Features:

• Sub. Sewage pump with 4 Pole motor. Large capacity, Variety of specifications. It can be used for long-term continuous duty.  
• EF4 is cast iron submersible sewage pump(with 4Pole motor).
• EFS4 is stainless steel SS316 submersible sewage pump(with 4Pole motor).The performance is the same with EF4, only material is different.The main parts are made of stainless steel 316 to reduce the abrasion from sewage and waste water.
• Non-clogging impeller, minimized abrasive wear,large impeller clearance, and maintenance free.
• Pump is equipped with motor overload protector,it will shut off automatically to prevent motor from burnout whenever its voltage drop, impeller plugged, and other unusual conditions.
• The mechanical seal part combines with superb double set mechanical seals. You can choose more wear-resistant silicon carbide (SIC) mechanical seals to cope with harsher wastewater conditions.
• Auto float switch is optional, to operate submersible pumps automatically.The Float switch needs to be connected to the control panel.

Diagram of Submersible Sewage Pump with float switch:

Dry-running or low water level running is forbidden for submersible sewage pump,It could cause damage on mechanical seal and motor coils. To avoid this situation, installer can connect float switch on control panel, to make sub.pump on & off automatically.Single phase sub. pump can be equipped with float switch directly upon request.  

A. Connect Float switch on control panel, to run the pump automatically. 

Operation Diagram of Submersible Sewage Pump with TOS Guide Rail Device:

Through simple and convenient installation, we can connect the pump onto guide rail device. Whenever the pump needs maintenance, it can be easily pulled out through guide bar to dismantle, repair or examine the pump. For Life safety purpose, The workers no longer take big risks to go down the septic tank to do maintenance or replacement. It's safer and more convenient to do maintenance for the pump.
