### Step-By-Step Guide for Pumping Tips for Non-Settling Slurries.
#### Step 1: Choose the Right Pump.
Select a pump that is specifically designed for handling non-settling slurries. Look for pumps with a larger impeller size and slower operating speeds, as well as features such as recessed impeller vanes or vortex impellers to prevent clogging.
#### Step 2: Ensure Proper Suction and Discharge.
Make sure the pump is located close to the slurry source to minimize pipeline length and reduce friction losses. Use larger diameter pipes for both suction and discharge lines to reduce velocity and turbulence, which can cause settling.
#### Step 3: Monitor Slurry Properties.
Regularly monitor the characteristics of the slurry, such as particle size, concentration, and density. Adjust the pump settings accordingly to maintain optimal performance and prevent settling.
#### Step 4: Maintain Proper Pump Speed.
Run the pump at a speed that matches the flow rate of the slurry, avoiding excessive speeds that can lead to settling. Use variable frequency drives or throttling mechanisms to easily adjust the pump speed as needed.
#### Step 5: Prevent Air Entrapment.
Ensure that the pump is properly primed before start-up to prevent air entrainment in the slurry. Consider using air release valves or vacuum priming systems to remove any trapped air in the system.
#### Step 6: Regular Maintenance and Cleaning.
Perform routine maintenance on the pump to prevent clogging and ensure smooth operation. Clean the pump and piping system regularly to remove any buildup or sediment that could cause settling.
By following these steps and implementing the pumping tips outlined in the guide, you can effectively handle non-settling slurries and maintain optimal performance of your pump system. Remember to monitor the slurry properties, choose the right pump, and maintain proper operating conditions to prevent settling and ensure efficient pumping.
