Submersible Slurry Pump — Heavy-Duty Dewatering & Solids Handling
A submersible slurry pump (SZBQ) is an IP68 motor-and-pump unit that runs submerged in abrasive slurry for mine and site dewatering and solids handling.

The SZBQ range is a fully submerged pump-and-motor unit for abrasive solids in mining, metallurgy, power generation, coal handling, river and lake dredging and sand extraction. Because the unit sits directly in the sump, no pump house, foundation or suction pipework is required, which removes the civil works normally needed for a dry-installed set. Typical media are coal slime, iron oxide, mineral concentrate, ash, silt and gravel at up to 70 degrees C.
Duty Envelope and Wet-End Materials
Flow reaches 10-6,000 m3/h against 8-60 m of head, with motors from 3 to 450 kW, bore 80-500 mm and impeller diameters of 150-600 mm. Solids are accepted to 50 mm particle size and 60% by weight (45% for mortar), specific gravity to 1.3, immersion to 20 m, at pH 6-8 on the standard build and pH 4-10 on the industrial build. Wet parts are cast in 27% chrome A05 alloy for abrasion and mild corrosion.
Sealing and Motor Protection
Two tungsten-carbide mechanical seals run in series with an oil chamber between them: the outer seal faces the slurry, the inner seal keeps oil out of the motor, and the chamber acts as a buffer if the outer seal is breached. Seal service life reaches 30,000 hours. The motor is IP68 with class F insulation, a 4-pole IE3 stator on 600-grade silicon steel, a Q235 shell with 316 fasteners and a tempered 4Cr13 shaft. An oil-water probe, float switch and winding thermistor feed a PLC display that alarms and stops the set on leakage, overload, phase loss, short circuit or bearing over-temperature.
Installation and Service Intervals
Two mounting arrangements are offered. The fixed arrangement uses a guide-rail bracket bolted to the sump floor so the pump can be hoisted out on a chain and reseated on the discharge elbow without draining the sump; the mobile arrangement is simply lowered in. Mechanical seals are changed at 4,000 hours and bearings re-greased at 2,000 hours. A bottom agitator or cutter can be fitted where settled sludge needs to be fluidised before it will pump.

Submersible Slurry Pump for Mining DewateringSubmersible Slurry Pump with AgitatorHow do you prevent motor water ingress — double mechanical seals and an oil chamber?
Yes. The SZBQ uses two pairs of tungsten-carbide-faced mechanical seals separated by an isolating oil chamber, in an IP68 enclosure with an F-class insulated 4-pole IE3 motor and 600-grade silicon steel. Seal service life reaches 30,000 hours, with seal replacement at 4,000 hours and bearing re-greasing at 2,000 hours. Electrical protection covers overload, phase loss, short circuit, water ingress, winding over-temperature and bearing over-temperature, with oil-water probes, float switch, thermal overload and PLC display. The range covers 10–6000 m³/h at 8–60 m head, 3–450 kW, bore 80–500 mm, impeller Ø150–600 mm; medium up to 70 °C, particle to 50 mm, solids to 60%, immersion to 20 m, pH 6–8 (4–10 on the industrial build), specific gravity to 1.3.
Do you hold CE / EAC / ISO 9001, and can you export to the EU, Russia and the CIS?
Yes — ISO 9001/14001, CE (MD·EMC) and EAC 004/010. EAC certification is key for Russia and CIS customs clearance.
What after-sales and overseas spare-parts support do you provide?
Wet-end and spare parts are supplied for every series we build. The group exports to more than 100 countries and supports customers through 10 branches and more than 100 overseas offices; parts enquiries are quoted on request.
