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.
