Product Description
The external horizontal series integrated sewage lifting pump station provides comprehensive sewage discharge solutions primarily for large commercial complexes such as subway platforms, underground transportation hubs, public institutions, shopping malls, underground markets, and hotels. Sewage is collected in the tank to a set level and lifted to the main sewer or municipal manhole using dry-installed cutting sewage pumps. The system is typically configured as an IP68 2860rpm sewage lifting station, ensuring high operational efficiency and durability in demanding environments. Multiple tank volume combinations are available, from 500L to 1000L, 1500L, etc. The tank is made of corrosion-resistant, environmentally friendly polyethylene (PE) with excellent sealing. Single tank volume is approximately 500L, and multiple tanks can be connected in parallel. This is a typical 500L~1500L large capacity sewage lifting station.
Product Features
External Dual-Pump Design: Configured with dual pumps for redundancy. If inflow exceeds single-pump capacity, the other acts as a supplementary pump. Motors are located outside the tank, bolted on, avoiding immersion in sewage, facilitating maintenance and heat dissipation, and enabling easy observation and repair. This reflects the high-reliability design of an integrated sewage lifting pump station.
Horizontal Layout: Adopts a horizontal layout, more suitable for space-constrained installations, compact and space-saving. Pumps can be horizontal or vertical.
High-Efficiency Clog Prevention: Uses an innovatively designed dry-installed helical cutting pump, significantly improving debris pass-through capability, non-clogging, and easy maintenance.
Motor Protection: The 500L~1500L large capacity sewage lifting station employs motors capable of withstanding frequent starts, with IP68 protection class, operable fully submerged. Features leakage protection, overheat protection. Maximum pump start frequency is 20 times/hour. Meets the stringent requirements of an IP68 2860rpm sewage lifting station.
Low Operating Noise: Tank interfaces and pipelines use rubber hose flexible connections for effective noise and vibration damping.
Environmentally Friendly and Energy-Saving: Sealed tank design with ventilation and deodorization devices prevents odor emission; equipment starts/stops automatically based on liquid level, saving energy.
Easy Maintenance: Fully installed and tested in the factory, installed as a complete unit on-site, simplifying construction. The external design separates the motor from sewage, facilitating observation and maintenance.

FAQ
Q: What does "dry" installation mean for an "external" pump, and what are its advantages?
A: "Dry" installation means the motor part of the pump does not contact the conveyed sewage, typically installed outside the collection tank or in a separate dry well. Advantages include a dry, clean working environment for the motor, better heat dissipation, safer and more convenient maintenance without contacting sewage, and usually longer motor life. This is a common configuration for large integrated sewage lifting pump station units.
Q: Why would large commercial complexes choose this external horizontal sewage lifting pump station?
A: Because such venues have large sewage volumes and require highly reliable, high-capacity, easily maintainable equipment. The external dual-pump design provides redundancy, ensuring uninterrupted drainage; large-capacity tanks (e.g., 500L~1500L large capacity sewage lifting station) buffer peak flows; external design facilitates maintenance without disrupting business operations; horizontal layout saves underground space.
Q: The unit specifies a maximum pump start frequency of 20 times/hour, which is relatively low. Why?
A: This is because large units have very large tank volumes, requiring a longer time for sewage to fill the tank. Consequently, the interval between pump starts/stops naturally increases, and the start frequency decreases. A lower start frequency helps reduce mechanical wear and electrical stress on the equipment, extending the life of pumps and control components, aligning with the need for long-term stable operation of a large IP68 2860rpm sewage lifting station.
