TL;DR
For NOV 14-P-220, carry the chart's configuration notes into the document review. The source treats plungers/packing above 6000 psi as a recommendation and premium modules above that pressure as a requirement. Recording one does not resolve the other or confirm the installed arrangement.
- Save the exact liner column and its footnote marks.
- Request separate evidence for the plunger/packing arrangement and module identity.
- Keep unclear source lettering and equipment applicability open until clarified.
This is a configuration-document checklist, not a conversion procedure, operating approval or replacement-part fitment statement.
Scope: which model and source does this cover?
This article reads the independent 14-P-220 Performance Chart on NOV booklet 25-101131, PDF page 30. The 12-P-160 table on the same page belongs to another model. Keep their titles and legends separate.
The booklet is general reference information. It does not establish which modules, plungers, packing or liners are installed on the unit being discussed. The pump directory provides navigation; catalog presence is not configuration approval. Collect the pump's available identity and serial information before seeking equipment-specific documents.
What is the difference between the recommendation and requirement?
They describe different evidence questions. In this chart's ‡ note, the source recommends a plunger-and-packing arrangement above 6000 psi and specifies premium modules above 6,000 psi. Preserve both meanings when translating or summarizing the note. NOV PDF page 30.
Do not soften the module requirement into an optional recommendation, or rewrite the plunger/packing recommendation as proof that those parts are already fitted. Neither phrase identifies a verified part number or confirms that the existing module qualifies as premium. Request the manufacturer's applicable configuration documents, module identification and relevant parts/drawing records.
The pressure condition belongs to this source statement. It is not a newly approved limit for a particular pump, and this article supplies no setting or authorization for operation above it.
How does a marked liner column help locate the configuration note?
It links a chart entry to its legend. The 6-, 5½- and 5-inch headings carry ‡. As a location example, the 6-inch (152.4 mm) column prints a maximum discharge-pressure entry of 6285 psi (441.9 kg/cm²), and 540 GPM (2044 LPM) at the marked 105 SPM row. NOV PDF page 30.
Save the heading, numeric fields and associated note together. These printed examples do not establish an approved duty point or an installed configuration. A performance column cannot replace evidence about the actual module and fluid-end arrangement.
The chart states 90% mechanical efficiency and 100% volumetric efficiency as its basis. Preserve them as source assumptions, not measurements of the unit. Keep this task focused on configuration documentation rather than using the example to select parts or set operating pressure.
What does the special-liner mark leave unresolved?
The chart's 9-inch (228.6 mm) heading carries **, and its ** legend describes a special liner. The size character within that legend is unclear in the printed source. Keep the clear column heading and the uncertain legend lettering as separate observations; do not silently repair the original note. NOV PDF page 30.
A special designation does not supply the liner's traceable part identity, dimensions or compatibility for the installed unit. Attach the original excerpt and ask for clarification of the note and the applicable drawing. Do not infer that a standard liner of the same nominal bore is interchangeable, or treat the booklet wording as today's stock or lead-time evidence.
Configuration evidence table and checklist
The following is an editorial handoff aid. It does not create an OEM installation procedure:
| Record to keep | Source evidence | Next document to request |
|---|---|---|
| Plunger/packing arrangement | ‡ recommendation with its pressure condition | Applicable configuration and component-identification records |
| Premium module identity | Separate ‡ module requirement | Module identity, applicable drawing and source confirmation |
| Special-liner note | ** marked heading and unclear legend character | Clarified source note and traceable liner drawing/part identity |
- Attach pump identity, available serial information and the exact source page.
- State the proposed liner size and the question requiring a decision.
- Record the installed arrangement as unconfirmed when evidence is absent.
- Preserve recommendation and requirement as separate fields.
- Attach photographs or identifiers only when actually available; do not invent them.
- List missing drawings, unresolved lettering and the reviewer responsible for clarification.
Keep the original excerpt with the packet so another reviewer can inspect the same column and legend.
FAQ
Does a plunger/packing recommendation confirm installed parts?
No. It is a source recommendation under a stated condition. Installed component identity needs separate evidence.
Can the premium-module requirement be omitted once plunger information is supplied?
No. It is a separate requirement in the cited note. Plunger documentation alone does not verify module identity or qualification.
Does the 6-inch example authorize operation at its printed pressure?
No. The example locates source fields and their note. Equipment-specific configuration and approved limits remain to be confirmed.
Can the unclear special-liner legend be corrected without source confirmation?
No. Preserve the excerpt and request clarification. The readable heading does not authorize changing the uncertain original lettering or declaring part interchangeability.

Next step
For a technical document inquiry, send pump identity, the marked chart column, original footnote and the configuration questions still open. Request component identification, module evidence and special-liner clarification separately. Have the responsible reviewer establish applicable documents before procurement, conversion or an operating decision.
