7.4 Pump Discharge Piping for Blue Diver 1200 Only
• The discharge connection of the pump can be made
with stainless steel or rigid polypropylene parts.
• Avoid any reduction of the output pipe.
• It is advisable to use pipes with an internal diameter at
least equal to that of the delivery pipe, so as to avoid a
fall in the performance of the pump and the possibility
of clogging.
• To lower the pump, always use a stainless steel or poly
chain fixed beforehand to the hook on top of the pump.
Hose made of approved materials may be used if
proper lift cable or chain is used.
• Verify all fittings are DEF compatible.
• The bypass assembly and check valve must be
installed as shown in Fig 7.4, for the Blue Diver 1200.
The bypass assembly ensures that, when energized,
there will always be flow through the pump. Blue Diver
pumps rely on flow to cool the pump, and must never
be run dry or dead headed.
•
Never use the power cable to lift the pump.
•
Dry operation or closed valve operation of the
pump causes irreparable damage to the mechanical
seal and will cause premature failure.
• Check & Relief Assembly must be used on Blue Diver
1200. Waranty is VOID if installed without this
assembly.
