1、With pressure switch automatic start and stop function, built‑in bypass switch backflow function, can greatly reduce the frequent start and stop of the pressure switch. 2、Can be used in high‑temperature weather and in high‑temperature media. The temperature of the medium can reach 65°C. It also has a strong self‑priming ability. The self‑priming range of the pump can reach approx. 3m/3.3yd. 3、Low power consumption, high performance, low noise, the noise of the pump is about 55‑60db during operation, and the noise of fixed installation is lower. 4、High‑quality all‑copper motor, stable operation, adjustable pressure range of 1.7‑5.5 kg. Equipped with a variety of specifications of joints, 360° flexible installation without dead ends, convenient to achieve various directions of installation in a limited space. 5、The diaphragm is made of original raw granular material, which has high purity and long life. The pump body is made of PA66+30% glass fiber material, which has high strength, pressure resistance, and is not easy to leak.
