Special Service Tools

We develop two core special tools for disassembly and maintenance of mud pump fluid ends: hydraulic valve extractors and cylinder liner lifting tools, greatly cutting labor costs and downtime for equipment overhaul. Hydraulic valve extractors pull valve assemblies quickly via hydraulic power without violent knocking, preventing collision damage to valve bodies and seats. Liner lifting tools fit all liner sizes for stable and safe hoisting, allowing single-person liner replacement. Tool bodies are welded with thickened steel plates for high strength and long service life. Tools can be sold separately or bundled with full fluid end spare parts for export. They are essential supporting equipment for overseas drilling contractors and oilfield maintenance teams, custom sizes are available for special pump models.
