Features

Variable Frequency Energy Saving

4800-rpm variable-speed motor automatically adjusts power according to water usage.
Energy consumption is half of traditional constant-speed pumps.

Constant Pressure and Quiet Operation

AI algorithm monitors pipeline pressure.
Constant pressure output ensures consistent performance.
Multistage impeller structure reduces noise.

High Efficiency & Environmental Protection

Flow components are made of high polymer materials, non-toxic and odorless.
Three-blade impeller design improves efficiency.

Comprehensive Protection

• No-water protection / Dry-run protection
• Overcurrent protection
• Anti-leakage protection
• Anti-freeze protection (automatically activates if temperature < 3°C when power is connected)

---

Self-Priming Design

Multistage impeller without air chamber walls allows efficient self-priming,
eliminating traditional startup difficulties.

---

Durable and Reliable

NSK high-speed bearing, silicon carbide & graphite mechanical seal,
stainless steel pressure housing for extended lifespan.
