SAO, SAG CENTRAL LUBRICATION
LUBRICATION PUMP SAO, SAG
APPLICATION
Lubricating pump sets, SAO for lubricating oils, and SAG for soft-grease, are used as a
source of pressurised lubricant, oil or soft-grease, for single-line central lubrication.
Lubricating system circuits are equipped with SKIB and SKIG series single-line metering
valves with SRK manifolds, or with SMIB and SMIG series single-line metering valves
assembled directly to the lubricated point.
Lubricating pumps with built-in control timer are usually used for cyclic, regular lubrication of
a variety of machines and equipment, e.g. textile, food-making, wood-making, shoe-making,
plastic-making, printing, paper-making, wrapping, etc.
SAO and SAG lubricating pumps are available in various execution (see tab.) with lubricant
tank volumes of 3 and 6 litres. The tanks are made of plastic. The nominal flow rate is 200
cm3/min. with maximum working pressure of 24 bar. Electric motors are normally 230V and
115V single phase. For other voltages, consult supplier.
DESCRIPTION
The lubricating pump set includes oil tank and cover. The oil tank is attached to the cover
with 6 bolts and sealed with a flat paper gasket. All parts of the lubricating pump set are
located on the cover. These are: electric motor, clutch, gear pump, suction strainer, outlet
with connecting pipe union, distributor, electric level indicator and the filler with a strainer and
a cap. The control timer and the electric motor are located under a plastic casing which is
securely attached to the cover of the lubricating set. The casing is made from two parts, from
which the upper part is detachable, enabling access to, and adjustment of, the control timer
unit. In the lower part of the casing a push button is installed for a manual start of
intermediate lubrication and 3 indicators. Individual indicators are: green light - voltage
applied, yellow light - set is in operation, red light – low oil level or, if applicable, an alarm of
the pressure switch.
OPERATION
After starting the lubricating pump set, the gear pump, driven by the electric motor, delivers
lubricant into the distributor. The distributor’s working piston is simultaneously moved into its
working position. The passage for the delivered lubrication into the lubricating circuit is thus
opened and all installed dosing devices make their stroke and deliver doses of oil into the
lubricated points. The pressure switch, which is built into the pump, is activated when the
pressure in the lubricating circuit reaches the switching pressure value. At that moment the
electric motor is switched off by an electric signal and the working piston of the distributor
returns to its zero position. With this movement the passage of the lubricant into the
lubricating circuit is closed and through the relief valve pressure decrease occurs in the
lubricating circuit. After pressure relief in the lubricating circuit, the dosing device pistons
return to their starting positions and the lubricating cycle can be repeated. Another purpose
of the pressure switch built into the pump is to control the pressure and a signal is given to
the control timer, to which it is internally connected. With a lubricating pump set with an
external pressure switch located at the end of the of the lubricating circuit, the working cycle
is entirely identical. A requirement for this is that the connection of the pressure switch to the
control timer is correct. One or several of the above-described working cycles can be in
progress during the pump operation period. It is possible to set an operation period and
pause period, during which the lubricating pump is put out of operation, on the control timer.
The control timer is not equipped with a ROM memory, therefore if the power supply is
interrupted, the set pause period will be cleared.

SERVICE AND MAINTENANCE
The SAO and SAG lubricating pump sets are installed in a horizontal position and are
attached to the machine or equipment wall. 2 x 6.5 mm diameter anchoring holes are
prepared for pump attachment.
After pump installation and connection of the outlet to the piping of the lubricating circuit the
oil tank is filled up with the specified lubricant. The outlet is designed for connection to TR 6,
outlet for connection to TR 8 or other required diameters must be specified in the order.
For SAO and SAG pumps equipped with the time control it is possible to set operation period
and pause period within a wide range. This is set before the pump's connection to the power
supply. The setting is made by selection of individual switch combinations on three change-
over relays. The operation period in seconds is selected on the relay identified as DS 2. The
basic range of pause period values in minutes (3 value series) or in hours (1 value series) is
selected on relay DS 3. Selection of the exact pause period, from the range (value series)
defined on relay DS 3, is consequently made on relay DS 1. For lubricating circuits with a
very long pause period, it is possible to set an automatic mode for intermediate lubrication. In
this mode an additional lubricating cycle is made during the pause period, during which the
pressure switch and lubricant level in the tank are checked. Automatic intermediate
lubrication mode is set by switching over the J 1 bridge. If the pump is equipped with a
control timer, internal or external, then it is activated by switching over the J 2 bridge.
The power supply for the control timer is made according to the valid regulations for electric
equipment. With the SAO 3P2 (SAG 3P2) it is first necessary to make the correct connection
of the external pressure switch to the control timer. If the pressure switch is not connected
then at the end of the first operation period a pressure alarm is signalled and the pump is
automatically put out of operation and blocked. The SAO 3P4 (SAG 3P4) pump is also
equipped with a pressure check, i.e. if the lubricating cycle is not finished during the
operation period (by a signal from the pressure switch) the pressure alarm is started (flashing
red light). With these pump variants, the manual push button for intermediate lubrication can
be used at any time during the pause period. One or more lubricating cycles is started with
this push button according to the set operation period. Subsequently the automatic clearing
of the set pause period is automatically cleared.
It is always necessary to use the push button for intermediate lubrication after refilling the
tank due to low lubricant level, where the low level alarm (lighting red indicator) has been lit
or in the case of a lubricating cycle repair after a pressure switch alarm (red light reset).
For correct functioning of the lubricating pump the lubricating circuit needs to be perfectly
bled, it is further necessary to the keep the piping clean, i.e. before pipework assembly to
remove burrs and other mechanical impurities.
Except for regular lubrication filling and suction strainer cleaning, approximately twice a year,
the pump does not require any other attention or maintenance.
