Product Details

A slurry pump with two-stage impellers in series. It improves head via two-stage progressive pressurization, suitable for long-distance or high-drop transportation of high-concentration, high-solid-content slurry, applied in industrial scenarios requiring large head.

Core structure includes two series-connected impellers, double volute pump body, high-strength pump shaft and mechanical seal. Two impellers are symmetrically in series to form a continuous pressurization channel; double volute balances radial force and reduces operating load; flow-passing parts are made of high-chromium alloy (Cr27) or rubber, hardness HRC58-62, suitable for slurry transportation with concentration ≤60%.

Motor drives pump shaft to rotate two-stage impellers synchronously. The first-stage impeller sucks and initially pressurizes slurry, then the second-stage impeller performs secondary pressurization. Slurry is collected via volute and transported through outlet pipeline to achieve high-head transportation. Two impellers are precisely matched to reduce energy loss.

Product Advantage

High head: 80%-120% higher than single-stage pump under same power, max head over 500m, no need for multi-stage series;
Wear-resistant: flow-passing parts adopt wear-resistant materials, service life 30%-50% longer than ordinary single-stage pump;
Efficient and stable: motor efficiency over 90%, 15%-20% more energy-saving than traditional multi-stage pumps, double volute balances radial force, vibration ≤4.5mm/s.
