This is a Submersible Sewage / Dirty Water Pump
What it’s used for:
Pumping water that has solids, sludge, or debris in it. You drop it straight into the water/tank/pit and it pumps out through the side discharge.
Key details from your pic:
1. Type: Submersible centrifugal pump
• Stainless steel body + Cast iron base/motor housing = corrosion and abrasion resistant
• Side discharge with a barbed hose/pipe fitting
• Long power cable + Schuko plug = for 220-240V, typical in Nigeria/Edo State
• Lifting handle on top to lower/raise it
2. Design: The bottom has a wide strainer base. That lets it pass small solids without clogging. The motor is sealed inside the stainless canister.
