Plankton pump for vertical pull; the pump itself is constructed of AISI 316 stainless steel, and has a capacity of 13500 L per hour, the plankton pump is used to pump various size of plankton for collecting and taking samples. As standard, model plankton pump comes with a 60 µm mesh size (micro plankton), this however can be changed on request. A new net bag and a collecting bottle can be bought later on. The system is equipped with a quick change system for the collecting bottles, which enables the user to run many samples without much delay.

The pump can be operated in 2 ways:

• Programmable sampling: 
The water sampling can be programmed for various time and intervals, max. 24 times. Requires the time lapsed trigger etc., and it is programmable for any value between 1 min. and 545 hours. The standard battery capacity supports a maximum deployment up to 12 months in total, but only valid for sequential pumping, not for continuously use. Individually settings can be set for each sample. Triggering by pressure can be offered upon request.  
Needs for complete programmable sampling system: 
- Plankton pump
- Battery cylinder (6000 m depth)
- Battery charger
- Time lapsed trigger (USB interface)
- Cable
- Plug for switching on the timer

• Non-programmable sampling: 
When the pump is outside the bulwarks, ready for deployment, simply connect the power supply and the pump will start. The pump must be covered by water within short time (the pump must not be operated without water for more than 60 secs.). In this way you will pump all the way down to the desired depth; i.e. you will get samples from the entire water column.
Needs for complete programmable non sampling system: 
- Plankton pump
- Battery cylinder (6000 m depth)
- Battery charger
- Cable from battery box to motor
