Features The SP 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 feed pump for low flow reactors, like Nitratereductors, Calciumreactors or Phosphate Filters.

If the pump is operated continously the hose should be changed every 3 – 4 months. We recommend using only 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.
