5. Parts List Dosing Pump SP 3000
Available spare parts: Please refer to www.aqua-medic.de.
6. Control
The synchronous motor of the pump operates at a fixed speed of 20 rpm. This cannot be changed. If smaller
amounts of water are to be dosed or a smaller flow rate is required, the SP 3000 can be switched on and off for
varying periods of times. For exact dosing, a digital timer, programmable in minutes, should be used.
Important: Never use the pump together with a valve. If you want to reduce the flow rate, use a timer
(15 minutes "On", 15 minutes "Off" = ½ flow rate).
7. Maintenance
The pump hose and the motor are consumables and have to be maintained and changed regularly.
Pump hose: The pump hose has a lifetime of approx. 3 million rotations and after this usage, it needs
replacement. If the pump is operated continuously, the hose should be changed every 3 – 4 months. We
recommend only to use an original Aqua Medic spare pump hose assembly which is supplied complete with
fittings.
Grease: Before the hose is installed it has to be greased. The pump will only operate properly if the hose is
effectively greased.
Heat: During continuous operation the motor may heat up as high as 70 °C. This is normal and has no effect on
performance or the life. However, too little grease on the pump hose may cause malfunction of the motor and
overheating.
