Transferring Lime Slurry with Verderflex Pump
Challenge
A gas manufacturing company requested an effective method for transferring lime slurry from below storage tanks to tanker trucks. The company was using vacuum trucks and required a more reliable pumping process.
Solution
Due to the high specific gravity of the slurry, the solids or particles have a tendency to settle when it is left for extended periods of time. Air must be injected to ensure the lime and other particles remain in suspension prior to pumping. The slurry is very abrasive and the pump must withstand this and have the ability to run dry. In order to meet these unique requirements, Global Pumps supplied a Verdeflex peristaltic hose pump model VF65.
The VF65 with a 27.2 m3/hr maximum flow rate can comfortably handle the 20 m3/hr as required by the client. The benefit of the VF65 is that the lime slurry is isolated from all moving parts of the pump and is contained within the suction hose. With only one wearing part (the hose) exposed to the abrasive nature of suspended lime, the VF65 has less down time and maintenance then other types of pumps.
Result
Replacing the vacuum trucks with the Verdeflex peristaltic hose pump has simplified and cost-effectively streamlined the slurry transfer process for the client. The VF65’s durability prevents unnecessary down time due to reduced maintenance and mechanical failure.
