Electric Submersible Sewage Sludge pump

What's special about these electric submersible sewage sludge pump:

They're designed to handle the nasty stuff that clogs normal pumps - think toilet paper, rags, even rocks can go through without jamming.

They save energy while doing this tough job.

They install and run automatically - just drop them in and they do their thing.

Why they don't clog:

The spinning part inside (impeller) is shaped like a smooth, twisted tunnel (single or double tunnel design) instead of having normal fan blades. Stuff just slides right through.

It's like flushing a toilet - everything keeps moving along without getting stuck.

Extra smart features:

The pump case is shaped perfectly to keep water flowing smoothly (that's the "volute chamber" they mention).

The spinning parts are perfectly balanced (like a car tire after balancing) so it runs super smooth without shaking.

The seals are heavy-duty to prevent leaks, even with all the junk going through.

Basically, these are the "garbage disposals" of pumps - they eat whatever you throw at them without choking, use less electricity than old-style pumps, and work on autopilot.

 

Its extra-wide design can swallow fibers 5 times thicker than the pump itself and solid chunks half its size-no clogs, no fuss.

Seals like a fortress: The double-locked, tungsten carbide seals are corrosion-proof and last 8,000+ hours (that's nearly a year of non-stop work!).

Simple, smart, and saves money:

Compact & portable: Light enough to move easily, installs in minutes-no special pump room needed. Just drop it in and go.

Self-protecting: If water leaks into the oil, the sensor shuts things down before damage happens.

Runs on autopilot: The float switch starts/stops the pump automatically as water levels change-no babysitting required.

Stays cool under pressure: Optional water-cooling jacket (like a car's radiator) keeps it safe even in shallow or dirty water.

Bottom line: A clog-proof, low-maintenance workhorse that cuts costs and keeps running underwater.

This type of sewage pump consists of two main parts: the motor and the pump. The main components function as follows:

Signal Line 1: Equipped with a fully protected water pump control cabinet that provides comprehensive protection for the pump.

Motor Stator 8: Uses B-grade or F-grade insulation.

Leakage Probe 11: Sends a signal to the control system to protect the pump.

Mechanical Seal 13: Made of a new type of hard, corrosion-resistant tungsten carbide material, providing reliable sealing, wear resistance, and a long service life.

Impeller 17: Features a single or double channel structure, offering strong capacity for passing solids.

Pump Body 15: Paired with the impeller to achieve high efficiency.

Sealing Ring 18: Can be replaced when the impeller wears down the mouth ring, ensuring that the pump operates at optimal efficiency.

2. Electrical safety check:Test the motor's insulation – Use a meter to confirm it reads at least 2 megohms (if lower, the motor's damp and unsafe).

If insulation is weak: Bake the motor windings to dry them out, but keep it under 120°C (248°F) – any hotter could fry it!

 

3.The rotation direction of the pump after connection is counterclockwise when viewed from the inlet.

4.Unless otherwise specified, a fully automatic water pump control cabinet must be equipped.

5.The electric pump should be controlled within the recommended head range to prevent the motor from being burned out due to overload.

6.Pumps without self circulating cooling devices are strictly prohibited from being exposed to the water surface for long-term operation.
