| Summary: | Water pump is a device to transport liquid from one place to another. This device
is used in most of household in Indonesia. Small-scale water pump which is
effective to lift more discharge is generally used. The ones that are most preferred
are centrifugal types which having low absorbability. Pump performance is
limited by pressure level in real electrical power whereas pump efficiency is
influenced by head and discharge. The research aims to find out the efficiency of
five distinct brands of home water pumps which are broadly distributed in market.
At the end of the research, one out of five home water pump brands will be
selected as the optimal working home water pump with low operational expense
based on the utilizing age.
The result of the research shows that the maximum efficiency value among
various brands of water pump is diverse. Each value is arranged as follow from
water pump A to E orderly: 12,922%, 13,485%, 12,823%, 14,751%, and 3,379%.
Discharge and pressure of pump that which is produced at the maximum
efficiency i.e. A, B, and C with the same pressure of 10,60 m 17,167 l/mnt
