- Simple structure for easy maintenance and disassembly
- Smooth operation, minimal vibration, and low noise
- It can deliver high concentration and high viscosity suspended slurry
- The drilling fluid flow is stable. It has no over-current, pulsation, and remains stirred.
- The discharge pressure is not proportional to the speed. The displacement can be adjusted easily by the shifting mechanism or motor.
- The pumps usually have a high self-absorption capability, and they can suck the liquid directly without the bottom valve.
Applications of Dragon Mud Pumps
Oil and Gas Exploration
This is its core application. The pump is explicitly defined as a "mud pump" for drilling operations, particularly suitable for: Shallow well drilling operations, providing the circulating power needed to cool, lubricate, and carry cuttings for the drill bit.
Well Services and Workover
Its reliable pressure and flow output make it an ideal choice for well intervention, well killing operations, and hot washing operations. The inclusion of 1502 high-pressure swivel joints in some used equipment packages also strongly suggests its history of use in high-pressure well service lines.
Mining and Resource Extraction
The robust fluid end design, especially the optional ultra-wear-resistant zirconia ceramic liners, makes this pump highly suitable for handling the abrasive slurries and pulp commonly encountered in mining operations.
Heavy Civil and Industrial Pumping
Leveraging its high power and high-pressure capabilities, the pump is equally applicable to large-scale long-distance water transfer, pipeline pressure testing, proppant pumping for hydraulic fracturing, and other industrial applications requiring high-pressure fluid transfer.

- Check the oil level at the power end after stopping the pump.
- Observe the working conditions of the cylinder liner and piston. If the leaked mud is found to exceed the normal limit, new cylinder liners and pistons must be replaced.
- Check the cylinder liner cavity, if there is a large amount of mud precipitation, it should be cleaned.
- Check whether the water in the water tank of the spray pump is sufficient and replenish it in time, replace the cooling water when it is contaminated, and clean the water tank at the same time.


- Check whether the inflation pressure of the exhaust air bag meets the requirements.
- Regularly check the reliability of the safety valve.
- Loosen the piston rod clamp every day, turn the piston about a quarter of a turn, and then tighten the clamp.
- Before tightening the cylinder head and valve cover, fill the thread with grease first, and check whether there is any looseness every 4 hours.
