Any use of the pump is to be evaluated on the basis of the materials used in the pump. In case
of doubt, contact the supplier.
If the pumps are designed for special purposes the following is to be indicated:

TECHNICAL 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.
The permissible loads on the flanges appear from the following table. The values apply to
standard pumps in SG iron (GGG40).
