Product Overview

Material and Durability:
The pump body is constructed with high-quality 304 stainless steel and PPO plastic, ensuring excellent corrosion resistance and anti-rust properties. The compact and ergonomic design saves installation space while delivering long service life.

Energy Efficiency:
Equipped with a rare-earth permanent magnet IE5 synchronous motor, the SJET-SE saves more than 30% of electricity compared to asynchronous motors of the same power. This high-efficiency motor reduces energy costs and supports green building standards.

Self-Priming Function:
The SJET-SE features a powerful self-priming capability with a suction lift of up to 9 meters. It easily handles long-distance and high-head water transfer applications, making it ideal for pipe pressurization, well water lifting, garden irrigation, and raw water supply.

Constant Pressure & Intelligent Control:
Built-in intelligent frequency conversion technology with a high-precision pressure sensor delivers millisecond-level response. The pump maintains stable water pressure even during simultaneous multi-point water usage, eliminating pressure fluctuations.

Quiet & Reliable Operation:
Thanks to stepless speed adjustment and advanced motor technology, the SJET-SE operates extremely quietly (typically <50 dB(A)). The pump also features high-quality wear-resistant mechanical seals to prevent leakage and enhance operational stability.

Advantages

High Efficiency & Energy Savings:
The IE5 permanent magnet motor reduces power consumption by over 30%, significantly lowering electricity bills and carbon footprint. This makes the SJET-SE an environmentally friendly and cost-effective solution for daily water supply.

Strong Self-Priming Capability:
With a maximum suction depth of 8–9 meters, the pump can draw water from wells or tanks located below pump level, eliminating the need for complex priming devices. It is ideal for areas with low inlet pressure or where gravity feed is unavailable.

Stable Constant Pressure:
The intelligent frequency controller automatically adjusts pump speed to maintain constant outlet pressure regardless of flow variations. Users enjoy comfortable, steady water pressure for showers, taps, and appliances.

Easy Installation & Maintenance:
The compact, space-saving design allows flexible installation in tight spaces. The pump is simple to connect and requires minimal maintenance thanks to its robust mechanical seals and corrosion-resistant materials.

Wide Application Range:
Suitable for household water boosting, garden and farm irrigation, industrial liquid transfer, cooling and air conditioning systems, as well as small commercial water supply for villas, apartments, schools, and hotels.
