DFP1, DFP3 and DFP6 diaphragm feed pumps are primarily intended
for use with engines the fuel supply of which is below the level of the
injection pump. The range is designed mainly for oil engines although
the DFP3 double-diaphragm models may be for multi-fuel engine
application.
Whilst DFP1 feed pumps have been developed for use with BPE fuel
injection pumps, DFP3 feed pumps are intended for use with N and
NN injection pumps and DFP6 feed pumps are designed for use in
conjunction with the AA range of injection pumps.
Diaphragm feed pumps are mounted on the side of the injection pump,
thus providing an uninterrupted supply of fuel oil at constant pressure
to the injection pump inlet. In this way, pressure fluctuation is
eliminated and calibration of the injection pump becomes regularised.
Basically, the pumps consist of a diaphragm contained in a suitable
housing, and actuated by an eccentric on the injection pump cam-
shaft through a bell-crank lever.
