Submersible Pump FAQ
What is the main advantage of a submersible pump for sewage?
The primary advantage is its ability to operate fully submerged in the fluid it is pumping. This design eliminates the need for priming, reduces noise, and is typically more efficient than other pump types for moving wastewater from lower elevations.
How do I choose the right size submersible pump for my needs?
Selecting the correct size depends on two key factors: flow rate (measured in GPM) and total dynamic head (the total height and friction loss the pump must overcome). You must calculate the volume of liquid you need to move and the vertical and horizontal distance it must travel. The Crowns SEW-500, for example, is ideal for residential complexes, while the Crowns SEW-750 is suited for larger municipal or industrial applications.
What maintenance does a Crowns submersible pump require?
While Crowns pumps are built for durability and minimal upkeep, regular maintenance is essential for longevity. We recommend a periodic inspection of the impeller for wear and clearing any debris. For pumps with mechanical seals, check the seal integrity annually. Always refer to the user manual for specific service intervals and procedures.
For a system that demands reliability and power, choosing the correct equipment is the most important decision you will make. The Crowns range of submersible pumps offers proven performance, detailed specifications to meet your exact requirements, and the durability to withstand the toughest conditions.
