Features

Waterproof Cable Base

Reinforced waterproof sealing at the motor cable entry blocks moisture ingress and meets leak-proof and moisture-resistant requirements.

Motor Overload Protector

Built-in automatic-reset overload protector cuts power when current or temperature is abnormal, preventing motor burnout.

Non-Clog Impeller Design

V-type impeller delivers maximum drainage performance for wastewater containing solids or fibers.

Food-Grade Lubricating Oil

Food-grade white oil for mechanical seals is clear, odorless, water-insoluble, non-toxic, and safe for the environment and human health.

Dual Mechanical Seals

Dual SiC (silicon carbide) mechanical seals offer oxidation, corrosion, and wear resistance with two sealing faces for reliable leak prevention and long service life.

Optional Elbow / Auto Coupling

- Elbow: Flexibly adjusts discharge direction to connect piping and optimize space.
- Auto coupling: Guide rails enable lift, disengage, and engage operations without entering the wastewater tank, improving convenience and safety.
