automatic guide rail kit 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.
