The FlexxPump 250/400 DLS is designed as an extremely compact double piston
pump for autonomous operation with grease as the lubricant. The pistons run force-
controlled and counter-rotating. The FlexxPump 250/400 DLS is available as a version
with one, two, three or four lubricant outlets, see Chapter 5. The outlets are secured by
an integrated non-return valve. Approx. 0.16 cm³ of lubricant is pumped during each
dispensing operation; multiple dispensers can be set one after the other.
The present FlexxPump4 as D version has to be integrated into an external
control (e.g. PLC). The FlexxPump 250/400 DLS has an electrical interface with
which you can control and command the FlexxPump 250/400 DLS. Furthermore,
the FlexxPump 250/400 DLS enables remote monitoring by output signals in
order to be able to query the status and possible error messages (e.g. empty
cartridge). By means of various input signals processed by the microelectronics, the
FlexxPump 250/400 DLS is controlled to supply the lubrication point with the ideal
amount of lubricant.

With the FlexxPump 411 DLS or FlexxPump 211 DLS, the theoretical two outlets of
the built-in one pump unit are combined internally. The outlet is supplied with 0.15cm³
lubricant per stroke.
5. Variants
The FlexxPump 250/400 DLS is designed as a compact central lubrication unit for
supplying one or more lubrication points. Depending on the specic application, the
FlexxPump 250/400 DLS can also reliably and cleanly supply a limited number of
lubrication points with lubricant. In this case, parts of the system accessories from
the manufacturer (e.g. splitters, progressive distributors or lubrication gears) can be
connected to the FlexxPump 250/400 DLS in order to extend the number of lubrication
points beyond the number of outlets. The FlexxPump 250/400 DLS is available as a
variant with one or as a variant with two pump bodies. The outlets of pump body (PB)
1 are marked on the housing with 1.1 and 1.2, the outlets of pump body 2 with 2.1 and
2.2.

5.4 FlexxPump 423 DLS/ FlexxPump 223 DLS
In the FlexxPump 423 DLS or FlexxPump 223 DLS, the theoretical two outlets of the
rst pump body are internally combined into one outlet 1.1. One outlet is supplied with
0.15 cm³ lubricant per stroke. The outlets are supplied with lubricant one after the other.
The FlexxPump 423 DLS or FlexxPump 223 DLS allows you to set dosing volume
differences from outlet 1.1 to outlets 2.1 and 2.2 by controlling the two pump bodies
individually. An explanation of the different control signals can be found in chapter 8.2.
If the two pump units are controlled equally, outlet 1.1 is supplied with twice the
amount of lubricant of outlets 2.1 or 2.2, due to the internal combination of the outlets of
the rst pump unit.
