Because the temperature rise is so low, it is also possible to continuously operate smaller motors (our PE1 & PE2 pumps) for dry well applications without the need for cooling. Add to this an increased bearing design life, reduced shaft deflection and increased shaft fatigue safety factors, and you have a highly robust and reliable submersible motor design.
When it comes to hydraulic reliability, the key is blockage and wear resistance coupled with easy adjustment to maintain optimum operating conditions. The ABS submersible sewage pumps XFP range makes use of our new Contrablock Plus impeller design with adjustable bottom plate to ensure dependability throughout the pump lifetime. Larger pumps also use optimised closed impeller designs to give the best balance between reliability and energy consumption.
