bon mes pas de facture

Brza isporuka, pumpa je isprobana i radi dobro. Plasticni cep bi trebao biti metalni!

Wonderful product . only issue it was delivered with full of oil and it was spilled every where.

Used for HR freeze Dryer . NO MORE LOW VACUME ERRORS. Needed to Fabricate a check valve. Needed to drill and tap for drain valve. Needed to use a motor starter Relay "00" size for power. & End Bell cover needed Shims, The fan was Interfering. Went with two pumps this one and original HR pump. Also needed one more suction line and a "JIC" "T" for plumbing. Would I do it again? Yes

Erittäin tehokas ja hyvän oloinen pumppu. Todella nopella toimituksella voin suositella muillekkin.

Estoy empezando a realizar pruebas con una ventosa en un control numérico y de momento todo perfecto se comporta muy bien. Quisiera saber si se puede reemplazar la boquilla de ingreso de aire que tiene dos entradas y una especie de válvula antiretorno en el fondo, por un espigón recto de mayor paso, para acoplar una manguera que conecto a un calderin que hace de pulmón de reserva. Sin más les saludo cordialmente.

Very pleased it’s a cheap pump price wise quality looks very well. I haven’t used it much but I am very happy with it.

Very nice price for a vacuum pump who gets the job done. I would buy it again every year of i need one

At first I was pretty disappointed with this vacuum pump. It struggled to achieve the same vacuum as my old 1/3hp pump. But one of the previous reviews on this page pointed me in the right direction: the outlet filter is much too restrictive. Removing it (the cap that houses it can be opened by undoing one Philips screw) fixed everything, and now I can achieve 50-100 micron vacuum instead of the 400 microns that my 1/3hp pump was limited to. I've observed no ill effects from running without any filter, but I'm sure it's a warranty killer.

La macchina và in protezione con temperature ambiente oltre i 35 gradi.. peccato perché ho perso un sacco di tempo per fare un vuoto..
