Ceramic Pumps: Silicon-Carbide Vertical Units Delivered to a Hubei Desulphurisation Wastewater Project

Lead

A batch of silicon-carbide composite ceramic vertical pumps was delivered to a 2 × 660 MW coal-fired power plant desulphurisation wastewater project in Hubei, according to an industry report published in late July 2026.

Facts

The delivery. The pumps use a composite silicon-carbide ceramic for the wetted parts, with an integrated structure intended to resist abrasive and corrosive attack.

The stated application scope includes power-plant desulphurisation, zero-liquid-discharge wastewater, mining and metallurgy, and fine chemicals. (Source: the Machinery Industry Network (机经网), reported in the China Industry Development Report, 2026-07-27.)
