Use the correct fluid-end drawing
Begin with the identification of the installed fluid end and the parts-list revision that applies to it. GD Energy Products' official GD 3000 and QSS guides ask buyers to locate an item in the appropriate assembly drawing, then confirm its exact part number and description. The drawing reference number locates an item; it is not a substitute for its orderable part number.
Itemize the valve, seat and other requested parts
SPM's official consumables page identifies valves and seats as component families. The cited GD assembly lists also distinguish valves, seats and springs. For your own purchase, state whether you require a complete valve assembly, a separately listed insert, a seat or another identified component. Ask for an itemized quotation rather than assuming that a description such as valve kit includes everything shown in a photograph.
Record suction or discharge position
Include the component's position exactly as your applicable drawing describes it. Some items in the named GD assemblies are listed for both suction and discharge, while covers and other entries have their own descriptions. These are assembly-specific examples, not evidence of universal interchangeability. Keep the manufacturer's part description with the request even when two components appear visually similar.
Attach evidence that resolves the purchasing question
A useful inquiry includes:
- Pump maker, full model and installed fluid-end identification.
- Exact part number, description and drawing revision.
- Documented dimensions if needed to resolve an unidentified item.
- Clear photos of markings and the requested components.
- Quantity of each item and the delivery destination.
List seals, springs, covers or retainers separately when they are required. If a component has no readable marking, explain which drawing or maintenance record you used to identify it.
Request a matched quotation
Use the well-service pump parts category or fracturing pump parts page to find the relevant inquiry route. Send your parts record through Contact Pratt Oil and ask for confirmation of the proposed items. A workshop photograph illustrates component appearance; it does not establish the correct seat geometry, pressure rating, material or fit for your installed equipment.
