CENTRIFUGAL MULTI STAGE PUMPS - …

1 CENTRIFUGAL MULTI STAGE PUMPSTECHNICAL DETAILS : Turbosan KAT series PUMPS are medium and high pressure, multistage PUMPS with closed type impellers and diffusers suitable forpumping clean water and slight solids content water with low viscocity. Turbosan KAT series PUMPS have closed type impellers with curvedvanes ( FRANCIS type) which generates high manometric head. Pump impellers statically and dynamically balanced according to ISO1940 class , allowing vibration free and long life operation. As standart suction flange located on right hand side on drive enddischarge flange is located on top on non drive end upon request differentflange locations available. Bearings housings of Turbosan KAT series PUMPS are designed support maximumnumber of stages reliability.

2 Stages which are consisting of impellers and diffusors are designedfor lowest loss and highest efficiency. Direction of rotation : Clockwise seen from drive end. In order to reduce leakage loss renewable wear ring fitted to the impellers. Axial trust which is an important concern for MULTI STAGE PUMPS , balanced by means of balance disc. Pump shafts supported by heavy duty type bearings on both sides, As standard bearings are grease lubricated. Oil lubritaion isavalibale on request, if needed oil lubricated bearing housings can be fitted with heat dissipation fins for additional cooling. KAT series PUMPS manufactured with soft packing as a standard. Soft packing is located on shaft sleeves which are made of hardenedstainless steel.

3 Mechanical seal is available DISC: Axial trust force is very important issue for MULTI STAGE PUMPS . Axial trust force compensated by balance disc. Balancedisc is loced inside a chamber which is between bearing housing and the last STAGE impeller. Surface of the balance disc is coated withspecial hardened steel, stationary piece is coated with hard Chromium. Both faces are X 5 Number of stagesDischarge diameterPump typeFIELDS OF APPLICATIONST urbo - KAT series PUMPS are suitable for Public and industrial water supply Booster systems Boiler feeds Fire fighting units Marine industries Mining industries Sprinkler systems Chemical and Petrochemical plants Power plants Irrigation(30)Part 61) KAC SERIES MULTI STAGE SPLITCASE PUMPSThis series has been developed for heavy industry number of impellers with counter rotation directions this design axial load generated within pump, get balancedwithout need for balance disc or impeller balance casing design allows pump to be splitted allows rotating elements of the pump to be dismantledor fixed without disturbing suction and discharge flangeconnections, by just opening the casing MULTI STAGE PUMPSTECHNICAL INFORMATION Discharge flange sizes: DN 50 DN 200 Operating temperature: -10 C + 110 C Ambient temperature : 40 C Casing pressure : Max.

Axial trust force is compensated by by back to back fitted impellers.

5 In this design thereis no need for balance disc. In special applications they used for fluids with small solid particles content.(31)CasingCast iron ( GJL 250) (EN-JL 1040)Cast iron ( GJL 250) (EN-JL 1040)ImpellerBronzeCast iron ( GJL 250) (EN-JL 1040)DiffusorCast iron ( GJL 250) (EN-JL 1040)Cast iron ( GJL 250) (EN-JL 1040)Wear ringBronzeCast iron ( GJL 250) (EN-JL 1040)ShaftStainless steel (AISI 420) ( )Carbon steel ( )Shaft sleeveStainless steel (AISI 420) ( )Stainless steel (AISI 420) ( )Balance discHardened steel filling + Chromium plated Hardened steel filling + Chromium platedShaft sealingSoft packing / Mechanical SealSoft packing/ Mechanical SealPaintingRAL 5010 RAL 5010 Capacity (m3/h)Capacity (m3/h)Manometric Head (m)Capacity (m3/h)Capacity (m3/h)
