Features

Adopts Non-clog Vortex impeller equipped with powerful SUS316 agitator to create powerful stirring and pumping action for slurry and animal waste.It can minimize abrasive wear,allows large impeller clearance, and it's suitable for animal farms.
Pump is equipped with motor overload protector.The motor will shut off automatically to prevent motor from burnout easily whenever voltage drop occurs, impeller plugged, and other unusual conditions.
EFD adopts SIC dual Mechanical seal as standard, in order to overcome harsh environment or slurry wear.
It's available to equip with auto float switch on submersible pump.
Guide Rail device is available upon request. It's for safety purpose and easy dismantle.

Structure

The EFD Sub. Dredge Pump uses Non-clog Vortex Impeller with SUS316 agitator.
It comes with a mechanical seal made of wear-resistant SIC (silicon carbide) material.

Diagram of Sub. Dredge Pump with float switch

Dry-running or low water level running is forbidden for submersible dredge 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 on pump.

A. Single Phase Submersible Pump(0.5~2HP)can be equipped with float switch on pump.

The float switch control automatically starts the pump at a high water level to drain and prevent sewage overflow. It stops at a low water level to avoid running the pump without water, which could cause the motor coils to overheat and get damaged.

EVERGUSH EFD submersible dredge pump is equipped with a float switch and is installed in the sewage well or wastewater pit to automatically drainage waste water.

B. Connect Float switch on control panel, to run the pump automatically(For both 1 and 3 phase models).

You can choose a customized EVERGUSH control panel for EVERGUSH wastewater pumps. Panel is connected with some float switches to allow the pump system to automatically drain and shut down.You can choose a single pump to operate alone or two units (multiple units) to alternately operate in parallel. The outer box has a single door or double door(with window) choice, steel plate or stainless steel material, direct start or Y-delta start or Soft Starter control. EVERGUSH control panel is customized and designed to meet the on-site environment and regulatory requirements.

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. Because wastewater pits or septic tanks could contain deadly biogas(methane) and the environment is always extremely harsh.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.
