Technical details and source references

Confirm the installed model, drawing revision and dimensions before ordering. Catalogue quantities do not indicate current stock.

Reference documents and scope

  • S1 — Mud King Products, Mud Pump Expendables / Triplex Fluid End Parts (source catalogue edition undated). Reference file: EMSCO-MK-美国泥浆泵.pdf.

PDF page numbers count from the first page of each reference file. Brand names identify the equipment or catalogue source. A listed number does not establish interchangeability, original-manufacturer authorisation, stock or a delivery commitment. Send the nameplate, complete reference, quantity and drawing revision for a parts review.

For a Oilwell A-850-PT mud pump parts enquiry, the complete component reference is more useful than the pump model alone. The Mud King Products catalogue separates expendable parts by nominal size, component family and installed arrangement. This guide transcribes the identifiable supplier-number entries associated with Oilwell A-850-PT, with their original page and table context, so a buyer can assemble a clearer maintenance RFQ.

Liner-OD Options and A-Series Module Boundaries

The A-850-PT sheet uses MK-0289-series liner references and mentions a separate small-OD liner pattern, MK-0285-XX. The letters XX are an unresolved size suffix in a catalogue pattern, not a complete orderable number. Keep outside-diameter arrangement and nominal liner size together when asking for a replacement.

The conventional A-series module list restricts liner-adapter nut MK-10-303-092 to A850-PT/A1100-PT. Its paired A1400/A1700 alternative is not assigned to this model. The L-shaped section likewise lists complete assembly MK-8487-A for A-850-PT/A-1100-PT and a separate large-OD liner-retainer nut. These explicit model and liner qualifications remain attached to the relevant references.

Read the catalogue reference correctly

The accompanying reference list covers the identifiable number-bearing cells in the relevant source tables, not a complete original-manufacturer bill of materials. MK and MKG identify supplier catalogue references; their prefixes, punctuation and combined suffixes are retained. A value marked N/A or left blank is not replaced by an invented number. A shared model heading records the catalogue scope and does not by itself confirm interchangeability on an individual pump.

Information to send for parts matching

Send the pump nameplate and serial number, full reference including its prefix, required quantity and a photograph of the installed or removed component. For liners and pistons, add the nominal size and sealing arrangement. For fluid-end hardware, identify the module configuration and whether an individual component or a studded assembly is required. Keep any original equipment drawing number as a separate field rather than stripping the supplier prefix to assume an OEM match.

Review mud pump spare parts matching, compare liners, pistons, valves and seats, or send Pratt Oil a parts list for review. Matching and availability require confirmation; these references do not establish authorisation, inventory or a delivery promise.
