vac pump or no vac pump
I believe this question is probably ones own opinion. I have used 3 different types of system two of them have no external pump (hoses) and other one does have one.
My first system that I purchased was by Liquid Resins. You have an option of using a pump or not, with a little time and getting used to your own equipment you will know when or when you really don't need a pump. Liquid Resins and other companies that use a similar injector share this concept.
*CONCEPT* is to vacuum all the air out first prior to injecting the resin which accelerates the repair pressure. After vacuum you release the air which assist the resin to go further. Repeat the process until you see no change. Then you can remove the hose and work the break with the built in probe which you can manipulate between vacuum and pressure.
My second and third system does not contain an external vacuum pump but vacuum is made by the drawing of a plunger up (kind of like a toilet plunger which is generated by a little down pressure) or I guess the industry calls it a internal pump?. I find that Delta Kit system pulls a better vacuum than the white plastic injectors. Again this is my opinion and some may correct me. I find both these system to be simplistic but the white injector requires a little more work. Don't get me wrong with these little white injectors in a hand of a good technician, you can develop some skill which you can carry to other systems that you may use in the future which can make your repair much better. The *CONCEPT* of these two repair system is not to vacuum first, but to fill the space with resin forcing the air out. (Similar to an empty soda can, you necessarily don't have to pump the air out of it to put soda in it. Also they believe that if you over vacuum you may shut or close parts of the break, again similar to a soda can when you over vacuum it will crush) Again this is my opinion but the resins does appear to fill in more quickly with these type of systems but you still have to work out getting the air out. Which to me takes a tad bit more longer than my other system.
If I were to choose one or the other and if I were on a tight budget I would get one without the external pump. This way I can keep a little more money for myself, and learn different techniques that I may of never learned if I had just a system that was just too perfect.
