Priming pump is self-priming height, 150ZW200-15 pump, and the impeller before sealing gap, the number of revolutions of the pump, the separation chamber liquid height and other factors. Impeller before sealing the smaller the gap, the greater the self-priming height, generally taken to be 0.3 to 0.5 mm; when the gap increases, in addition to a high degree of self-absorption decreased, the Jinjiang pump, pump head, the efficiency decreased. The self-priming pump impeller height with the peripheral speed u2 increases, 125ZW120-20 pump, but to the maximum height of self-absorption, increased the number of revolutions will no longer increase the height of self-absorption, this time just shortened Self-priming time; when the number of revolutions decline, along with the decline in self-priming height. It is currently pumping of solid particles, fibers, pulp and mixed suspension and other media best trash pump. Performance range Flow Q: 8 ~ 800 m3 / h diameter DN: 25 ~ 300mm Head H: 15 ~ 80m Speed ??N: 2900 ~ 1450r / min Motor power:. 1.5 ~ 55kw 125ZW120-20 pump, self-priming pump Jinjiang No self-priming pump Limited clogging by Shijiazhuang-send pump.
