Mine drainage and emergency dewatering
The series includes single-stage, two-stage and three-stage configurations for mine sumps, central pump rooms, deep-well drainage, emergency pumping and temporary construction drainage.
The published series supports 660 V / 1140 V supplies. Some models hold China Compulsory Certification (CCC).
Selecting a pump for water containing sand and solids
Specify particle size, solids concentration, fluid properties, continuous operating hours and pipe losses, as well as the required flow and head. Motor power alone is not sufficient for pump selection.
MGW can assess the duty point, power supply and lifting conditions and discuss repair, modification and maintenance support.
Information needed for an enquiry
Provide the target flow, total head, solids concentration and maximum particle size, shaft or sump dimensions, voltage, pipe diameter and length, running hours and planned start date.
For emergency work or short construction periods, discuss pump rental and on-site drainage services alongside equipment purchase.
