From my experience and in talking with others, they are usually very responsive to email and phone EXCEPT when they get very busy with orders. Then they drop the communication part and push instead on the orders-pending part. The owner is a very nice guy. He took time, for example, to talk with a friend of mine for a half hour long distance and at his own expense when my buddy was having difficulty with his new pump.
One factor may be that they are shipping what looks to be a potentially dangerous object to the unpracticed eye into a politically sensitive area. Plan on delays until somebody gets around to actually inspecting the pump before forwarding it on to you.
