Self-priming principe 5 The pump casing is specific and contains two internal chambers. Phase A : The impeller rotates in the priming chamber, which remains always filled with liquid. It creates the vacuum required for the suction of the air contained in the suction pipe. Phase B : An air/liquid mixture is created and transferred in the separation chamber, where the air is separated from the liquid, which falls by gravity into the priming chamber. Phase C : Once the suction pipe is completely filled with liquid, the pump behaves as a conventional centrifugal pump. The upper position of the suction port and the integrated non return valve make it possible to always keep the liquid inside the pump. Even after long stopped periods, the pump can start a new priming cycle without need of refilling.

Product benefits Self priming capability (6m depending to sizes) Flexible coupling* Automatic lubrication of the MS to extend its life NRV to keep water into the pump Motor IEC standard* Inspection cover for a rapid access to hydraulic in case of blocking AND ALSO : - Fill port for easy water filling - Many combinations of materials available Lifetime lubricated bearing Open impeller which permits the passage of solids Wear plate for protecting pump 9 *or long shaft depending versions

Impellers and Wear plates Impellers free passage : about ½ of the pump DN (depending on sizes) Wear plates can be changed once worn (useful for abrasive applications) 10

Automatic lubrication cartridge Provided with all Wilo-Drain SP Less warming during priming phases The spread fluid is a special hydrophobic neutral grease An electronic system provides a constant flow in during 1 year 11

Zinc Anode Wilo-Drain SP is available in Cast Iron with a Zinc Anode Special construction for SEA WATER More economic than compete pump in Stainless Steel or Bronze Zinc Anode has to be changed after a various time (between few months and a year, depending mostly of sea water temperature and salinity) 12
