23.570 - Plankton pump for 150 m depth:

Application:
A plankton pump pumps up seawater via a waterpipe through a small net with a mesh size depending on the intended research object. On request, the nets are available in other mesh sizes. The standard pump is delivered with 60 µm net (other mesh sizes on request). Plankton is collected in the recipient below; a flow meter can be integrated as part of the pump (optional).

Usefulness of a plankton pump:
• Research on the distribution of plankton
• The use of a plankton pump is very advantageous for sampling plankton in shallow water (compared to the use of plankton nets)
• A plankton pump can be deployed at a specific location
• Delivers reliable measurements of the filtered volume

Capacity:
Capacity up to 26.000 L/hour (app. 433 L/min. at 0 m water column).

Max. depth:
Max. depth: 150 m.

Deployment:
Use a separate steel wire for the deployment; the cable for the power supply cannot hold the weight of the pump.
