A pressure gauge located at the pump must be used
when making adjustment to insure the pressure
settings do not exceed limits specified for the
particular pump of maximum system pressure.
Make all pressure settings with pump operating
against a closed circuit, that is with the output of the
pump blocked, and then check pressure throughout
the pump flow range.
Volume Control
Adjust volume at minimum pump pressure or at pump
deadhead. The volume adjusting screw is directly
opposite the pressure adjusting screw, see parts page
item number 55. The adjusting screw has a right
hand thread, turning the screw clockwise decreases
the maximum volume, turning the screw
counterclockwise increases the maximum volume.
Pumps are set at a maximum rated volume at the
factory unless otherwise specified.
Stop adjustment of the volume screw when pressure
begins to drop. See Sales Catalog for complete
pump performance specifications.
ADJUSTMENT PROCEDURES
To adjust the maximum output volume use the
following steps:
1. Set the pump at minimum pressure.
2. Hand tighten the volume screw until it touches
pressure ring.
NOTE:
The pump should be at full flow
for this step.
3. See Pressure and Volume Adjustment Sensitivity
chart below.
4. Deadhead the pump, turn the volume screw the
proper number of turns to obtain the flow desired.
5. Return pump to flow condition and check flow rate.
If output flow is incorrect, switch pump to deadhead
and readjust.
CAUTION -
Turning the maximum volume
control in too far can force the pressure ring
over-center and destroy the pump.
