4 / INSTALLATION
4.1 - SYSTEM DESIGN AND INSTALLATION
For the air connections, use an oversize air line of minimum 10 mm diameter.
When a pump is to be incorporated in a system, it is good practice to, as far as possible, minimise the length
of the pipes/hoses and the number of fittings (tees, unions, bends, etc.) and restrictions.
When designing the suction lines, particular care should be taken. These should be as short and straight as possible, us-
ing a minimum of fittings to optimise a good product flow to the pump. Use a reinforced, non-collapsible hose of at least
the same inner diameter as the suction port.
Always consider the following when designing a system : make sure that there is enough room provided
around the pump to allow for routine service work, i.e. to dismantle the covers to inspect or change the
diaphragms and check valves. The Liquid Flow comes with a stainless steel foot plate and rubber feet.
For security reasons it is recommended to bolt the pump to a base.
Thanks to the flap valves the pump can be mounted upside-down, sideways or on any of its 360-degree axis
(see illustration).
