ZJQ Submersible Slurry Pump

Product Overview

ZJQ submersible slurry pump is a vertical single‑stage centrifugal pump. The motor and pump are integrated into one unit, working fully submerged in medium. No pump house is required and suction‑lift limitation is eliminated. Equipped with agitator impeller at the bottom, it stirs deposited sediment and slag into turbulent flow for high‑concentration slurry pumping. It is special wear‑resistant equipment for mining and dredging, an ideal replacement for traditional vertical sump pumps and horizontal slurry pumps under harsh abrasive conditions.

Structural Features

Integrated submersible design: Compact motor‑pump assembly works under water. No vacuum priming needed. Easy installation and relocation, low noise and small footprint.

Bottom agitator impeller: Stir settled sludge and sediment to avoid deposition, realize high‑concentration pumping without extra mixing equipment.

High‑chromium wetted parts: Impeller, casing, liner and agitator wheel adopt high‑chromium alloy by resin‑sand precision casting, excellent anti‑abrasion performance and long service life.

Dual reliable mechanical seal: Pressure‑balanced oil‑chamber structure prevents slurry and impurities from entering motor cavity to avoid leakage for long‑term underwater operation.

Wide‑flow‑passage impeller: Large passage for solid particles, good anti‑clogging performance for sand and tailings slurry.

Optional motor protection: Over‑temperature and water‑intrusion protection available to prevent motor burnout.

Application

Tailings transportation in mining & metallurgy, coal‑slurry pumping in coal‑washing plant, river/reservoir dredging, sediment tank desilting, power‑plant ash handling, sewage sludge transfer, sand extraction and tailing pond slag removal.

Medium

For abrasive slurry mixed with sand, ore slag, coal slime, tailings and silt. Medium temperature ≤60℃. Maximum solid weight concentration up to 30%. Custom submersion depth available. Not for flammable‑explosive media.
