Critical Factors When Choosing Submersible Slurry Pumps
Specifically, a number of essential factors should be considered when selecting the correct submersible slurry pump, whether it is for dewatering, desilting or dam cleaning. The first point is the quantity of product that needs to be transported. The flow rate or tonnage will determine the size of the pump to start. Then the discharge head, which will determine the power required and the pump hydraulics. Equally critical, is the product characteristics, for instance, clean water, dirty water, light slurry, heavy slurry.
On product characteristics, Gomes indicates that, when pumping clean water with a typical submersible pump, all particles and contaminants must be kept removed. Conversely, should the concentration of slurry be higher, a slurry submersible pump will offer longevity of the wear parts and is ‘downwards’ compatible, albeit at a slight compromise in discharge pressure capabilities and efficiency losses.
