KSB KWP FGD Slurry Pumps: Engineered for Demanding Flue Gas Desulfurization Applications
The KSB KWP FGD Slurry Pump is a high-performance, non-clogging centrifugal pump specifically designed to handle abrasive, corrosive, and solids-laden slurries in flue gas desulfurization (FGD) systems. Built with robust materials and advanced engineering, this pump ensures reliable operation in extreme conditions, minimizing downtime and maintenance costs while maximizing efficiency in power generation and industrial scrubbing processes.
Key Features
Superior Abrasion & Corrosion Resistance
Materials: Critical components (impeller, casing, wear plates) are constructed from hardened alloys such as CD4MCu, 2205 duplex steel, A49 (high-chrome cast iron), or Norihard® to withstand acidic slurries, chlorides, and abrasive particles.
Reinforced Internals: Extra wear allowance on volute casings and replaceable wear plates extend service life in high-wear environments.
Optimized Impeller Design offers 4 types of impellers for selection:
F-Type Free-Flow Impeller: Vortex design handles slurries with coarse solids (e.g., gypsum, limestone) and entrained gases without clogging.
K-Type Closed Impeller: For high-efficiency slurry transfer with minimal recirculation losses.
N-Type Closed multi-vane impeller: Ideal for clear water and fluids with slight suspensions like treated sewage, screen water, pulp water, and sugar juices.
O-Type Open Impeller: Has the same applications as the “N” impeller, and can also handle fluids containing air.
Advanced Sealing Solutions
Conical Mechanical Seal Chamber: Integrated cooling and drainage prevent seal overheating and leakage, even with abrasive media.
Dual Mechanical Seals (Optional): ATEX-compliant configurations for hazardous areas or aggressive chemistries.
Standard Gland Seal: Designed with a standard construction.
High-temperature Gland Seal: When the temperature exceeds 90°C, the high - temperature type should be employed. The stuffing box of this type can be cooled to meet the requirements of high-temperature transportation duties.
Back Pull-Out Design
Rotor assembly (impeller, shaft, bearings) can be removed without disconnecting pipelines, enabling rapid maintenance and part replacement.
Heavy-Duty Construction
Bearings: Germany-standard, oil-lubricated bearings with a service life exceeding 30,000 hours, capable of supporting heavy radial/axial loads.
Shaft: Forged from C45+N steel or Noridur® 1.4593 stainless steel for torsional strength.
Technical Specifications
Capacity: Up to 15,000 m³/h
Head: Up to 140 m
Pressure Rating: PN 16 (16 bar)
Temperature Range:
* Standard: -40°C to +140°C
* Extended (C2 material): -40°C to +280°C
Discharge Sizes: DN 40 to DN 800 (flanged connections)
Drive Options: Direct coupling or belt drive (1:1 to 1:2 ratio).
Materials & Customization
Casing: A49 (Cr30) EN-GJL-250 cast iron (standard), upgradeable to GX260CrMo27-2 or GX3CrNiMoCuN24-6-2-3 for severe corrosion.
Impeller/Wear Parts:
* CD4MCu: Ideal for acidic slurries (pH 1–12).
* 2205 Duplex Steel: Resists pitting and chloride stress corrosion.
* A49 (Cr30): Superior abrasion resistance for high-solid slurries (pH4-14).
Seals: Configurable with gland packing or mechanical seals (1.4122/1.4539 stainless steel).
Applications
FGD Systems: Limestone/gypsum slurry circulation, absorber feed, and wastewater handling.
Power Plants: Ash slurry transfer, scrubber feed, and chemical dosing.
Industrial Scrubbing: Acidic/caustic slurry transport in chemical, mining, and metallurgical processes.
Benefits for FGD Operations
Reduced Downtime: Quick rotor access and interchangeable wear parts minimize maintenance pauses.
Energy Efficiency: Hydraulically optimized impellers reduce power consumption by up to 20%.
Leak-Free Reliability: Advanced sealing systems prevent environmental contamination.
Longevity: Corrosion-resistant materials and hardened internals slash lifecycle costs.
Compliance & Certifications
ATEX Directive 2014/34/EU: Explosion-proof versions available.
ISO 9001: Quality-assured manufacturing.
EN Standards: Compliant with EN 1561 (materials) and EN-GJS-400-18-LT (ductile iron).
Model Explanation
Model Example: KWP F 150-300
KWP: Series designation.
F: Free-flow impeller (optimized for slurries with solids/gas).
150: Discharge size DN 150.
300: 300mm impeller diameter.
Why Choose KSB KWP for FGD?
The KSB KWP FGD Slurry Pump combines cutting-edge German engineering with ruggedized materials to excel in the harshest slurry environments. Whether handling limestone suspensions, gypsum byproducts, or acidic wastewater, its modular design and corrosion-resistant build ensure uninterrupted performance, safeguarding productivity in critical emission control systems.
Custom Solutions Available – Specify fluid properties (pH, solids content, temperature) for tailored configurations.
