Self-priming principe

• 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.

Priming Time

• Priming time depends

of pumps Size

• Example :

− Pump type S 65

− Suction Height : 4 m

− Priming time : 83 Sec

• This table is present in

the Operating Manual

Performances in Suction use

• Correction of maximum flow when use in suction application:

− 1 m : No correction

− 3 m : max flow = approx. ¾ of pump max flow

− 6 m : max flow = approx. ½ of pump max flow

6 m 3 m 1 m (reference curve)

Product benefits

Open impeller which permits the passage of solids

Automatic lubrication of the MS to extend its life

Inspection cover for a rapid access to hydraulic in case of blocking

NRV to keep water into the pump

Wear plate for protecting pump

Motor IEC standard*

Self priming capability (6m depending to sizes)

AND ALSO : - Fill port for easy water filling - Many combinations of materials available

Flexible coupling*

*or long shaft depending versions

Lifetime lubricated bearing

10

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)

11

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

12

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)
