The pump adopts three-phase brushless inductive drive control technology, which saves energy and electricity. It adopts 24V low voltage DC frequency conversion technology, which saves electricity and is safer. Multi-gear frequency conversion adjustment; Sinusoidal wave technology, the current inversion vibration is smaller, the noise is lower; It has the functions of shut-off protection, water shutdown, fault alarm and automatic restart. Closed impeller design, maximum efficiency to improve the head and flow; Ceramic core is used, which is wear resistant and not easy to rust. Dual use of dilute sea water, long service life, and no copper element.
