【Daily Question No. 265】November 12, 2020: The suction lift of the pump is always less than the allowable suction lift. True or False ( ) Please respond within two days.
Correct. Explanation: The allowable suction vacuum level of a pump refers to the maximum vacuum level permitted at the pump’s inlet. This value is specified because if the vacuum at the pump inlet is too high, the liquid there will vaporize, resulting in cavitation and an inability of the pump to deliver fluid. The suction lift of the pump is always less than the allowable suction lift.
The allowable suction height is a limit value; therefore, the actual suction height is usually lower than this allowable value
