TURBOSAN POMPA PUMP

CENTRIFUGAL MULTI STAGE PUMPS

TECHNICAL DETAILS :

• Turbosan KAT series pumps are medium and high pressure, multi stage pumps with closed type impellers and diffusers suitable for pumping clean water and slight solids content water with low viscocity.

• Turbosan KAT series pumps have closed type impellers with curved vanes ( FRANCIS type) which generates high manometric head.

• Pump impellers statically and dynamically balanced according to ISO 1940 class 6.3, allowing vibration free and long life operation.

• As standart suction flange located on right hand side on drive end discharge flange is located on top on non drive end upon request different flange locations available.

• Bearings housings of Turbosan KAT series pumps are designed support maximum number of stages reliability. Stages which are consisting of impellers and diffusors are designed for lowest loss and highest efficiency.

TECHNICAL INFORMATION

• Discharge flange sizes : DN 50 – DN 200

• Operating temperature : -10°C + 110°C

• Ambient temperature : 40°C

• Casing pressure : Max. 30 Bar (**)

• Discharge pressure : Max. 300 m (**)

• Speed : Max. 3600 rpm

** ( Depending on pump model)

Suction flanges : ISO 7005 – 2/PN 10

Discharge flanges : ISO 7005 – 2/PN 16 – 25 upto 40

• Upon operation conditions suitable flange norm can be used.

• 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 is avalibale 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 hardened stainless steel.

• Mechanical seal is available optionally.

BALANCE DISC: Axial trust force is very important issue for multi stage pumps. Axial trust force compensated by balance disc. Balance disc is loced inside a chamber which is between bearing housing and the last stage impeller. Surface of the balance disc is coated with special hardened steel, stationary piece is coated with hard Chromium. Both faces are machined.

ADDITION TO CLASSIC MULTI STAGE DESIGN TURBOSAN HAS TWO OTHER MULTI STAGE PUMP DESIGNS

1) KAC SERIES MULTI STAGE SPLITCASE PUMPS

This series has been developed for heavy industry applications.

Equal number of impellers with counter rotation directions used.

By this design axial load generated within pump, get balanced

without need for balance disc or impeller balance holes.

Split casing design allows pump to be splitted axially.

This allows rotating elements of the pump to be dismantled

or fixed without disturbing suction and discharge flange

connections, by just opening the casing cover.

2) MULTI STAGE PUMP WITH OPPOSITE IMPELLERS :

These pumps are for high discharge pressures. Axial trust force is compensated by by back to back fitted impellers. In this design there is no need for balance disc. In special applications they used for fluids with small solid particles content.
