How to Succeed in Slurry Pumping?

>Dredge Pump

As wear is a function of speed, slurry pumps should be operated at the lowest possible speed; units typically run at 1,200 rpm or less. Often, direct coupling between the pump and a low-speed motor or other drive makes the most sense. On the other hand, many other applications favour gearboxes to meet the required speed and operating point. In services where variable flow rates are required, variable frequency drives are used to provide the necessary continuous speed variation.

Critical to the engineering of the pump are heavy duty bearing frames and shafts, extra thick wall sections and easily replaceable wear parts. Total life cycle cost considerations are critical when specifying pumps for severe operating conditions, such as FGD service. High chrome pumps are ideal due to the corrosive pH of the slurry.
