The AD pump should be attached to the plant piping using a flexible hose/coupling on both the intake and
discharge ports of the pump. The pump must not be used to support the pipelines.
All pipe work to and from the pump must be independently supported otherwise there is a risk of distortion of the
pump components. The suction pipe or hose should be at least the diameter of the pump’s inlet port or larger
if a highly viscous product is being pumped. The suction hose must be of a reinforced, non-collapsible type.
By fitting an over-dimensioned (2 times the diameter of the pump discharge) flexible hose to the discharge,
vibrations and/or pulsation are reduced to a minimum in the system.
The hose should be 2 - 2.5 m long and can be arranged in a loop. The discharge piping should also be at least
the same diameter as the pump port. By increasing the diameter of the piping the friction losses decrease.
Before using the pump for the first time, all external screws and nuts should be checked to match the given
torque specifications – see picture. It is advised to check the fasteners after one day of operation and there-
after every two - three months.

It is recommended to use a compatible, liquid sealant on all male threads. Be sure to tighten all connections
firmly to avoid air or fluid leakage.
The AD can only pump in one direction and the fluid inlet is below the name plate.
The arrow on the name plate shows the flow direction. The air and liquid flow is in the same direction.
Thanks to the ingenious design of the air motor (FPV - Frictionless Pivoting Valve) any type of air can be
used - dry or oily, clean or dirty. Still it is recommended to install a filter/regulator combination.
