Description

65QV-ZPR rubber vertical centrifugal pump will operate, even when fully immersed in a slurry pool. Its suction port feature a filter in order to prevent large particles from entering the pump, and this pump series is suitable for the transportation of corrosive, abrasive, and high concentration slurry.

The shaft, pump casing, impeller, guard board, filter and other wet ends are coated with a corrosion-resistant rubber, ensuring the pumps are applicable for transporting rounded slurry under highly corrosive working conditions.

During operation, all parts, with the exception of the water, are fully submerged, allowing this pump to be widely used in oil and gas, pulp and paper, chemical and fertilization, power plants, coal-washing plants and other industrial fields.

Structure features

1. Cantilever design without submerged bearings or shaft seals;

2. Wet components are available in A05 high chrome alloy and elastomer (rubber);

3. The screened inlets and large impeller passages reduce the risk of blockages;

4. Available in a pre-fabricated conical sump with quick clean facilities;

5. Replaceable strainers allows for easy maintenance;

6. Simple installation and easy maintenance.

7. Anti-wear, anti-corrosion, which let the pumps service more longer;

8. No priming required;

Design features

Less wear, less corrosion

Wetted components are available in a wide range of alloys and elastomers. Zidong selects the optimum combination of materials for maximum resistance to wear in virtually any industrial application, including those demanding both abrasion and corrosion resistance, and where larger particles or high density slurries are encountered.

• Abrasion resistant Ultra chrome® A05 alloy.

• Abrasion/corrosion-resistant Hyper chrome® A49 alloy.

• Corrosion-resistant stainless steels.

• Natural and synthetic elastomer.

No submerged bearing failures

The robust cantilever shaft avoids the need for lower submerged bearings which are often the source of premature bearing failure.

• Heavy duty roller bearings, above mounting plate.

• No submerged bearings.

• Labyrinth/flinger bearing protection.

• Rigid, large diameter shaft.

No shaft sealing problems

The vertical cantilever design requires no shaft seal.

No priming required.

The top and bottom inlet design is ideally suited for “snore” conditions.

Less risk of blocking

The screened inlets and large impeller passages reduce the risk of blockages.

Zero ancillary water costs

The vertical cantilever design with no gland or submerged bearings avoids the need for expensive gland or bearing flushing water
