Caterpillar feed pumps
The Caterpillar feed pump is a low-pressure fuel pump. The main objective of this device is the function of supplying fuel to a high-pressure fuel pump - the Caterpillar injection pump. Typically, a feed pump is installed on the injection pump housing or in the immediate vicinity of injection pump.
Both pumps are connected by means of fuel pipes, through which fuel is supplied from one pump to another.
The Caterpillar feed pump (low pressure fuel pump) is needed to pass fuel through the Caterpillar filters and then inject the fuel into the high-pressure fuel pump - the Caterpillar injection pump.
It is worth noting that the feed pump pumps a little more fuel than the engine needs to operate. This swap "with a margin" allows you to maintain the optimum pressure in the fuel system, avoiding increasing loads.
