Mud Pump Crosshead Guide Plates

Crosshead guide plates are key wear and guiding components in the power end of a reciprocating mud pump. Installed in relation to the crosshead running surfaces, the upper and lower guide plates work with the crosshead to control its reciprocating movement and maintain the alignment required by the power end mechanism.

Upper and lower guide plates are manufactured according to the design and dimensional requirements of the specific mud pump. Their geometry, mounting features and running surfaces may vary between pump models, so correct identification and dimensional matching are important when selecting replacement components.

FH Petroleum manufactures both upper and lower crosshead guide plates for mud pump applications, with replacement and custom manufacturing available for different pump models and configurations.

How Upper and Lower Crosshead Guide Plates Work

In the mud pump power end, the crosshead moves back and forth between the upper and lower guide surfaces. The guide plates provide controlled running surfaces for this reciprocating movement and help maintain the position and alignment of the crosshead within the power end.

The upper and lower guide plates form part of the same guiding system, but they are separate components manufactured to their respective positions and dimensional requirements. Depending on the mud pump design, their geometry, mounting arrangement and adjustment method may differ.

Correct fit and alignment are important because wear or dimensional deviation at the guide surfaces can affect crosshead movement and the alignment of connected power end components. For replacement applications, the guide plates should therefore be matched to the specific pump design and inspected together with the crosshead and related components.

Mud Pump Models & Replacement Applications

FH Petroleum manufactures crosshead guide plates for a range of mud pump models and power end configurations. Each replacement guide plate is produced according to the dimensional and technical requirements of the corresponding pump rather than as a universal component for multiple pump models.

Our manufacturing experience includes guide plates for 3NB-series mud pumps and other commonly used drilling mud pump applications. For 3NB applications, upper and lower crosshead guide plates can be manufactured for different pump models according to the required specifications.

To identify the correct replacement guide plates, customers can provide the mud pump model, OEM part number, existing sample, technical drawing or dimensional requirements. Where drawings are provided, FH Petroleum can manufacture replacement or custom guide plates according to the specified dimensions and configuration.

Manufacturing & Quality Control

Crosshead guide plates are manufactured with particular attention to the geometry and condition of the running surfaces that interface with the crosshead. Dimensional consistency, machining accuracy and surface condition are important considerations when producing replacement components for an existing mud pump power end.

At FH Petroleum, upper and lower crosshead guide plates are manufactured according to the requirements of the corresponding pump model, customer drawing or approved sample. Machining and inspection are carried out according to the technical requirements of each component before delivery.

For custom and replacement projects, critical dimensions and relevant geometric features can be inspected against the supplied drawing or specification to verify that the finished guide plates meet the required configuration.

Custom Crosshead Guide Plates from Drawings or Samples

FH Petroleum manufactures replacement and custom upper and lower crosshead guide plates from customer drawings, approved samples, OEM part numbers or dimensional specifications. Because guide plates are model- and position-specific, each order is reviewed against the supplied technical information before production.

To request a quotation, email sales@fhpetroleum.com with the mud pump model, OEM part number (if available), quantity and whether upper, lower or both guide plates are required. Drawings and specification files can be sent as attachments, and our engineers will confirm the configuration before manufacture.
