Peristatic (Peristaltic) Pump

Peristatic (Peristaltic) Pump

Peristatic (Peristaltic) Pump

(OP)
I am looking for a very small peristatic (Peristaltic)head to do the following job:
In 8 hours, at ambient T°, 200 to 400 ml of water has to go from one reservoir tank to a chamber where this water will evaporate.
The approximate (huge ) height the water has to climb is 5 cm
A close loop system with sensors in the upper chamber and a stepper motor will guarantee a constant fill of the chamber
This is not a real big deal, but considering that it is going to be a cost sensitive product, I am looking for low cost heads, if those heads are not to be found we will probably build our own but that is not the initial target.
So, if anyone knows a manufacturer of such heads, please let me know....
Many thanks in advance
HS
P.S.
While reviewing all the posts in this forum, my application sounds a bit tiny but it's still a pump .




RE: Peristatic (Peristaltic) Pump

Masterflex C/L pumps have such a head:  the pump is from Cole-Palmer

This is the link for the model that'll fit your needs, I think -- it's the whole pump, though

The manufacturer is Barnant -- I think they may work with you to provide only the head assembly (but I do not know the cost -- these are usually pretty high quality pumps).. their link is:
