INSTALLATION

Piping

All piping material must be compatible with the liq­
uid being pumped. If hose is used in suction lines,
it must be the rigid‐wall, reinforced type to prevent
collapse under suction.

Run the 8‐inch suction piping from the tank sump
to the pump inlet. The suction lines should be as
short and straight as possible to minimize friction
loss.

A suction strainer was not furnished with this pump
since it is not designed to handle liquids containing
solids. However, to protect the pump from acciden­
tal damage a commercially available 80 mesh
screen should be installed in the suction line. Make
certain that the total open area of the screen is at
least three or four times the cross section of the
suction line to ensure an adequate supply of liquid
to the pump.

Damage to the pump resulting from debris
in the suction line will not be covered by the
pump warranty.

Before connecting the suction and dis­
charge piping, carefully check the storage
tank and piping for construction debris
such as nuts, bolts, wire, weld slag, and
other foreign material. Install a commer­
cially available 80 mesh screen in the suc­

tion line to prevent debris from entering the
pump.

The pump discharge is a 6‐inch petroleum flange.
The discharge should be mounted vertically just
below the top of the chassis frame. It can easily be
piped to the filter inlet, discharge manifold, valves,
etc..

To avoid wracking, flexible connections or bellows
must be installed in the pump suction and dis­
charge.

Do not tighten connecting flanges unless they are
properly aligned. Never pull a pipe into place by
tightening the flange bolts.

Valves

Gorman‐Rupp manufactures several sizes of flow‐
diverting (FDF) valves for use in truck‐mounted
pumping applications. The valves are designed to
reverse the flow of liquid with only the turn of a han­
dle. This allows the same pump to fill or dispense
from the tank.

The FDF valve is designed for directing
flow only. It will not serve as a positive shut­
off or throttling valve.

See Figures 8 and 9 illustrating the installation di­
mensions and theory of operation for a typical FDF
valve. Consult the factory for further assistance or
other sizes.
