AUF 300/AZX 1300
The AUF 300/AZX 1300 series pump is a high capacity adaptation of the AUF 200/1200, the pump body having been redesigned to incorporate a flow-smoothing unit and an air bottle.
The flow-smoothing unit consists of a diaphragm and housing situated above the delivery chamber and outlet passage. Fuel pressure pulsations are damped by the air contained in the housing, resulting in a reduction of flow pressure variations and an increase in output for a given rate of operation.
A large compartment formed in the inlet side of the pump acts as an air cushion and smoothes the pressure pulsations of the incoming fuel; it also prevents high negative pressure being created in the pump body.
Special features:
The features are similar to those of the AUF 200/AZX 1200 type, plus:
6) High output
7) Flow-smoothing on inlet and outlet
