DESCRIPTION
The noise level indicated is the airborne noise including the motor. The noise depends on the motor
type supplied, as the noise from the pump can be calculated as the noise level of the motor + 2dB(A).
The noise level is for pumps with electric motors.
The capacity of the pump appears from the name plate on the pump. If the pump has been delivered
without motor, the pump capacity is to be indicated on the plate when mounting the motor.
