Product Overview

Material and Durability:
Constructed with high-density polyethylene (PE), the DENNIS-B70L pump station offers excellent sealing performance and long-lasting durability. The PE material resists corrosion and chemical degradation, making it an ideal choice for demanding sewage treatment applications.

Energy Efficiency:
Equipped with a rare‑earth permanent magnet synchronous motor (IE5 efficiency class), the DENNIS-B70L delivers over 30% energy savings compared to conventional motors. This advanced motor technology reduces electricity consumption and operational costs while supporting environmental sustainability.

Control Mechanisms:
The DENNIS-B70L features dual‑control level switches, including air pressure and float ball controls, ensuring flexible and reliable operation. These systems precisely manage sewage levels, prevent overflow, and guarantee smooth performance.

Intelligent Frequency Conversion Controller:
An intelligent frequency conversion controller provides multiple protections against jamming, overcurrent, overload, dry‑run, and freezing. The controller also supports fault display and optional remote monitoring, allowing users to supervise the pump station from a distance.

Advanced Grinding & Anti‑Clogging Technology:
The pump station is equipped with a U58HRC 440 stainless steel alloy cutter head that grinds debris into fine particles. Patented forward/reverse rotation technology automatically clears blockages and enables secondary cutting, preventing pipe clogging and ensuring uninterrupted operation.

Advantages

Sealing and Durability:
High-density polyethylene (PE) construction provides outstanding sealing performance, eliminating leaks and extending service life. PE material is resistant to corrosion and chemical attack, ensuring reliable operation even in harsh sewage environments.

Energy Efficiency:
The rare‑earth permanent magnet motor cuts energy consumption by more than 30%, substantially lowering electricity costs. Efficient operation reduces the overall carbon footprint, making it an environmentally friendly choice.

Ease of Installation and Maintenance:
The DENNIS-B70L is designed for simple installation, saving time and effort. Its compact footprint and modular design allow easy integration into existing systems. Maintenance is straightforward with accessible components, a user‑friendly layout, and a quick‑release coupling that eliminates the need to disassemble pipelines.

Customization Options:
Recognizing that different projects have unique requirements, the DENNIS-B70L offers customizable options. Users can select specific control mechanisms, motor power ratings (e.g., 1.1kW or 1.5kW), and impeller designs to tailor the pump station to their exact needs. This versatility makes it suitable for a wide range of sewage management scenarios.

Operational Conditions

The DENNIS-B70L Permanent Magnet Frequency Conversion Sewage Treatment Pump Station operates reliably under the following conditions:

• pH Value Range: Suitable for sewage with a pH value between 4 and 10, accommodating a broad spectrum of wastewater types.

• Non‑Metallic and Non‑Heavy Debris: Designed to handle sewage free from metallic objects (e.g., clips, hairpins), stones, building materials, and large fabrics, ensuring smooth and uninterrupted operation.
