Tips to Keep Your Wastewater Pump Free from Blockages

Managing wastewater pumps presents operational challenges. The core question addressed: How do I keep my wastewater pump free from blockages? Here are practical tips to maintain optimal pump performance.

Tip #1: Consider the Design of the Impeller

Before purchasing a pump, evaluate whether the impeller design suits your specific application. Since changing impellers typically requires complete pump replacement, this assessment is critical beforehand.

Three primary impeller types exist in wastewater applications:

• Vortex impellers: Largest free passage, accommodating larger solids
• Single vane impellers: Moderate performance characteristics
• Multi-vane impellers: Smallest free passage, suited for treated wastewater

Selection involves weighing the pump’s efficiencies, energy usage and more alongside impeller type.

Tip #2: Remove Floating Solids in Pumping Pits

Wastewater systems typically employ multiple submersible pumps at pit bottoms. When water reaches specific levels, pumps activate to restore original water heights. However, floating solids cannot be extracted, instead forming masses that eventually sink and obstruct pumps. These particles additionally risk tangling float switches. Solutions include limiting solids introduction or employing a vacuum tanker lorry to pump out the pump station remains periodically.

Tip #3: Switch the Duty Pump Periodically

Rotating pump duties extends system longevity. Using a single pump continuously allows solids to accumulate around idle equipment. Upon reactivation, solids accumulate around it. These solids are likely to get sucked into the pump when it’s switched on after a long time, leading to a blockage.

Tip #4: Service Wastewater Pumps Regularly

Establish consistent maintenance schedules. During servicing, technicians should remove the pump parts and clean the impeller to remove anything accumulated, ensuring long-term efficient operation while reducing repair frequency.
