Covers six major scenarios

Hydraulic Support

Hydraulic supports are key equipment for underground safety. PINFL pumps deliver stable power for hydraulic supports with a working pressure of 31.5 MPa, ensuring rapid lifting and lowering and securing roof safety at the working face.

Solid-liquid Separation

A large amount of coal slime water is generated during coal mine production, and solid-liquid separation serves as the core link mine water treatment. PINFL high-pressure plunger pumps deliver high-concentration coal slime to filter presses at a stable pressure to realize coal slime dewatering.

High-pressure Water Jet Coal Cutting

Airborne Spraying

Coal seam water injection is an important measure to reduce coal dust and prevent coal seam spontaneous combustion. PINFL pumps inject water into coal seams under high pressure to pre-moisten the coal mass, cut down dust generation during coal mining and improve underground working environment.

Coal Seam Water Injection

High-pressure water jet coal cutting is a spark-free and dust-free safe cutting method, especially suitable for high-gas mines. PINFL pumps supply stable high-pressure water source to impact coal mass at an extremely high speed for efficient cutting.

Coal dust is a major hidden danger leading to occupational diseases and explosion accidents in coal mines. PINFL high-pressure spray pumps atomize water into fine particles to capture dust efficiently, with a dust suppression efficiency of over 90%, fully safeguarding miners' health and safety.

Directional Drilling

Directional drilling in coal mines is a core process for gas extraction, water exploration and outburst prevention. PINFL high-pressure mud pumps provide stable mud circulation power for drilling systems, ensuring drill hole cooling, cuttings removal and borehole wall stability.
