BW250 Triplex Reciprocating Mud Pump | Horizontal Drilling Pump

General Introduction

The BW250 mud pump is a professional horizontal triplex reciprocating double-acting piston pump engineered for geological drilling operations. Designed with a compact structure and reliable mechanical performance, this penthouse Detroit-style piston pump serves as core drilling support equipment, dedicated to delivering stable flushing fluid for core drilling and borehole drilling projects.

Versatile in medium transmission, the BW250 drilling mud pump can handle both clean water and high-density thick mud. Featuring small overall dimensions and lightweight construction, it boasts outstanding portability and adaptability for complex construction environments, especially suitable for transportation and field operation in mountainous and remote areas.

Equipped with three cylinder bores and four gear speed stages, the BW250 mud pump supports stepless adjustable displacement and matched drilling depth based on diverse construction requirements. Beyond conventional drilling fluid supply, it also functions efficiently for cement grouting and perfusion operations, realizing multi-purpose application for drilling engineering.

Wide Application Range

The BW250 triplex mud pump is perfectly matched with various drilling rigs, widely applicable to geological exploration, engineering construction, and special drilling projects with a maximum applicable drilling depth of 1500 meters. Its main application scenarios are as follows:

• Engineering Construction Drilling: Ideal for prospecting engineering, geotechnical investigation, railway, highway, port and bridge construction, water conservancy & hydropower projects, tunnel engineering, water well drilling, and industrial & civil building foundation drilling.
• Mineral & Geological Exploration: Professional fluid supply equipment for coal field exploration, ore resource prospecting, and geological core sampling drilling.
• Water Well Drilling: Specialized for small-diameter water well drilling and rural domestic water well construction.
• Geothermal Pipe Installation: Adaptable for heat pump geothermal pipe laying and geothermal engineering drilling support.
• Foundation Piling Drilling: Suitable for small-diameter hole foundation piling and foundation reinforcement drilling projects.

Core Product Features & Working Principle

As the key supporting equipment for geological survey and core drilling, the BW250 reciprocating mud pump undertakes the critical fluid circulation work in the entire drilling process. Cooperating with matched drilling rigs, it pumps mud or water flushing fluid into the borehole continuously to form a closed circulating system.

In actual operation, the drilling mud pumped by the BW250 unit forms a protective mud coat on the borehole wall to prevent wall collapse and stabilize the drilling hole. Meanwhile, the circulating fluid carries underground rock cuttings and drilling debris back to the ground, thoroughly cleaning the bottom of the borehole. Additionally, the flowing flushing fluid provides continuous cooling and lubrication for drill bits and drilling tools, effectively reducing equipment wear, avoiding high-temperature damage, and greatly extending the service life of drilling accessories.

With stable output pressure, flexible speed regulation, strong medium adaptability, and convenient field transportation, the BW250 horizontal mud pump has become a preferred fluid supply device for 1500-meter shallow and medium-depth geological core drilling and prospecting drilling projects.

Key Advantages

• Multi-speed Adjustable Performance: 3-bore 4-gear speed design enables flexible adjustment of displacement and drilling depth to meet different engineering standards.
• Strong Medium Compatibility: Supports clean water, ordinary mud, and high-viscosity thick mud, plus applicable for cement grouting work.
• Compact & Portable: Small size and light weight solve the transportation difficulty of field equipment in mountainous and complex terrain.
• Stable Drilling Support: Efficient mud circulation ensures hole cleaning, borehole stabilization, and tool cooling & lubrication.
• Wide Applicability: Compatible with multiple drilling rigs, covering civil engineering, mineral exploration, geothermal and water well drilling scenarios.
