measuring out pump

This barrel pump very often will be used to transport coagulants and flocculants, but there are a lot of other applications, where this kind of pump is very usefull. This measuring out pump is also available in a special sealed version. In this case you can use it to transport acidic or alcaline solutions.

low noice

function:

This pump is a self sucking, pneumatic activated piston measuring out pump. The interaction will be realised from the the air piston to the liquide piston, inside of the sucking tube. The pump strokes will be realised by a battery powered electronic control and a 3/2 ways Piezo valve in connection to a pneumatic motor.
