Warman pumps are widely recognized for their excellent performance and durability in handling abrasive and corrosive slurries. However, even the most robust slurry pumps require regular maintenance and replacement of spare parts to maintain efficiency and extend service life.
If you are operating a Warman pump and wondering how to purchase the right spare parts safely and efficiently, this guide will help you understand everything from identifying parts to selecting reliable suppliers.
1. Identify the Correct Spare Parts
Before purchasing any spare parts, the first step is to confirm the exact pump model and part code.
Each Warman pump model—such as AH, HH, L, SP, or G series—has unique design specifications and components.
You can find the part codes in:
The pump manual or parts list supplied with your equipment
The nameplate on the pump casing
A cross-reference table provided by professional pump suppliers
Common slurry pump spare parts include:
Impeller (code 147) – controls flow and efficiency
Volute liner (code 110) – protects the pump casing
Frame plate liner insert (code 041) – resists wear
Shaft sleeve, bearing assembly, expeller, and cover plate bolt

2. Choose OEM or High-Quality Replacement Parts
When purchasing spare parts, you have two main options:
OEM parts (Original Equipment Manufacturer) – genuine parts made by Warman
Replacement parts – high-quality replacements that are 100% compatible with Warman pumps
Many professional slurry pump manufacturers, such as CNSME Pump, produce replacement parts that match Warman standards in size, material, and performance.
Aftermarket parts often provide:
Cost advantages
Shorter lead times
Customizable material options, such as high chrome alloy, rubber, or polyurethane
3. Verify Material and Quality Standards
Different working conditions—like mining, power plant desulfurization, or dredging—require different materials.
When buying parts, always confirm:
Material type: A05 (27% chrome iron), A07, A49, R55, etc.
Heat treatment process: ensures wear resistance and toughness
Manufacturer’s quality certificates: ISO, CE, or performance reports
Professional suppliers will offer testing reports, hardness data, or chemical composition certificates to prove the material quality.
4. Select a Reliable Supplier
A trustworthy supplier ensures not only part compatibility but also technical support and after-sales service.
Choose a supplier who:
Has 20+ years of experience in slurry pump manufacturing
Offers complete Warman-compatible parts range
Provides technical drawings and installation guidance
Supports global delivery and customized packaging
For example, CNSME Pump is a professional manufacturer with a full range of Warman interchangeable spare parts, exported to more than 40 countries. Our engineers provide accurate matching and quality inspection before shipment.
5. Compare Price and Delivery Time
When requesting a quotation, include:
Pump model (e.g., 6/4E-AH)
Part name and code
Material required
Quantity needed
This helps the supplier offer a precise price and delivery schedule.
Be cautious of extremely low prices—they may indicate poor-quality materials or inaccurate dimensions.
6. Installation and Maintenance Tips
After receiving your spare parts:
Check dimensions before installation
Inspect sealing surfaces for damage or burrs
Use proper tightening torque for bolts and liners
Keep a maintenance record to track part replacement frequency
Regular maintenance not only extends the pump’s lifespan but also reduces unexpected downtime.
Conclusion
Buying Warman pump spare parts doesn’t have to be complicated.
By identifying the correct components, verifying materials, and choosing a reliable manufacturer, you can ensure your slurry pump operates efficiently for years to come.
Whether you choose OEM or high-quality replacement parts, focus on precision, performance, and professional service—the three keys to a successful purchase.
