Products Description
If your projects involve geological drilling, coal mining, railway or highway construction, hydropower engineering, or bridge and high-rise building construction, you will have high demands on a mud pump's adaptability, reliability, and ease of use. Our BW850/5 hydraulic piston mud pump is designed to help you advance your work more efficiently.
For those engaged in core drilling, you know that borehole cleaning, drill bit cooling, and tool lubrication are the keys to ensuring drilling accuracy and efficiency. The BW850/5 mud pump delivers these three core functions with precision: it provides stable fluid or slurry circulation, bringing rock cuttings back to the surface to keep the borehole clean at all times; at the same time, continuous medium delivery cools the drill bit and lubricates drilling tools, reducing downtime caused by equipment wear and helping you stay on schedule.
We also understand the challenges of complex working environments: whether it's extreme cold at –50 °C or high heat at +40 °C, this mud pump operates stably without shutdowns caused by temperature fluctuations. It is suitable for handling a wide range of media including freshwater, slurry, and emulsions. For more complex solutions-such as those containing specific solid particles or requiring special density or viscosity-our ball-valve configuration ensures smooth delivery without blockages or leakage, reducing operational risks.
In terms of ease of operation and use, the BW850/5 hydraulic piston mud pump adopts a compact structural design, making it lightweight and small in size. Whether for transport in narrow construction sites or for long-term fixed installations, it saves both manpower and space. For power options, we offer electric, diesel, and hydraulic motor drives-you can choose the best fit according to your site's power conditions (for example, whether stable grid power is available or if mobility is required). This flexibility eliminates concerns about "power mismatch" and truly delivers on-demand adaptability.

Application
BW850/5 hydraulic piston mud pump is widely used in geological exploration, coal mining, drilling, bridge construction, high-rise buildings, foundation reinforcement and other basic projects. Its main uses include conveying flushing media (such as fresh water, mud) to the bottom of the drill bit under pressure to cool the drill bit and lubricate the drill tool, while discharging the cuttings generated during the drilling process and bringing them back to the ground to keep the bottom of the well clean and ensure the smooth progress of the drilling operation.

Packaging & Shipping
Delivery time: 10-15days
We use professional equipment to frame the boxes. We will arrange specially-assigned person to inspect every step. Ensure transportation safety.


A One-Stop Solution
When choosing the right BW slurry pump model, you need to make a decision based on the specific usage scenario, required flow, working pressure, budget and other factors. For example, if your project is in a mine or large-scale project, you may need to choose a model with higher power and flow; while for general slurry delivery tasks, the BW160 may be sufficient to meet the needs. We offer a variety of models of slurry pumps and drilling rigs to provide you with a one-stop solution. If you have any questions, please feel free to contact us and we will recommend the most suitable equipment for you.
