How to Buy Warman Pump Spare Parts: A Complete Guide for Global Users

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 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, seal ring, 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. Their 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.
