  • Page 16: Before Installation

    Installation CAUTION ● Do not run pump dry Do not run pump dry (operation without priming water or with a suction valve closed). Otherwise, internal parts are excessively worn by friction heat and fatal pump damage results. * If the pump runs dry by mistake, turn off power and leave it for more than Prohibit one hour to cool it down.
  • Page 17 The MX-F is not self-priming pump. Prime the pump every time the pump is operated. Do not run pump dry (operation without liquid.), or internal parts seizing or excessive wear results. ■ Maximum operating pressure Do not allow a discharge pressure to exceed the limits below.

  • Page 23 Installation ■ Discharge line 1. Support discharge piping so as not to directory weigh on the pump. 2. Lay a priming line when the pump is not under a flooded suction system. 3. Pipe resistance rises too high to obtain an intended flow if a discharge pipe I.D. is too long. Always take account of the increment of pipe resistance.
