Lime Crusher Sump Pump Upgraded.
Solids Buildup And Abrasion Stopped.
At a major co-generation plant, the lime crusher area sumps were a chronic maintenance problem. Sumps protect conveyor belts, motors and low-lying equipment from seepage, rainwater and washdown. Limestone rock and fines are constantly falling off the belts.
High capacity centrifugal pumps are limited when handling abrasive slurry at low flow rates. The sump acts as a clarifier, allowing the “quiet” water to drop its solids while the sump fills to a pump high level “on” point. Previous vertical slurry pumps had been chronic maintenance headaches, prone to silting-in and abrasive wear.
A 3 inch Pitbull Submersible Pump, with its inherent design features, solved the maintenance problems. The most important of these is that Pitbull pumps cycle automatically to match the incoming flow rate. Sump level is kept lower, continually removing solids from the bottom instead of waiting for the centrifugal pump high level “on” point.
And because the design keeps internal velocities very low, abrasive wear is virtually non-existent.
Pitbull pumps have provided a reliable, low maintenance service in this heavy abrasion environment for over four years, and still pumping.
