1. Product Overview

2. Main Structure & Materials

• Main cylinder body: High-strength alloy steel forging, quenched and tempered, high tensile strength, resistant to frequent pulling load;

• Hydraulic seal assembly: Wear-resistant fluorine rubber sealing rings, suitable for long-term high-pressure hydraulic operation, no oil leakage;

• Grab claw: Precision machined alloy steel, flexible opening and closing, firm clamping on valve core shoulder without slipping;

• Auxiliary positioning sleeve: Copper alloy guide tube, avoid scratching the inner wall of valve seat during pulling.

3. Working Principle

1. Insert the positioning guide tube into the pump valve hole to center the tool;

2. Extend the grabbing claw into the valve cavity and lock the shoulder of valve assembly tightly;

3. Manually pump hydraulic oil into the hydraulic cylinder to generate axial pulling force;

4. Steadily pull out the stuck valve core, valve spring and valve plate integrally;

5. Release hydraulic pressure to retract the pull rod and take out the complete valve assembly for replacement or cleaning.

4. Core Performance Advantages

1. Labor-saving & high pulling force

   Hydraulic power replaces manual knocking and prying, small operation force but large pulling tonnage, easily take out severely stuck mud valves after long-term operation.

2. No damage to fluid end parts

   Centralized positioning structure avoids eccentric pulling force, effectively prevent scratch, crack and deformation of valve seat, pump cavity and valve body, greatly reduce fluid end maintenance loss.

3. Integrated portable design

   Light split structure, easy to carry to well site, narrow pump side space can operate normally.

4. Wide matching adaptability

   Multiple interchangeable claws and guide sleeves, compatible with most mainstream mud pump suction/discharge valve specifications.

5. Safe operation

   Slow uniform pulling force, no sudden pop-out of valve assembly, avoid mud splashing and component flying injury risks.

5. Main Application Scenarios

1. Routine maintenance of mud pump fluid end: Replace worn valve rubber, valve plate and spring;

2. Disassembly of stuck valve assemblies blocked by sediment, rock debris and thick mud;

3. Horizontal directional drilling, oilfield drilling, foundation engineering mud pump daily overhaul;

4. Fast disassembly without removing discharge manifold and cylinder flange, greatly shorten maintenance downtime.
