REMOTE CONTROL
If remote control pump unit, Part No. 563376 (521-500-430) is
selected the following recommendations for pump setting should
be followed:
To determine total pump run time per hour, divide the total system
design volume (cu.in. pr hr.) by the pump delivery rate per minute
(.120 cu.in./min.).
In the example, the total design volume is .628 cu.in./hr. thus,
.628 ÷ .120 = 5.22 minutes/hour. It is recommended that one
quarter of the total design volume be supplied to the system every
15 minutes therefore, the remote control should provide 1.3 min.
(78 sec.) of "on" time every 15 minutes.
Note:
In systems where central pressure signaling is desired the
pump "on" time should not be less than .5 min. (30 sec.) per
each cycle time.
INSTALLATION
Because of the low volume capabilities of the Maxi-Flo system, it
is recommended that 1/8" O.D. (.020 wall) copper/nylon tubing
be used throughout the system, from the pump to master divider
valves, master divider valves to secondary divider valves, and
secondary divider valves to lube points.
Hose should be used only when absolutely necessary. A 3/16"
inside diameter L.V.E. (low volumetric expansion) hose is
recommended.
All divider valve assemblies should be centrally located to the lube
points they serve to provide the shortest feed lines possible.
As in any lube system all air should be removed from the Maxi-
Flo system for effective oil delivery to lube points (see Lit. No.
L30103). Installation of Graco manual reset indicators Part No. –
(509-931-000) in working outlet of divider valves is recommended
in order to facilitate system troubleshooting.
