Description

Key Features

Compact structure, light weight, small volume, beautiful appearance, is driven by a hydraulic motor, electric power or diesel engine.

Advanced product design, reasonable structure, high pressure, flow, multi-file variable, energy saving, light volume, efficiency, plant life, sage operation, easy maintenance.High quality pump parts, less wearing parts, long service life, low construction cost.

BW series mud pump is horizontal triplex grout pump with high stability and high pressure.

High-pressure pump is the key equipment for high-pressure jet grouting construction. It is mainly suitable for high-pressure jet grouting, curtain grouting, retaining cofferdam, mine plugging, wellbore retaining wall, slope anchoring, etc. Clear water can also pump high viscosity, large specific gravity cement slurry.
