Product Description

The AIER® WG Series High Head Slurry Pump is a premium, high-efficiency centrifugal solution engineered specifically for the demanding requirements of the electric power, metallurgy, and coal industries. Designed for large capacity and high head delivery, these horizontal, single-stage, single-suction pumps are ideal for removing ash, sludge, and transporting liquid-solid mixtures. By integrating advanced CAD design with superior hydraulic performance, the WG series ensures maximum throughput while significantly reducing abrasion rates in the most challenging industrial environments.

Built for versatility and durability, the WG(P) series supports both single-stage and multi-stage series configurations to achieve the precise pressure needed for long-distance slurry transport. With a focus on reliability and ease of maintenance, these pumps feature specialized sealing systems—including expeller seals combined with packing or high-pressure mechanical seals—to prevent leakage of abrasive fluids. Whether handling seawater ash or corrosive chemical slurries, the WG series provides a robust, energy-efficient bridge between extraction and processing.

Key Advantages

Extreme Wear Resistance

Utilizing high-chrome alloys (up to 37% Cr), the pump withstands severe abrasion and corrosion in pH ranges from 1 to 12.

Extended MTBF

Reliability-centric design ensures a long Mean Time Between Failures, reducing unplanned downtime in critical plant operations.

Superior Hydraulics

Modern CAD-optimized hydraulic profiles minimize energy loss and prevent clogging via wide-passage design.

Anti-Leakage Design

Dual sealing options (Expeller + Mechanical) guarantee zero leakage of dense slurries, protecting the environment and equipment.

Thermal Stability

Integrated oil lubrication and water cooling systems ensure bearings operate at low temperatures even under high loads.

Modular Flexibility

Interchangeable wet parts between WG and WGP series allow for easy scalability and rapid replacement of wear parts.

Frequently Asked Questions

Q: What is the main difference between the WG and WGP pump models?

The WG model is a single-stage high head slurry pump, while the WGP model is designed for multi-stage series operation to achieve even higher pressures for long-distance transport.

Q: Which material should I choose for high-acid (low pH) slurries?

For low pH conditions, especially in FGD (Flue Gas Desulfurization) installations with pH no less than 4, we recommend the AB29 (27-29% chrome white iron) material.

Q: How does the WG pump handle seawater and salt mist?

The pump can be configured with specialized anti-corrosion materials for wet parts, preventing electrochemical corrosion from seawater, salt, and mist during ash removal.

Q: What are the sealing water pressure requirements for multi-stage pumps?

For multi-stage pumps with expeller seals, the sealing water pressure for the n-th stage should be: Lowest pressure = Hi + 0.7Hn (where n ≥ 2).

Q: Can the WG series handle high solids concentration?

Yes, the WG series is specifically engineered to handle dense slurries with a maximum solids concentration of up to 70% and particle sizes up to 90mm.

Q: What maintenance advantage do modular liners provide?

Modular liners allow maintenance teams to replace only the worn-out sections of the casing and impeller without dismantling the entire pump, drastically reducing labor costs and downtime.
