Product details
Product Name:submersible sewage pump
Product Introduction
The submersible sewage pump is developed by introducing advanced experience in high-efficiency, energy-saving, and unobstructed sewage pumps from abroad, combined with our factory's technical strength. All performance indicators have reached the national standard level of similar products. Due to the use of a unique single channel impeller and two sets of hard alloy mechanical seals made of special materials for the dynamic seal, the motor is separated by an oil chamber, which has the characteristics of no blockage, high efficiency, and significant energy saving. It is a product that has been updated and replaced in China's pump industry.Product Features
1. Adopting a large channel anti clogging hydraulic component design greatly improves the ability of pollutants to pass through, effectively passing through 5 times the fiber material of the pump diameter and solid particles with a diameter of about 50% of the pump diameter.2. The mechanical seal adopts a dual channel series seal, made of hard and wear-resistant tungsten carbide, which has the characteristics of durability and wear resistance, and can ensure the safe and continuous operation of the pump for more than 800 hours
3. The pump structure is compact, small in size, easy to move, and easy to install, without the need to build a pump room. It can work underwater, greatly reducing project costs.
4. There is an oil-water probe installed in the pump oil chamber. When the mechanical seal on the pump side is damaged and water enters the oil chamber, the probe generates a signal to protect the pump.
5. A fully automatic safety protection control cabinet can be equipped according to user needs to monitor pump leakage, electric leakage, overload, and overheating, ensuring reliable and safe pump operation.
6. The float switch can change according to the required water level. Automatic control of pump stop and start, no need for dedicated personnel to supervise.
7. Ensure that the motor operates without overload within the range of head.
8. According to the usage scenario, the motor can adopt a water jacket external third-party circulating cooling system, which can ensure the safe operation of the electric pump in a dry state without water.
9. There are two installation methods: fixed automatic coupling installation and mobile free installation, which can meet different usage scenarios.
