Those pictures have me really stumped.
Does the pump cover actually have the Swiftech logo on it?
Back in 2005/2006 Laing issued a statement about FAKE DDC pumps made in china as knock offs. These knockoffs would not hold up to the long life like the Laing DDC pumps are capable of. Also, what is know of the fake DDC pumps is that they actually have less flow. Fake 330 l/hr vs Real Laing 380 l/hr. The Fake impeller is a clone of the vertical eheim 1046, but made out of cheaper materials.
Seems that your pump is a china knock off and fake of the real Laing DDC.
