Oil Heat Terminology
- Single-stage
fuel unit: Unit with one set of gears for both suction
and pressure.
- Two-stage
fuel unit: Unit with two sets of gears, one for suction
and one for pressure.
- One-pipe
system: One line, an inlet line from tank to fuel
unit.
- Two-pipe: Two
lines, one inlet and one return line from tank to fuel unit.
- Bypass
plug: Small hex socket head pipe plug used to close
internal port and convert unit from one pipe to two pipe operation.
- Bleed: To
remove air from a system.
- Lift: Oil
drawn from a level below the pump expressed in feet of lift or inches of
mercury.
- Head
of oil: Column of oil above the fuel unit expressed in
psi or feet.
- Inlet
port: Port which receives oil from tank.
- Bypass
port: Port which discharges surplus oil back to tank in
two-pipe systems.
- Return
line port: Same as by-pass port.
- Valve
differential: Number of pound per square inch the pump
pressure must drop from operating pressure to close nozzle valve.
- Delivery:
Gallons per hour pumped from the nozzle outlet assembly of the fuel unit.
- Gear
set capacity: Total amount of oil being displaced by the
pumps gear set(s).
