Dosing pumps

42.1

Peristaltic pumps

The standard PoolManager ® dosing pumps are so-called peristaltic
pumps (hose pumps). Rollers on the rotor continuously squeeze the
dosage hose, thereby providing for the dosing of maintenance
products.
The pump's dosage hose is replaceable. The pump's dosing output
can be adjusted via various hose diameters.
The following table shows the standard dosing outputs on
PoolManager ® dosing pumps.
Function
pH (pH minus / pH plus)
Cl (sodium hypochlorite)
O2 (Bayrosoft )
®
The pumps used are run with a 230 V~ power supply. PoolManager
control system periodically turns the dosing pumps on and off within a
fixed dosage cycle (typically 60s) in order to realise the dosing output
calculated. A higher dosing output will lead to longer turn-on times.

Electrical connection

Required user qualification:
ELECTRICAL SPECIALIST
The electrical connection for eco mode may only be
performed by an ELECTRICAL SPECIALIST as
defined in the chapter User qualification.
The following figure shows the internal wiring of the three dosing
outputs for disinfection, pH-, and pH+. All connections shown are run
internally as conductor paths.

order to control 230 VAC devices.
The following figure schematically shows the connection of a standard
dosing pump for 230 V~. The pump is connected to the disinfection
dosing output. For pH- and pH+, connection is correspondingly on
terminal blocks [21] and [22], respectively.
