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 Gardner Denver PJ8A 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 Gardner Denver PJ8A, with their original page and table context, so a buyer can assemble a clearer maintenance RFQ.

Shared Expendables Sheet and Liner-OD Matching

PJ8A appears alongside PAH (All Models) on the expendables sheet. The source distinguishes small-OD and large-OD liners rather than providing one universal liner code. For a 3-inch bore, the respective entries are MK-0189-30 and MK-0193-30, while the packing column lists MKG-0266. Measure or identify the installed liner outside-diameter arrangement before preparing the replacement list.

The same sheet lists MK-0193 for the clamp-type piston rod, with extension rod MK-16-0192 and clamp MK-24-0191. These are supplier references from that particular table. The later PAH-only module drawing is not promoted here as proof of PJ8A module compatibility; supply the PJ8A nameplate and its own module markings if a fluid-end assembly is required.

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.
