Mining Submersible Slurry Pump with Agitator (BQZ)

Industrial valves and fittings dispatch fast — wear parts and complete machines quoted on request.

Slurry & Gravel Pumps

Centrifugal slurry and gravel pumps for mill discharge, tailings, ash and coarse solids — metal-lined or rubber-lined, with the head range matched to tailings lift, cyclone feed and transfer duty. Images are representative renderings of each series; finish, accessories and nameplate follow the confirmed drawing.

Submersible slurry pump built for sumps and dredging where a vertical shaft pump runs out of shaft length: the whole unit goes into the slurry, up to 20 m submergence, with an agitator under the suction that keeps settled solids in suspension. 81 models cover 20 to 1,200 m³/h at 10 to 90 m head on 5.5 to 200 kW, discharge DN50 to DN300, cast in high-chromium Cr26 for the agitator and impeller and QT600-3 for the casings. Rated for slurry up to 1.3 kg/L, 60 % solids by weight, pH 4 to 10 and 40 °C. Two things to settle before quoting: the BQZ series is the mining flame-proof version, so the electrical certification costs money a Middle East customer does not need — ask for the non-flameproof build — and the nameplate voltage is 380 / 660 / 1140 V, so the motor must be confirmed for 380–415 V at 50 Hz or 440 V at 60 Hz before the order is placed.
