Turbomolecular pump + DRSSTC stuff
omegalabs, Mon Jul 18 2016, 07:13PMWeird combination, but I want to sell my unused equipment.
Pump:
Pfeiffer TPH 055 turbomolecular pump for sale. It was bought from ebay many years ago, and it was refurbished by a local professional http://bandtservice.hu/en/ and it's in perfectly working condition. I built a controller for the pump from the plans I found in the fusor forums many years ago (I can't find the exact link or the developer of the circuit right now). The outside of the pump have some dents but it doesn't affect the operation or connection. Note that there is no connector to the electrical feedthrough, the connectros are soldered to the wires right now. If needed, I can attach the PCB and the circuit plan of the controller (made with Eagle).
The pump has been in my storage for years but I decided to sell it as I don't know if I'll ever use it. I'll ship worldwide. Shipping location: Hungary.
Price: SOLD
DRSSTC:
I have a few things left of my big DRSSTC project I would like to sell.
1. Easternvoltage's flexibrute controller. I built it and tested it years ago but it never saw any mosfet or IGBT on its output. In a metal box. I ordered the 229$ version
2. Easternvoltage's modulator/interrupter. Same, tested and built. It has a fiber optic output + 2 fiber optic cable too. 184$ version
3. CM600HA-24H H-bridge plus sink. Tested on low power, they are in working condition.
I don't really want to sell them for pennies, but I really need money.
Controller 150$
Modulator 100$
IGBT's 210$
DRSSTC stuff together: 410$ (+ current transformer and GDT transformer as a gift) +shipping.

Is the pump in a working condition then? if so, I will gladly take it wih controller and all related info.
Please PM me the price + shippin to the uk (BH189NB)
EDIT:
I do have some concerns about the lack of a splinter shield, was it covered during storage? a screw in there or a bit of metal on the magnetic bearing would make it all a waste.

Yes, the turbo pump was refurbished, cleaned and tested by a professional and it works. I couldn't test myself as I don't have a whole vacuum system and any measurement devices. But it spins if I use the controller (tested only on very slow speeds).
I bought this pump used already and never used it. I have no idea what caused that dent, all of the pumps had some scratches and dents which that seller sold. After it was refurbished I placed it in a box and never used it, so there should be no problems.
