🔧 I. Key Features
1.Efficient Solids Handling
Semi-open impeller design: Capable of handling solid particles up to 10 mm in diameter (e.g., silt, gravel); suitable for sewage discharge and surface/groundwater transfer.
Flow and Head: Rated flow and head capacities designed to meet high-flow, medium-head drainage requirements.
2.Durable Construction and Sealing Technology
Cast iron construction: Pump casing made of EN-GJL-250 cast iron; impeller made of EN-GJS-500-7 ductile iron; corrosion and impact resistant.
Dual mechanical seal system: Main shaft seal features SiC/SiC (silicon carbide) material; supports quick on-site replacement without special tools, significantly reducing leakage risk.
IP68 protection rating: Fully waterproof design suitable for submersible installation (maximum depth of 7 meters).
3.Smart Motor and Safety Protection
High-efficiency three-phase motor: Rated power output; Insulation Class F (155°C); equipped with deep-groove ball bearings; supports Direct-On-Line (DOL) starting.
Multiple protection mechanisms:
Overload protection (PTOC standard) and locked-rotor protection (torque: 11–12 Nm).
No humidity sensor, but features a built-in capacitive sensor to detect liquid impurities.
4.Flexible Installation and Easy Maintenance
Multi-scenario adaptability: Supports free-standing installation or automatic coupling systems; connection type: NPT thread.
Pre-installed cable and plug: Comes standard with a 10-meter H07RN-F cable and plug; designed for quick disconnection and watertight integrity.
