Abstract :
Water is important element for human life. Today most people use ground
water to meet household needs. In multi-storey buildings such as apartments, they
usually use a type of multistage centrifugal pump with a closed impeller type. One
component of a multistage centrifugal popma is an impeller arranged in series that
is mounted on a shaft.This design aimed to investigate the type of multistage
centrifugal pump that suitable for Vivo Apartment with a capacity of 165 m3
/hour
designed to draw a suitable multilevel centrifugal pump to meet the needs of clean
water on Vivo Apartment using the inventor application.
The calculation results showed that the multistage centrifugal pump on
Vivo Apartment with a capacity of 165 m3
/hour had a total head of 39.76 meters
with a rotational speed of 1500 rpm having a total level of 2 and an impeller outer
diameter of 149 mm, the inside diameter of the impeller 140 mm with the width of
the outer impeller 20 mm and the inner width of the impeller 27 mm. The shaft used
was diameter of Ø 20 mm with a peg size of 6x6 mm. Images were created with the
2015 Autodesk Inventor application.
