A very reliable
dosing pump ideally suited to dosing Dryden Aqua
flocculents APF. Our flocculent only needs to be used at extremely low
concentrations. In a typical swimming pool type application the dose rate
will be around 10 to 20ml per hour for every 100 cubic meters of water
pumped through the treatment system. Dosing such a small volume of
water against pressure of up to 10 bar can be a problem. After
extensive testing Dryden Aqua recommend the type D209-04 pump.
Instead of having to convert the required litre capacity per hour into the
corresponding stroke frequency (strokes per minute) of the pump, all you now
need to do with DDI is enter the litres per hour. You no longer need either
knowledge of equations or a pocket calculator. The stroke adjustment button
is thus consigned to history.
The pump can, be adapted quickly and easily to the user’s own specific
process requirements. The calibration process is also particularly
straightforward. The integrated microelectronics calculate the correction
factor that is needed and within a few moments the pump is ready for
high-precision operation. Even inexperienced operators require only a few
minutes to learn the most important steps.
