Description

                                                                 useful Information

  • Dry-running capability.
  • Rapid dry self-priming up to a depth of 7 meters in a matter of seconds.
  • No seal or rotating part in contact with the pumped liquid.
  • Can be used where there are abrasive or acid fluids.
  • Wide passage for solid bodies (50 mm).
  • Flow rate proportional to number of diaphragm pulses.
  • Very simple, occasional maintenance.
  • When done always flush the pump with clean water to allow debris to move out of the pump,the reason for this is so that the debris does not harden and when the machine is started does not come crashing down damaging the diaphragm.

 

Working principle:

Libellula pumps’ flow is generated by the movement of the diaphragm and it is controlled by check valves at the suction and delivery. As the diaphragm rises away from the bottom of the casing it produces a vacuum which draws the liquid into the casing through the suction valve. When the diaphragm is on the down-stroke, the liquid is expelled through the delivery valve. The delivery line must therefore have an adequate diameter and be free to discharge the liquid being pumped to avoid pressure build up which can damage the diaphragm or the drive mechanism. The pump should be connected to pipework using sections of flexible hose to avoid transmitting the pulsations of the pump to the rest of the system.

    Recommendations

  • When starting – advance the pull start to compression stroke before pulling to start or you will break the pull start which will cost you and additional  R850.00
  • To avoid engine flooding always close petrol tap when switching engine off.
  • Check oil every 2 hours.
