POST-STARTUP TESTS
Voltage
The incoming voltage to the pump should be checked and any reading not within 10% of rated
voltage should be corrected before testing is continued. When dealing with suction pumps it is
good practice to take voltage readings while the suction pump is operating on bypass (turned on
but not dispensing product) and also while making a delivery. Any voltage drop in excess of 10%
during either of these operating states should be considered a low voltage condition. Corrective
action should be taken to insure an adequate power supply to the pump.
Tightness
After determining that the pump is operating satisfactorily and the system is fully primed, check the
pump and piping to make sure that all connections are tight.
Meter Calibration
The 580 Series Pump is adjusted for accurate measure of the specified fuel (gasoline or diesel)
within + .05 gallons at the factory. However, since the conditions of the installation can affect
pump accuracy, it is the responsibility of the installer to check the pump for accuracy and make
any needed adjustments.
Choose the flow rate at which the meter will be used most often for the zero calibration point. For
example, if the pump is being used with an automatic nozzle, calibrate with the nozzle set on the
middle or top notch position, whichever is used most frequently.
Use a certified seraphin can to conduct the test. Fill and drain the test measure to completely wet
the interior surfaces. Reset the register to zero and deliver an exact amount into the test can at
the selected flow. Read the level of the liquid in the sight glass on the scale in + cubic inches.
The calibration adjustment screw is located on the underside of the meter just behind and to the
left of the meter inlet. Using a flat-blade screwdriver, turn the adjusting screw clockwise to correct
for plus cubic inches or counterclockwise for minus cubic inches in the test measure.
Count the number of full turns and fractional turns each time for reference in judging the number
and direction of any additional turns required to calibrate the meter to exact zero.
Strainer Cleaning
Clean the strainer immediately after the pump has been installed and tested, and again after a few
hundred gallons have been delivered. Thereafter, once every six months, or as required. The
procedure for cleaning the strainer can be found in the Maintenance and Troubleshooting
section.
Belt
Since belts do stretch slightly during the first few minutes of operation, check the belt tension after
completing the operational test. See the Maintenance and Troubleshooting section for details.
RECONFIGURATION OF PUMP PULLEY FOR HAND CRANK OPERATION
Before a hand crank can be used to pump fuel, you must reconfigure the pump pulley as follows:
1. Unscrew and remove the screw (15), lock washer (14),
washer (13), and pump pulley (12).
2. Flip the pump pulley (12) around so the shorter groove at
the back is exposed at the front end.
3. Replace the pump pulley (12), washer (13), lock washer
(14), and screw (15) and tighten the screw.
4. Engage the hand crank belt (item 13 on page 6-16) to the
shorter groove.
