electric motor with three rotation speeds, representing hand (basic) and automatic (auto)

positions.

Themostimportantadvantagesofthisregulationare:

GB

- energy saving and at the same time operational cost reduction,

- reducingthenoiselevelasaresultofexcessiveow.

Thepipesmustnotbeoverstretched.

- The pump should be incorporated into piping system with the pump axis 1-1 in

horizontalposition(Fig.3).

- Toensurepumpsoperationwithminimumvibrationandnoise,thepumpshouldbe

incorporatedintothestraightpipingsectionwithlenghtofatleast5-10xD(Disthe

nominaldiameterofthepumptube)fromtheknee.

- Directionofwaterowthroughthepumpshouldmatchwithdirection,indicatedbyan

arrowonthepumpcasing(Fig.1-POS.1).

- Thepumpmustnotbeincorporatedintothesafetypumpingsystem.

- Thenominaltubediametershouldnotbesmallerthanthenominaldiameterofthe

pump.

- TheconnectingangesaredesignedfornominalpressureNP6/10(Fig.1–POS.8).

- GHN(basic,auto),GHNM(basic,auto)pumpshaveasinglehydrauliccasing(Fig.1

–POS.8).

- GHND (basic, auto), GHNMD (basic, auto) pumps have double hydraulic casing

(Fig.2–POS.11),whereatiltableapisbuilt-in(Fig.2–POS.10),tiltingautomatically,

dependingontheowdirectionofoneoranotherpump.

- Motor rotation direction in hydraulic casing is indicated on the rating plate.

- Pumps shoud be incorporated in places with easy access to enable further

maintenance works.

- Thepumpshouldbeincorporatedinawaytoprotectthemotorandconnectingcase
