This is an extremely well made siphon pump at a most reasonable price.  

No studio, either conventional, or equipped with the Z*ACRYL ETCHING SYSTEM should be without it.  It is designed for transporting any non-combustible low viscosity liquids such as nitric acid or Z*ACRYL COPPER ETCHANT.  

Operating the pump is quite simple.  A 22" length of the heavy gauge tubing is attached to the bottom "intake" coupling and a 40-45" length to the the upper "outflow" coupling.  The intake tube is placed at the bottom of the liquid to be moved and the outgoing tube is fed into the receptacle receiving the liquid.  Pump the handle a couple times to prime the pump and then pull the handle fully out.  To stop the flow at any time, simply depress the handle. 

The pump is offered with the other Z*Acryl products because it is ideal for emptying the Vertical Etching Tank of Ferric Chloride Copper Etchant.  

A word of caution, however:
Ferric chloride is highly corrosive to metal surfaces, and though it is not absorbed through the skin, it is an eye irritant and very harmful if ingested--so care must be exercised whenever handling it.  It also stains clothing quite permanently.  

After using the pump to move liquids, some of the liquid remains in the pump and hoses until it is flushed out.  Hence, it would be easy to splash some liquid around if one is not careful. With water this is not such a big deal.  With ferric chloride, or worse, nitric acid, it becomes quite a concern.  Flushing out the pump is as easy as filling the receptacle that has just been emptied with clean water and pumping it into a sink.
