Description of operation
Pump operation
Drive
• The pump housing consists of the follow-
ing components: gear motor, final gear
drive, three pumping elements connected
together by internal passages and vent
valve. Pump can be configured with inter-
nal pressure transducer.
• The gear motor shaft is connected to the
final stage gear drive.The final gear has
incorporated eccentric and cam to drive
the pumping elements and to control the
internal vent valve (†fig. 3).
• Vent valve is a two way normally closed
spring biased valve.
• Pressure transducer is adjustable.
Factory setting is 1,450 psi (80 bar). Pres-
sure setting of the pressure transducer
can be adjusted from 600 to 1,200 psi (41
to 82 bar) in 100 psi (6,9 bar) increments.

Lube cycle/pressurization
• The motor turns the cam (7) clockwise to
start lubrication cycle. As soon as pump
starts to operate, the display rotating seg-
ment is turning clockwise also († fig. 17,
page 19). Maximum time to build the pre-
set pressure is 12 minutes.
If pump does not build preset pressure,
fault signal E1 or E2 will appear on the
display.
• Vent valve (1) is normally closed and stays
closed during lubrication cycle, preventing
lubricant flow back to the reservoir
(†fig. 3).
• The output of three pump elements (4)
(† fig. 2) is combined by internal
passages.
• The eccentric drives the pump elements
to pump the lubricant from the reservoir
and build the line pressure.
• The cam (7) will keep the vent valve (1)
closed.
• Supply line can be connected to any one of
the pump element outlets.The remaining
two pump elements outlets should be
plugged.

Pump element
operation
The pump element († fig. 10 and 11) is a
single stroke spring biased pump. Motor
drives the eccentric (1). Eccentric is in
constant contact with the plunger (2).
Compression spring (3) is pushing
plunger (2) to open lubricant passage to cre-
ate vacuum to prime the pump with
lubricant from the reservoir. Check valve (4)
is closed to isolate the supply lines of the
system.
Eccentric (1) is pushing the plunger (2)
in opposite direction to pump lubricant,
developing the operating pressure. Check
valve (4) is open to pass the lubricant to sup-
ply lines.
The body of the pump element has a
lateral outlet (5) († fig. 9) for lubricant cross
porting to the internal material
passages to combine the outlet of all three
pump elements.
Any one of the three elements can be
used as a pump outlet. The remaining two
elements should be closed with plug (A)
(† fig. 9).
Pressure control/hold
time/vent cycle
Pump with internal pressure
transducer
Use only pump elements designed for
operation in the P653S pump.
Internal pressure transducer is factory set
to close at 1450 psi (80 bar). The pressure
transducer can be adjusted from 600 to
1300 psi (41 to 82 bar) in 100 psi (6.9 bar)
increments. Internal pressure transducer is
factory set to close.
After pump starts a lubrication cycle,
motor stops when pressure at pump reaches
preset pressure. Pump will go through two
holding periods, H1, H2 and H3.
Holding time (H1)
Internal pressure transducer must stay
closed for 15 consecutive seconds before
going to H2. If internal pressure transducer
opens during the 15 seconds, pump will
restart and run until internal pressure
transducer closes.
Holding time (H2) – will last for 30
seconds
• At the end of 30 seconds, if the internal
pressure transducer is closed, the pump
will begin a vent cycle.
• If at the end of the 30 seconds the internal
pressure transducer is open, the pump
will restart and run until the internal pres-
sure transducer closes. When it closes a
vent cycle will take place.
• If at the end of 30 seconds the internal
pressure transducer is closed, but during
the H1 hold time the internal pressure
transducer did open, the pump will restart
and pump for 2 seconds before a vent
cycle begins.
Possible Faults
• E1 Fault – A failure to build pressure at the
pump within the allotted 12 minutes of
pumping time.
• E3 Fault – A failure to vent at the pump.
The internal pressure transducer has
10 seconds to open when the motor
reverses to locate the vent position.

Holding time (H1)
• Internal pressure transducer must stay
closed for 15 consecutive seconds before
going to H2. If internal pressure transduc-
er opens during the 15 seconds, pump
will restart and run until internal pressure
transducer closes.
Holding time (H2) – will last for
30 seconds
• At the end of H2, if the internal pressure
transducer is closed and the external
pressure transducer is closed, pump will
begin a vent cycle. At the end of H2, if the
internal pressure transducer is open or
both the internal and external pressure
transducers are open an H3 will appear
on the display. Pump will turn on again
and pump until the internal pressure
transducer is closed. When both the inter-
nal and external pressure transducers are
closed a vent cycle will take place. If at the
end of H2 the internal pressure transduc-
er is closed but the external pressure
transducer is open, the pump will turn on
for 2 seconds and then stop and wait until
the external pressure transducer closes.
An H3 will appear on the display. When
both the internal and external pressure
transducers are closed a vent cycle will
take place.

Venting cycle
• After the pump completes the preset hold
time and the pump maintains the speci-
fied pressure, the controller will initiate a
vent cycle. The vent cycle will last for ten
seconds.
• The motor will turn counterclockwise to
engage and open the internal vent valve.
The display’s rotating segment is turning
counter clockwise.
• The motor will stop in a position to hold
the vent valve open. “Hr” will be displayed
for the remainder of the 10 seconds.
Filling reservoir with oil
Remove top cover and pour oil into strainer
and install cover on reservoir. Tighten cover.
Initiate the lubrication cycle to start the
motor.
Stirring paddle
The stirring paddle (1) († fig. 12) is
attached to the motor and rotates during the
lubrication cycle. The paddle is working oil in
the reservoir.
Low–level control
The pump model P653S is equipped with a
low–level oil control as a standard feature.
The low level control consists of an
electromagnetic reed switch and a magnetic
float at the bottom of housing. The switch is
sealed and does not have any contact with
oil.
As soon as the float reaches the preset
position at the bottom of the reservoir,
a magnetic field will open the switch to indi-
cate the low–level of the oil. The control pan-
el display “LL” will be on.
The electromagnetic reed switch is closed
when oil in the housing.
Always refill the pump to the maximum of
the reservoir capacity. The “LL” display
should be “off” as soon as pump is refilled.
