BW 250

Description

BW-250 Triplex Piston Mud Pump: High Pressure and Variable Flow for Professional Drilling

The BW-250 is a horizontal, three-cylinder (triplex), single-acting reciprocating piston pump engineered for high stability and high-pressure operations. As the main equipment for geological surveys, it is designed to support professional drilling applications by supplying a consistent flow of fluid to the borehole. This circulation is essential for cleaning the hole, lubricating the drill bit, and efficiently carrying rock waste to the surface.

Key Features & Applications

• Professional Drilling Support: Specifically designed for geological core drilling and prospecting drilling with a depth of less than 350 meters.
• Triplex Piston Design: The three-cylinder configuration ensures high stability and the capacity to generate high pressure for demanding jobs.
• Highly Variable Performance: With two different liner diameter options and multiple gear speeds, the BW-250 offers a wide matrix of flow rates and pressures to precisely match job requirements.
• Durable and Multi-Purpose: While excelling in drilling, its high-pressure characteristics also make it suitable for high-lift agricultural irrigation and other industrial fluid transfer applications.

Performance Matrix

The BW-250’s performance can be adjusted by selecting a liner size and gear speed.

Using the 80mm Liner:

• Displacement (L/min): 250 / 145 / 90 / 52
• Pressure (MPa): 2.5 / 4.5 / 6*

Using the 65mm Liner:

• Displacement (L/min): 166 / 96 / 60 / 35
• Pressure (MPa): 4 / 6 / 7 / 7*

Technical Note for Buyers

• Application: Prospective buyers may note that some of the descriptive text for this model is identical to that of the BW-200. The key differentiators for the BW-250 are its superior triplex design, higher weight, and significantly more varied performance matrix, making it a more advanced option for professional use.
