Installing A Red Jacket Submersible LPG Pump-Motor Unit
General
These instructions must be read fully before putting a submersible turbine pump for LPG into operation.
This LPG submersible pump is designed to pump a mixture of liquid petroleum gasses consisting of butane and
propane, used as fuel to power motor vehicles.
These instructions only relate to the installation and operation of the submersible pump and not to the dispenser,
which measures and registers the actual sales of the product.
The installation of the Red Jacket submersible LPG pumps should only be conducted in the presence of an
authorized technician.
System Description
The Red Jacket submersible LPG pump is fitted into the special developed manifold, which has to be installed into
one of the manholes of the storage tank (see below and Figure 4 for dimensions within manifold). At the bottom of
the manifold a shut-off valve is installed, which can be operated from the outside above the storage tank, so the
manifold can be closed. By closing this valve the pump can be separated from the stored fuel in the storage tank.
On the closing flange of the manifold a nitrogen connection is fitted. When nitrogen is admitted into the manifold,
the LPG liquid is pressured back into the storage tank. When the shut-off valve is closed it is possible to safely
remove or install the submersible LPG pump in a filled tank.
