Product Description
Wilo SCP is a single-stage or two-stage non self suction
centrifugal pump with an axially separable pump housing. The water
pump housing is spiral shaped and consists of two cast iron
components that are connected together by screws fixed along the
water pump shaft. Flow range: <5200m³/h Lift range: <~190m/h Max.operating pressure at different fluid temperature : 25 bar Medium temperature range: -20~140ºC
Application:Axially split case pumps are primarily used in areas
associated with water supply, water circulation, water injection,
spray ponds, air-conditioning, water purification, sprinkler
systems, drip irrigation, fire fighting etc. | |
Summary
Wilo SCP is capable of transmiting high flow media in an
energy-eficient and efficient manner, year-round.providing reliable
water supply with extremely low operating costs. The easy to
maintain design and high efficiency throughout theentire
characteristic curve range enable the pump to operate with low
wear, eneray eficiency, and thus achieve constant watersupply.
Special features/product advantages
Efficient hydraulics for high flow rates up to 17,000 m³/h
Low NPSH thanks to double suction impeller
High process reliability and easy maintenance without removing the
pressure or suction lines
Decreased noise level and reduced vibrations
Options: Drinking water approval (KTW, ACS), innovative Ceram CT
coating
Casing
The pump casing is of volute form, cast in halves.which are bolted
together along the pump axis.Gasket paperis provided between
thesplit flangesof top and bottom casing. For accurate
locationcasing halves, bearing housings/ brackets etc. arelocated
with dowel pins.
The suction and deliverybranchesof the pump arecast integral with
bottom half casing, which alsoincorporate the mounting feet.
Tapings are drilledin suction and delivery branches for
connectingthe pressure gauges and providing casing
drain.Boresofbottom halfcasing are grooved to providelocation for
neck rings and stuffing box bushes.Tapings are provided in the top
of casing fortaking liquid seal connection on both stuffing box
regions. In other cases, alternative arrangements(see fig. 11) are
provided. Tapings are also provi-ded on the top half casing for
mounting air cockfor venting.
Neck ring
To prevent the pumped liquid from the deliveryside ofthe impeller
the pump casing is designedwith finerunning clearances around the
impellereye. These fine running clearances are essentialfor the
satisfactory performance ofthe pump andtheir periodic restoration
is necessary. Runningclearance is provided between neck rings
andimpellerneck. Neck rings are renewable to allowthis fine
clearance to be restored periodically aswear takes place. These
rings are located in thebottom half casing by a half-spigot and are
pre-vented from rotating with the impeller sincetheseare locked by
the face of split flange oftop casing
Rotating element
The rotating element consists of a shaft on towhich is keyed the
impeller orimpellers. Renewa-ble shaft sleeves abut the impeller
hub and pro-tect the shaft from corrosion and erosion. Theimpeller
is locked by sleeve nuts, which have theirthreads left/right handed
as per direction of rota-tion to prevent them from unscrewing by
therotation of the shaft.
The rotating element may be carried in deepgroove ball bearings or
in split-bush journal bea-rings, in which case ball thrust bearings
or thrustdiscs and nuts are provided to restrict- axialmovement.
Bearings are located in housings, which areattached to the ends of
the pump casing.
Stuffing box bushes (stationary part) are providedon either side
over the sleeve and located in bot-tom halfcasing. This helps in
proper guiding oftheliquid to impeller eye. Where as back face of
stuf-fing box provides support to gland packing.Logging rings
(stationary part) are provided oneither side over the sleeve,
sandwiched betweengland packing located in stuffing box
belowsealingarrangement. Loggingring providesproperstuffing box
sealing arrangement. For 2 stagepumps instead of logging ring
leak-offring /bushis provided at second stage stuffing box.For some
of the models the shaft also carrieswater thrower, oil thrower.
