Information for a Tool Quotation
- Pump manufacturer, full model and nameplate photo.
- Valve or seat reference and a photo of the component to be removed.
- Existing tool identification, complete set or individual accessory required, and quantity.

Valve Puller Tool Set inquiries for mud pump maintenance. Send the pump model, valve or seat reference, and photos of the tool and component to be removed to confirm the requested set or individual accessory.
Include available drawings or dimensions of the pulling attachment and the component to be removed. A clear photo of the existing tool helps distinguish a complete set from a replacement accessory.
Use the HHF Series Mud Pump parts category for the existing pump reference. For component identification, see the valve and seat identification guide.
