Quick Answer: A replacement mud pump liner can usually be identified from one or more of six references: the mud pump model, an OEM or reference part number, measured liner dimensions, a technical drawing, clear photos and nameplate information, or a physical sample. GPEPUMP supports replacement liners and related spare parts for F-Series, PZ-Series, 3NB, UNBT and other supported drilling mud pump systems, including metal/bimetal and ceramic liner options, matched pistons and broader mud pump spare-parts packages.
Which Replacement Information Do You Have?
Pump Model
The fastest starting point for standard F-Series, PZ, 3NB, UNBT and other established mud pump families.
OEM / Reference Part Number
Useful for cross-reference against model and dimensional information, especially when a maintenance BOM is available.
Measured Dimensions
Liner ID, OD, overall length, flange and seal-area dimensions can identify an unknown or unmarked liner.
Technical Drawing
A drawing provides geometry, tolerances and material requirements for engineering review and custom replacement.
Old Liner Sample
Useful for legacy pumps, discontinued configurations and replacement parts with incomplete records.
Photos / Nameplate
Useful for preliminary identification before final dimensional or engineering confirmation.
Which Replacement Route Should You Use?
| Available Information | Replacement Route | Confidence Before Final Check | What GPEPUMP Confirms Next |

Can GPEPUMP Identify a Liner From the Mud Pump Model?
| Pump Family | Typical Models / Scope | GPEPUMP Replacement Capability | Best Confirmation |
|---|---|---|---|
| F-Series | F-500 / F-800 / F-1000 / F-1300 / F-1600 / F-2200HL and supported variants | Metal/bimetal and ceramic liners, matched pistons and related fluid-end/power-end parts | Model + liner bore + PN if available |
| PZ-Series | PZ-Series mud pumps and corresponding replacement systems | Complete PZ mud pumps plus liners, pistons and other replacement parts | Exact PZ model + liner data |
| 3NB Series | Supported 3NB mud pump models | Liners, pistons, valves, seats and broader replacement parts | Model + bore + dimensions / PN |
| UNBT Series | Supported UNBT mud pump models | Liner and related replacement-part matching | Model + PN / drawing / dimensions |
| Other Supported Pumps | Legacy, mixed-brand or non-standard fleets | Engineering review based on available technical data | PN + dimensions + drawing/sample where possible |
Can an OEM Part Number Be Used to Find a Replacement Liner?
This is especially important for older rigs, rebuilt pumps and mixed fleets where previous replacement history may not match the original factory BOM.
For stronger PN matching, send:
- Pump manufacturer or existing equipment brand
- Exact pump model
- OEM or reference liner part number
- Liner bore / inner diameter
- Outside diameter and overall length
- Existing piston size
- Photos of markings or labels
- Required quantity
What if the Part Number Is Missing?
A missing part number does not stop replacement sourcing. If the old liner is available, measured dimensions can be used together with the pump model and piston information to narrow the replacement configuration.
Inner Diameter
The working bore where the piston operates. It is one of the most important replacement dimensions.
Outside Diameter
Helps confirm physical fit in the liner retention arrangement.
Overall Length
Confirms axial installation length and position.
Flange Diameter & Thickness
Critical for correct locating and retention geometry.
Seal / Groove Area
Seal diameters, grooves and contact surfaces should be measured where applicable.
Piston Size
Used to verify the liner-piston sealing pair and avoid mismatch.
Have a Part Number, Drawing or Old Liner?
Send GPEPUMP the information you already have. We can review the pump model, part number, dimensions, photos, drawing or sample details and tell you what still needs to be confirmed before quotation.
Can GPEPUMP Manufacture a Replacement Liner From a Drawing?
A useful replacement liner drawing should include:
- Inner diameter and tolerance
- Outside diameter and tolerance
- Overall length
- Flange diameter and thickness
- Locating and sealing surfaces
- Grooves, chamfers and radii
- Material requirement
- Hardness or surface requirement
- Ceramic or coating requirement when applicable
- Working pressure and pump application
Can GPEPUMP Work From an Old Mud Pump Liner Sample?
The most important rule is that an old sample must not simply be copied without considering wear. A worn liner may have an enlarged or tapered bore, damaged sealing surfaces or impact damage that no longer represents the original design condition.
Can Photos or a Pump Nameplate Be Used to Identify the Liner?
Photos are useful for preliminary identification, but photos alone are normally not enough for final manufacturing confirmation. They are most useful when they clearly show the pump identity and measurable liner features.
Send photos of:
- Pump nameplate with manufacturer and model visible
- Full liner side profile
- Both liner ends
- Stamped or engraved part numbers
- Flange and locating surfaces
- ID, OD and length being measured with calipers or suitable measuring tools
- Matching piston and any piston markings
- Wear, scoring or cracking if failure diagnosis is also required
How Does GPEPUMP Confirm Replacement Interchangeability?
Should the Piston Be Checked at the Same Time?
Important matching points include liner bore, piston diameter, piston material, sealing condition, wear pattern and operating pressure. See the GPEPUMP Mud Pump Piston guide for additional piston selection and interchangeability information.
Can the Replacement Liner Material Be Changed?
In some applications, buyers may want to replace an existing metal liner with a ceramic option, or move from one metal liner construction to another. The decision should not be based on dimensions alone. Pump model, liner bore, working pressure, mud abrasiveness, piston configuration, impact risk and maintenance strategy should be reviewed together.
| Selection Factor | What to Review | Why It Matters |
|---|---|---|
| Mud abrasiveness | Solids content, sand and current wear pattern | Higher abrasion may justify a more wear-resistant material solution |
| Working pressure | Pump model, liner bore and pressure requirement | Liner bore affects pump pressure/displacement combination |
| Piston configuration | Piston size and elastomer/material | The piston and liner operate as one sealing system |
| Handling / impact | Field installation and maintenance practice | Different liner materials respond differently to impact and mishandling |
| Maintenance strategy | Purchase price vs replacement interval | Total maintenance cost may matter more than unit price |
For current metal liner data, see the GPEPUMP Metal Mud Pump Liner. GPEPUMP also supplies ceramic liner options for supported mud pump applications.

Common Mistakes When Ordering a Replacement Mud Pump Liner
| Mistake | Risk | Better Method |
|---|---|---|
| Ordering only by a generic description such as “F-1600 liner” | The same pump family may use different liner bores | Confirm the exact liner bore and piston size |
| Using an old PN without checking the pump | Old BOMs or previous rebuilds may contain changed configurations | Cross-check PN with model and dimensions |
| Copying a worn sample exactly | The worn bore may be larger than the original design size | Use unworn surfaces, piston size and pump data |
| Ignoring the piston | A mismatch can cause pressure loss or premature wear | Confirm liner and piston together |
| Selecting liner material by price only | Service life may not match the operating condition | Review mud abrasiveness, pressure and maintenance strategy |
| Sending only a photo for final production | Photos do not reliably define machining dimensions and tolerances | Add model, dimensions, PN, drawing or sample data |
