Vertical Turbine Pumps. Use API Std 610 vertical
turbine pumps to pump from underground tanks. Do not use
horizontal transfer pumps in a pit alongside the underground
Rotary Pumps. Use sliding vane positive
applications such as stripping pipelines or similar service
where the pump may frequently lose its prime. For these
discharge side of the pumps. Note: These are considered
valve to modulate the pump output voids the pump warranty. A
variable speed motor can be used on positive displacement
pumps to gradually bring the pump to normal operating speed.
Drivers. Drive permanently installed pumps by an
electric motor which is properly classified in accordance with
NFPA 70. Drivers should be sized to be non-overloading at any
point on the curve.
Materials of Construction. For aviation turbine
fuels, require cast steel or nodular iron casings and
stainless steel impellers and trim.
Installation. Mount permanently installed pumps on
substantial foundations of reinforced concrete, designed in
accordance with Hydraulic Institute Standards. Provide drain
piping for pump and motor base, pump seal leakage, and vent
valve. When the pump is in a pump house or pump shelter,
connect drains to an oil-water separator or waste tank with
piping which includes a vertical liquid trap.
Materials of Construction. Require all valves in
steel bodies and do not allow zinc, zinc-coated, copper, or
copper bearing materials in contact with the fuel. Allow only
corrosion resistant valves such as aluminum or stainless steel
for aviation turbine fueling systems between the operating
tank outlet and the last fuel discharge point, the return
lines, circulating lines, or filter/separators. Electroplated
nickel is permitted for double-block and bleed valves and on
nodular iron hydraulically operated diaphragm control valves
