Customers provide maintenance services of wear-resistant and corrosion-resistant heavy pumps and accessories for local mining industries. According to the characteristics of high specific gravity and viscosity of the media on site, our senior technology has recommended a double bearing bracket structure, which not only meets the flow and lift requirements under a single bearing, but also doubles the power bearing capacity. Internal accessories are selected with high wear-resistant alloy impellers and strong corrosion-resistant rubber sheaths to meet the dual media characteristics of mining industries and successfully improve the economic and practical value for customers.
