Estimated delivery time 3 business days


Product Overview

Untested for parts or repair.

We were unable to power as we did not understand the wiring, there is ten wires. We do not know the history of the pump but we pulled the fan cover off to turn by hand and found the plastic fan had a little damage and was making contact on one side for a half turn each revolution. The cover also had a cracked corner.

We are selling AS-IS, no returns due to lack of testing and the noted observations about the fan and cover.

Item was as described, and very fast delivery!

5 stars across the board for every seller rating category, and I would buy from this seller again. And per my request, the capacitors were also very well packed for safe delivery.

Obtainium have been a very helpful seller to me.

In recent times I have had a few items go astray enroute to my address in Australia. This seller was most helpful & encouraging, regarding the onward tracking & eventual safe delivery of this item. This item's arrival in good condition was a joy to me as, it was a rare part that fitted my military comms. Well done seller. I would gladly recommend this seller to all potential buyers.
