clay dredge pump

Mill sump

The FGD process begins when the limestone feed (rock) is reduced in size by crushing it in a ball mill and then mixed with water in a slurry supply tank. The slurry (approx. 90% water) is then pumped into the absorption tank. As the consistency of the limestone slurry tends to change, suction conditions can occur which can lead to cavitation and pump failure.

To reduce component wear, most centrifugal slurry pumps run at fairly low speeds - typically less than 1200 rpm. Find the optimum position that allows the pump to run as slowly as possible but fast enough to prevent solids from settling out of the slurry deposit and clogging the lines.

Applications of Rubber Lined Slurry Pumps

Non-settling slurries consist of very fine particles that do not settle to the bottom of the pipe and do not settle for very long (i.e. weeks).

The frame plate for WAJ series pumps has interchangeable hard metal or pressure moulded elastomer liners. The impellers are made of pressure moulded elastomer liners.The shaft seals for WAJ series can be packing seal, centrifugal seal or mechanical seal.
