Simply put, the difference between sewage pumps and submersible pumps is that sewage pumps are mostly installed on the ground and can be used to treat sewage containing particulate impurities. Submersible pumps can be directly submerged, but can only be used to deal with clean water and similar media. Of course, the difference between the two is more than that, you can look at the small edition for you to sort out the following differences.
The use of sewage pump and submersible pump is different
Submersible pump suitable for some special process requirements, such as leakage, fluid medium special, etc., the price is more expensive. Sewage pumps are generally used for regulation, but also switch volume, such as: fan coil end.
Sewage pump and submersible pump switch form is different
The submersible pump is driven by the coil and can only be turned on or off. The drive of sewage pump is generally driven by motor, open or close action to complete a certain amount of time simulation, can be adjusted.
Sewage pump and submersible pump have different working properties
Submersible pump general flow coefficient is very small, and the working pressure difference is very small. For example, the general flow coefficient of 25 caliber submersible pump is much smaller than 15 caliber electric ball valve. Submersible pump is driven by electromagnetic coil, relatively easy to be damaged by voltage shock. Equivalent to the role of the switch, is on and off two functions.
Sewage pump is generally driven by motor, more resistant to voltage impact. Submersible pump is fast on and fast off, generally used in small flow and small pressure, the switch frequency is required to be large in the place of sewage pump vice versa. The opening degree of the sewage pump valve can be controlled, and the state is open, closed, half-open and half-closed. The flow rate of the intermediate pipe can be controlled, while the submersible pump cannot meet this requirement.
Submersible pump can be reset by power, sewage pump to such a function needs to add a reset device.
