Crossporting of the SSV divider blocks
Single Output
A single output is the lubricant quantity fed to the lube point
by a piston per stroke and outlet port. It amounts to ap-
proximately 0.2 cm³, see outlet 6, fig. 1.
Double or Multiple Outputs
Outputs can be increased by simply plugging the unused
outlet ports with closure plugs (fig. 2, provided in the ac-
cessory kit).
Lubricant from a plugged outlet is redirected to the next
outlet on the same side of the SSV divider block in de-
scending numerical order (see fig.1).
Example, see fig. 1:
By closing
- of outlet 4, outlet 2 receives the double quantity.
- of outlets 5 and 3, outlet 1 receives the triple amount of
lubricant. The connecting conduit from outlet line 1 to
outlet line 2 and to the return line (R) is closed by
clamping rings (A) of the check valve.
Unused lubricant can be internally fed back to the reser-
voir, see paragraph ‘’direct internal feed back feature”.

Direct (internal) feedback feature
All pumps with back- mounted SSV divider block have
the capability to feed back unused lubricant internally from
closed outlets directly to the reservoir (see R fig. 4, 5).
This procedure will start automatically, if outlet port 2 is
plugged with a closure plug. All pumps have capability to
feed back the lubricant directly to the reservoir from even
and odd outlets via the channel from outlet 1 to outlet 2 .
Start from the smallest outlet number when closing the
outlets, for instance 2, 4, 6 on even side or 1, 3, 5 on odd
side plus outlet 2. In fig. 4 the quantities of outlets 1, 2 and
4 (3xR) are fed back to the reservoir.
The remaining outlets are to be used for the connection to
the lube point or for increasing the lubricant quantity (dou-
ble or triple), see fig.1.
1013A94
CAUTION!
To change the outlet 2 for bearing lubri-
cation, replace closure plug with check
valve (Fig. 3), then never close outlet
1, see fig. 1.
6001a02
NOTE
To feed back unneeded lubricant quanti-
ties from bottom- mounted divider
blocks to the reservoir, connect un-
needed outlet via the feedline to plug 5
(fig. 17) for external return line.

Fig. 20 QLS 301 with bottom position of the SSV divider block
The QLS 301 is a complete compact lubrication system
for a maximum of 18 lubrication points per cycle.
The pump has three basic configurations:
- SSV divider block mounted on the back (see Fig. 19)
- SSV divider block mounted on the bottom (see Fig. 20)
- Pump without the SSV divider block attached respec-
tively with external divider block KNQLS (see fig. 21)
The pump with the SSV divider block mounted on the
bottom has the capability of using steel tubing as lubrica-
tion lines if necessary.
Standard lubrication lines are high-pressure plastic hoses
included in the pump installation kit for pumps with the
SSV divider block attached.
6001a02
NOTE
The function of the pump is independent
of the SSV divider block's mounting posi-
tion.
A signal from the pump timer starts the electric motor and
the pumping element starts pumping the lubricant to the
SSV divider block.
When all lubrication points have received lubricant, an
internal proximity switch 1 Fig. 19 (initiator) turns the mo-
tor off, completing one lubrication cycle.
If the pump does not complete the cycle within 15 minutes
of operation, the alarm message ”Er” will be displayed as
a flashing light in the keypad window, see fig. 26.
