The Necessity of Equipping Sewage Pumps with Pump Control Cabinets

During customer inquiries about sewage pumps, Dingfei Pumps has found that many users are unaware of

 the necessity of equipping their sewage pumps with pump control cabinets, often leading to pump failures

 due to various reasons. Today, we'll focus on four reasons why equipping sewage pumps with pump control 

cabinets is essential:

1. The Need for Automatic Control: Pumps are generally required to operate automatically according to user 

requirements (such as liquid level, pressure, etc.) even when unattended. This cannot be achieved without a 

control cabinet.

2. The Need for Safe Operation: Using control elements, such as buttons, to start and stop the pump ensures 

operator safety. Furthermore, the rapid action of contactors ensures good consistency in the three-phase power

 supply, meeting the electrical characteristics of the motor.

3. The Need for Control Functions: Some users require uninterrupted water supply for production and often equip

 their pumps with a standby pump. This is a one-for-one backup control system. Some even require two-for-one or 

three-for-one backup control. The standby pump must automatically start in case of a working pump failure, and 

some users also need timed automatic switching. Without a control cabinet, these tasks are difficult to accomplish. 

For example, larger power water pumps (15kW and above) require reduced-voltage starting, which also necessitates

 an electrical control cabinet.

4. Protection Function Requirements: We know that electric motors cannot be overloaded for extended periods or 

operate with a single phase loss. Therefore, overload, short-circuit, and single-phase loss protection are required. 

Submersible sewage pumps also need leakage protection, etc. These protection functions are all controlled and 

implemented by the electrical control cabinet.

In summary, if a sewage pump requires a water pump control cabinet, please carefully select a suitable matching 

water pump control cabinet. For more information on sewage pump selection and technical issues related to sewage

 pump matching water pump control cabinets, please consult [the relevant authority/organization].
