Key Features & Advantages
- Full Head, Wide Voltage Design: A key performance feature allowing stable operation across the pump’s entire performance range. It is specifically designed to withstand power supply fluctuations, ensuring reliable operation in areas with unstable grid conditions.
- Single-Phase (WQD) Models: Stable operation within 160V–230V.
- Three-Phase (WQ) Models: Stable operation within 330V–380V.
- National Standard Motor: Equipped with high-efficiency, durable motors manufactured to national standards, ensuring consistent power and reliability for demanding sewage-handling tasks.
- Premium Brand Bearings: Features high-quality bearings that minimize friction and wear, contributing to smoother operation, lower noise levels, and extended service life under the stress of pumping solids-laden fluids.
- Silicon Carbide Mechanical Seals: Utilizes wear-resistant silicon carbide (SiC) seals. This material provides exceptional durability and resistance to abrasion from sand, grit, and other solids suspended in sewage, significantly enhancing sealing integrity and preventing leakage.
Model Number Instruction
The model code specifies the pump’s type and key performance parameters:
- WQ: Submersible Sewage Pump (Three-phase)
- WQD: Submersible Sewage Pump (Single-phase)
- First Number(s) (e.g., 10, 15): Rated Flow (m³/h)
- Second Number(s) (e.g., 9, 11, 15): Rated Head (m)
- Third Number (e.g., 0.55, 0.75, 1.1): Motor Power (kW)
Example: WQD10-9-0.55= Single-phase iron shell sewage pump with 10 m³/h flow, 9m head, and 0.55kW power.
