Pump

Pump is a device or machine that is used to move liquids from one place to another through a piping medium by adding energy to the fluid being moved and continues over time.
Pump operates with the principle of making a difference in pressure between the inlet (suction) to the exit (discharge). In other words, the pump function convert mechanical power from a power source (driving) into kinetic energy (speed), which is useful to energy in a fluid and overcome the barriers that exist throughout the drainage.

Centrifugal pumps
One type of non-positive displacement pump is a centrifugal pump that works to change the principle of kinetic energy (speed) into potential energy fluid (dynamic) through a rotating impeller in the casing.
In accordance with the data obtained, the reboiler pump debutanizer in Hidrokracking Unibon using centrifugal pumps single - stage double suction.

Classification of Centrifugal Pumps
Centrifugal pumps can be classified, based on:
1 Capacity:

     Low capacity <20 m3 / h
     Medium capacity 20 -: - 60 m3 / h
     High capacity> 60 m3 / h

2 Pressure Discharge:

     Low pressure <5 kg / cm 2
     Medium pressure 5 -: - 50 Kg / cm 2
     High pressure> 50 Kg / cm 2

3 Number / Composition Impeller and Level:

     Single stage: Consists of one impeller and the casing
     Multi stage: Consists of several series of impellers arranged in a casing.
     Multi Impeller: Consists of several impellers are arranged in parallel in a single casing.
     Multi Impeller â € "Multi-stage: The combination of multi-stage and multi-impeller.

4 Position Axis:

     upright shaft
     horizontal shaft


5. Total Suction:

     single Suction
     Double Suction

6 The direction of flow out of the impeller:

     radial flow
     Axial flow
     Mixed fllow
