1. Features
The SP 1500/3000 is a peristaltic pump in which liquid is transported by repeatedly kneading the
pump hose. It can be used wherever small amounts of liquid have to be pumped.
In the aquarium, the pump can be used for two purposes:
-
as feeding pump for low flow reactors, like Nitratereductors, Calciumreactors or Phosphate
filters
-
as dosing pump for fertilizers in fresh water aquaria and for trace elements, calcium and
bicarbonates in salt water aquaria.
The dosing pump is supplied with a long lasting synchronous motor and the pump hose is made of
Santoprene®, a specially developed material resistant to many chemicals and with a very long life
– normally in excess of 3 million compressions.
Important note:
The pump must be operated at the correct voltage (see type label).

3. Connections
The pump is connected with aquarium air hose (6 mm), ¼". However, it should be assured that the
hose is suitable for the chemical characteristics of the liquid being pumped.
4. Installation
The pump may only be operated in the dry, it is not designed for submersed use. It should be
securely mounted using the keyhole slots provided in a dry place.
The pump may only be operated with check valve and should always be set up in such a way that it
is placed above the water level of the storage vessel, tank or filter basin (see Fig. 1).
The outlet should always be positioned above the aquarium or sump. If the pump stops with the
drive axle in the horizontal position then the pump will not act as a check valve. The air gap
between the outlet hose and water prevents aquarium water being syphoned back into the liquid
storage tank. If small amounts of water need to be precisely dosed then a check valve should be
placed in the inlet hose of the pump. This prevents the pressure tube emptying and ensures that
the same volume is dosed during each operating cycle.
