I. Structural Design Features
Specialized Heat-Dissipating Housing: The outer casing is cast from 304 stainless steel, offering excellent thermal conductivity to facilitate rapid cooling during prolonged operation; the stainless steel material also provides corrosion and rust resistance, extending the housing's service life.
Main Structure: The core of the pump is primarily constructed from cast iron, ensuring high structural strength, robust pressure-bearing capacity, and operational stability; it is suitable for most standard sewage applications while offering cost-effective manufacturing.
National Standard Flange Connection: Supports standard flange installation for a secure, well-sealed connection; also compatible with national standard internal thread connections to meet diverse engineering installation requirements.
II. Sewage Handling Performance Advantages
Features a stainless steel open impeller with a specialized mechanical design that creates a wider flow passage; capable of rapidly expelling solid particles and long-fiber debris without impeller jamming or clogging, offering excellent resistance to entanglement and superior sewage discharge capability. The motor and pump share a coaxial, integrated design for submerged operation, resulting in a compact footprint and facilitating easy installation and maintenance.
III. Upgraded Durability Features
Imported Bearings: Equipped with high-precision bearings that ensure smooth, high-speed rotation with low noise and minimal vibration-induced wear, effectively extending the unit's overall service life.
Multi-Layer Sealing System: The oil chamber utilizes a double-sided fluororubber mechanical seal, while the outer chamber features a single-sided fluororubber mechanical seal, significantly reducing friction-related water ingress issues; combined with acid/alkali-resistant fluororubber seals and corrosion-resistant cabling, the system ensures reliable sealing during long-term underwater operation.
Safety Protection Design: The motor utilizes Class F insulation with high-temperature resistant copper wiring.
