▪ Static lift must not exceed 3 metres (vertical distance from the product level in the tank
to the centre of the pump unit).
▪ To absorb ground movement from settling of the tank, frost heaving of the ground or
pump island settling, a swing joint must be used in the supply line at the tank and
directly underneath the dispenser. Three additional directional changes using elbows
are permitted.
▪ Piping must hold a 3.4 Bar (50PSI) pressure test for a minimum of 10 minutes.
Refer to the footprint drawings for pump installation details.
Check Valve
A Check Valve must be installed at the tank end of the suction pipe on the top of the tank in a
serviceable location. Many clients install an extra check valve at the inlet to the pump. It is
important neither of the check valves interfere with the flow of fuel. They must be adequately
sized.
