Vertical Dry-Running Acid Resistant Pump Opens New Application Space for Global Tank Sump and Flue Gas Desulfurization Projects

Vertical fluid transfer equipment becomes essential for modern compact chemical plants, but most vertical pumps suffer severe damage once liquid levels drop below impellers during unmanned automatic operation. Yida Pump develops YDW series cantilever vertical acid pumps with proprietary dry-running protection structure, separating the motor above liquid level and adopting extended submerged cantilever shafts to support long-time idle operation without bearing or impeller failure.

The vertical flange direct-mount design enables direct installation on plating tanks, waste liquid pits and desulfurization absorption towers, eliminating extra pump foundation and suction pipeline layout to save 40% workshop floor space compared with horizontal pump units. All flow contact components adopt high-temperature resistant corrosion polymers, adapting to full pH range corrosive media including pickling waste water, boiler flue gas washing liquid and mineral acid slurry.

Global industrial water recycling and zero-liquid-discharge policies drive massive demand for reliable sump circulation pumps. In European and Southeast Asian metal finishing and power plant desulfurization projects, YDW vertical pumps replace traditional horizontal pump sets, simplifying automatic liquid level linkage control and reducing unexpected shutdown losses caused by liquid level fluctuation. The vertical pump line complements Yida’s horizontal magnetic and self-priming pump ranges, forming a complete horizontal-vertical product matrix covering full industrial corrosive fluid transfer demands for global engineering contractors.
