Have we ever thought of extend life expectancy of the original parts by ourselves. As the original parts, such as pump heads, valves, inkcores, valves, can easily costs us an arm and a leg.
We can buy a new(if with enough budget), a refurbished or a compatible(if there is) one, but why not try to fix the spare part by yourself.
Take the Domino A series pump head for example, in most cases, the problem of a faulty pump head lies in the worn out gears, we could try replace the gears kit first. For the leaky Videojet inkcore and Markem Imaje electrovalve, we can take a look at the sealings.

We provide various small parts compatible to the original CIJ parts, please feel free to drop us an inquiry, better with pictures.
