Figure 13: Typical Metering Pump Installation (Standard Mounting on a Wall)
(3) The metering pump system is a fixed displacement pump. The pump shaft is driven by
a gearmotor at a specific rpm, for each specific model. This delivers a constant flow
(gph) of fuel. Change in oil viscosity and temperature have very little effect on fuel flow.
Therefore no oil pressure adjustment is needed for the metering pump system.
(4) The metering pump must be mounted as close to the tank as possible. The suction oil
line (length of oil line from the bottom of the tank up to the pump) must not exceed 8
vertical feet. Every 3 horizontal feet of suction line reduces the maximum allowable
vertical lift by 1 foot.
(5) The suction oil line must be a minimum of 8” from the bottom of the tank to reduce the
likelihood of sludge and/or water being delivered to the boiler.
(6) The metering pump system is not weatherproof. Mount the pump indoors only.
Mounting the metering pump assembly:
NOTICE:
The metering pump system comes assembled for standard mounting on a wall.
STANDARD MOUNTING:
(1) Refer to Figure 13 for a typical metering pump installation (standard mounting on a wall).
(2) Use appropriate hardware to mount the metering pump system to the wall.
(3) Keep the pump assembly as close to the tank as possible.
ALTERNATE MOUNTING:
(1) Refer to Figure 14 for an illustration of the alternate horizontal mounting.
(2) Loosen the pump head and rotate it 90
o
. The pump assembly may now be mounted in the
horizontal position as on a shelf.
