STO series Auto-Setter Sewage Pump

DESIGNED FOR SEWAGE APPLICATION AND MAINTENANCE SIMPLIFIED BY AUTOMATIC CONNECTING DEVICE
Power: 1 - 20 HP
Motor: 4 Poles

Submersible raw sewage pump series STO offers reliable and economical pumping of heavily polluted sewage in commercial, industrial and municipal applications. The STO series pump provides excellent wastewater solid handling, and power up to 15 kW (20 hp).

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.

IMPELLER DESIGN

Design A

Dual-blade semi-open type non-clog impeller.

Design B

Single-blade semi-open type non-clog impeller.

Design C

Dual-blade shrouded type non-clog impeller.

FEATURES

SiC Mechanical Seal

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

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.

Built-in Motor Protector

All FO/STO Series Submersibe Raw Sewage 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.
