OPI 700HDL Mud Pump Parts: Liner Packing and Rod-Connection References

For a OPI 700HDL 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 OPI 700HDL, with their original page and table context, so a buyer can assemble a clearer maintenance RFQ.

Liner Packing and Rod-Connection References

The 700HDL expendables sheet lists liners from 4 to 7 inches with size-specific packing references. For example, the 4-inch liner is MK-0481-40 and its packing is MKG-0753, whereas the 7-inch row uses MK-0481-70 with MKG-0756. The packing code should travel with the liner size; a request for a generic 700HDL liner seal leaves an important selection detail unresolved.

The rod table separates clamp-type and thread-type arrangements. Its piston-rod entries are MK-0482 and MK-0481 respectively, with different sub-rod references. A photograph of the installed connection is therefore more useful than choosing from the model name alone. The valve table also keeps the seat, spring, insert and puller head in separate columns, so these should be separate RFQ lines.

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.
