Can this Stainless Steel Submersible Sewage Pump do?
No, absolutely not! Even if it is idling for a short time, the submersible pump will suffer damage. When the pump is running, the mechanical seal needs to be lubricated and cooled. If there is no liquid, the mechanical seal will overheat and rupture, which may cause the pump to leak and liquid into the motor. The motor may also burn out, as this requires fluid cooling during operation. Our recommendation is to ensure that the pump and motor are always submerged in water during operation. There are two main methods to ensure that the pump only runs when immersed in water. First, the pump should only be turned on and off manually when the operator can clearly see the oil pan. Second, install a float switch on the pump, once the fluid drops to a specific level in the cavity, the switch will automatically shut down the pump. If you think idling is inevitable, then please contact us and we will try to choose a more suitable pump for your application.
How do I know which size of the Small Submersible Pump is suitable for my application?
A clear understanding of the pump system is required to make an accurate selection. The main information required includes; application description, pipe hole, fluid, flow rate, and pressure/head. With this information, the size of the pump can be correctly determined to ensure that the pump can provide the required flow and pressure, and can also operate at the best efficiency, thereby reducing the life-span cost. Knowing whether the pump runs intermittently or continuously, you can also select the correct motor speed. For example, a pump that runs continuously 24/7 will require a 4-pole motor instead of a 2-pole motor. Reducing the operating speed of the motor and increasing the size of the pump will reduce the wear of the motor and pump, thereby reducing maintenance costs during its life
