Cast Iron Submersible Sewage Pump

Cast Iron Submersible Sewage Pump is a device specially used for discharging sewage containing solid particles and fibrous materials. Its pump body is made of cast iron, which has good corrosion resistance and wear resistance. The pump is equipped with a cutting impeller, which can cut solid and fibrous materials during the suction process to ensure smooth discharge.

Cast iron body

Full Stainless steel

Impeller type :

Open type and semi-open type impellers

It is convenient to manufacture. When a blockage occurs inside the impeller, cleaning and maintenance are easier. However, during long-term operation, the abrasive effect of particles will cause the gap between the blades and the inner wall of the water chamber to increase, resulting in reduced efficiency, generating a large amount of vortex loss, increasing the axial force of the pump, and disrupting the stability of the liquid flow pattern in the flow channel, causing the pump to vibrate. This type of impeller is not suitable for transporting media containing large particles and long fibers. Its efficiency is approximately 92% of that of a common closed impeller, and the head curve is relatively flat.

It is applicable to various media such as sewage, clean water, wastewater with particles, and mixed wastewater containing specific insoluble solid substances. When choosing a submersible sewage pump, the appropriate pump type should be determined based on the actual type and characteristics of the medium being used.

Low noise and high efficiency operation
The coaxial structure of the Cast Iron Submersible Sewage Pump pump body and motor ensures low noise and stable operation. Due to the low noise during operation and the less vibration generated by the pump body, the equipment is suitable for noise-sensitive environments. The slow temperature rise of the motor avoids overheating, thereby extending the service life of the equipment.

Strong durability
The unique structural design of the submersible sewage pump enables it to achieve continuous operation for a long time. Because the pump and motor are coaxially connected and have a short shaft length, the mass of the rotating parts is light, which greatly reduces the load on the bearings. This design reduces mechanical wear and extends the service life of the pump, which has a longer operating life than traditional sewage pumps. This allows users to reduce the frequency of downtime maintenance during long-term use, saving maintenance costs and equipment replacement costs.

Compact structure
Compared with traditional sewage pumps, cast iron submersible sewage pumps have a smaller footprint because they work by being immersed in the liquid. This means that the pump does not require additional installation space, avoiding the construction of a dedicated sewage pump room. Users can install it directly in the sewage pool or treatment tank, saving land and infrastructure construction costs. In addition, the compact structure also facilitates installation and daily maintenance.

Low maintenance difficulty
The design of the cast iron submersible sewage pump avoids the damage caused by gasification corrosion, especially when operating in a high humidity environment, it can prevent the equipment from being corroded by water vapor. Since the pump body is completely immersed in the liquid, there is no need for filling and draining required by traditional pumps, which reduces the trouble for operators. When treating sewage, this design greatly improves the stability and reliability of the system, simplifies the operation process, and provides greater convenience for the staff.
