5.2.1.3 Super high speed delivery rate (Qmax 130 L/min)
For the super high speed delivery rate the pumping unit is connected to two meters feeding one
hose and nozzle at a maximum flow rate of 130 litres per minute. This configuration is suitable
for use with diesel only. The minimum delivery is 5 litres.
5.2.2 Sealing (Figure 28)
The meter is sealed by means of a wire, which passes through tabs and cast bosses on the sheet
metal and cast components of the pump meter and pulser.
I. Pulser; A seal wire passes through two sets of aligned holes in the body and lid of the
pulser. The holes are in diagonally opposite corners of unit and the seal is made close to one of
the corners.
II & III. Meter; The wire first threads through the lead seal then to a hole in the bell
housing flange of the meter on to a tab with hole on the pulser gear retaining plate, round to the
back plate of the meter through aligned holes in the meter body and back plate. The wire now
passes through two similarly positioned holes in two corners of the bottom plate then returns
via another hole in the back plate to bell housing and on to a second tab/hole in the pulser gear
plate, and finally to the lead seal.
IV. Calibration wheels, and meter to dispenser; A wire is passed from the seal through a
hole in the calibration cover then the cover securing screw to a hole in the pumping unit top
and back to the seal.
V. Blanked pump port (where only one meter is installed) A wire is passed through holes in
the nut end of the two securing bolts preventing their removal or rotation. The seal is made
between the two bolts.
All seal wires are drawn taut through all the holes prior to sealing
5.2.3 Authorised Alternatives
Having the PAS V3 combined pump and air separator unit described but having a modified
vortex valve and outlet non-return valve. This is identified by a data plate that references
OIML certificate number “OIML R117-95-NL-01.04”.
5.3 Alternative Tokheim combined pump and air separator unit EPZ (Figure
29)
Having the dispensers as described in the Certificate but replacing the existing pump and air
separator unit with the Tokheim EPZ pump and air separator unit. This can be configured with
different combinations of meters and nozzles to give different maximum flow rates (Qmax)
