Sludge Sump Pump

Sludge sump pumps find wide application in industries such as metallurgy, electric power, chemical, mining, papermaking, and building materials.

1. The shaft features a large diameter and short cantilever design, ensuring high rigidity and making the pump suitable for high-power and severe operating conditions.

2. A hardened stainless steel shaft sleeve is clearance-fitted onto the shaft, with O-rings installed at both ends to protect the shaft from abrasion and corrosion.

3. The impeller is equipped with auxiliary blades on both the front and rear shrouds to reduce return flow and seal chamber pressure. It also utilizes a wide flow passage and concave blade design to enhance conveying capacity, abrasion resistance, and service life.

4. The sludge sump pump casing and cover are made of ductile iron and reinforced with ribs to ensure high-pressure resistance.
