Product Overview
The PX-BZWL200/31.5 is a high-pressure water injection pump station engineered for demanding water injection and pressure-relief applications in underground mining. It delivers a rated pressure of 31.5 MPa at a flow of 200 L/min, driven by 110 kW of installed power, making it well suited to tasks that require elevated pressure for deeper seam penetration and effective rock treatment. The station is built on a compact skid-mounted frame of approximately 2700 × 1200 × 1700 mm and weighs about 3500 kg, allowing it to be transported and commissioned quickly in confined underground workings. As part of the PX-BZWL series, it is configured according to project requirements and supports drilling, water injection and pressure-relief operations.
Product Description
Design priorities for the PX-BZWL200/31.5 are high-pressure capability, compact packaging and operating reliability. The elevated 31.5 MPa output enables water to be delivered into formations that require greater injection pressure, while the 200 L/min flow maintains productive progress during relief and enhancement programs. A shared base frame integrates the pump, drive and control assemblies, cutting the footprint compared with separately mounted systems and shortening commissioning time at each new location.
In service, the station is used for seam water injection, pressure relief and permeability enhancement, with the high-pressure delivery supporting improved fluid penetration into the seam. The 110 kW power package provides a balanced margin for continuous duty in routine mining operation. Final specification details such as power supply and control arrangements can be matched to site conditions, ensuring the station performs reliably across different project environments.

Applications
The PX-BZWL200/31.5 serves underground operations that require elevated injection pressure, including seam water injection, pressure relief and permeability enhancement in coal and rock formations. Its compact frame makes it particularly suitable for gate roads, working faces and other confined locations where delivery systems must move frequently. Operators benefit from a high-pressure water supply that improves fluid penetration into the seam, supports effective water hazard control and maintains productive relief programs, all within a station that can be configured to project-specific requirements.
