BW-250B Mud Pump Full Hydraulic Drilling Rig Supporting Pump

The mud pump for the full hydraulic drilling rig is driven by a hydraulic motor and integrated with the hydraulicsystem of the drilling rig to achieve efficient power matching and stepless flow adjustment, and can realizeremote monitoring of pump pressure, which is intuitive and convenient to operate. The use of wear-resistantmaterials such as ceramic cylinder liners significantly improves the life of wearing parts, reduces maintenancecosts, and is suitable for efficient and durable drilling operations.

Main Applications

1.Geological core drilling and engineering exploration drilling rigs, circulating mud to cool drill bits and carry rock powder inside the boreholes.

2.Foundation reinforcement, anchor rods and anchor cables, high-pressure grouting for tunnel surrounding rock leakage prevention.

3.Small water wells, geothermal shallow wells drilling mud transportation, and wall protection and grouting for pile foundation projects.

4.Underground grouting for mines to stop water leakage, and small non-excavation crossing project grouting operations.

1.Four-speed design, 4 sets of flow and pressure adjustable (maximum flow rate 250L/min, maximum pressure 9MPa), low-pressure high-flow cleaning holes and high-pressure grouting can be switched.

2.Three-cylinder piston structure, low vibration during operation, stable operation, strong stability during long-term continuous field work.

3.Commonly used wear parts, sufficient market accessories, convenient purchase of rubber cups and cylinder sleeves, low maintenance cost.

4.Compact overall structure, lightweight, suitable for small-sized drilling rigs for vehicle-mounted or site-moving construction.

Q1: Insufficient mud flow leads to poor cuttings removal and low drilling efficiency in medium & small geological exploration projects?
A1: Max flow reaches 250L/min. High-volume mud circulation efficiently carries borehole cuttings to prevent hole clogging and bit sticking, greatly improving drilling efficiency for core exploration and pile foundation investigation.

Q2: Complex ground conditions require both large flow for hole cleaning and high pressure for anchoring grouting, but ordinary pumps cannot realize both functions?
A2: 4-speed variable design provides adjustable flow and pressure with max working pressure of 9MPa. Low-pressure large flow for borehole flushing while high-pressure mode for foundation consolidation and bolt grouting, saving extra purchasing cost of another pump.

Q3: Fast-wearing spare parts are hard to source on site, resulting in frequent construction downtime under harsh field conditions?
A3: Adopts standard triplex piston structure with widely available universal spare parts such as liner and piston cup. Easy procurement and replacement effectively cut maintenance downtime.

Q4: Bulky pumps are difficult to transport and vehicle-mounted for small drill rig matching with limited installation space?
A4: Compact and lightweight body perfectly matches small-medium drill rigs, convenient for site transfer and truck mounting to fit scattered outdoor construction.

Q5: Single-function pumps only for drilling cause high idle rate and unnecessary investment waste?
A5: Dual-purpose for geological core drilling & shallow water well drilling as well as roadbed reinforcement, tunnel leakage sealing and anchor grouting, improving equipment utilization.
