Well I received the second shipment of pumps today. They were packaged exactly the same way, with only a couple thin pieces of styrofoam holding the pump in position. One pump arrived with the impeller housing again popped away from the motor, and broken pieces inside the cage. The second pump arrived without any shrinkwrap, missing the 1.5" hose connector, and having the same broken piece inside as the rest, but the broken piece was not inside the box.
It seems that the standoff that is broken in all of them (sitting directly behind the motor) does not actually hold it in position while running, but I could be wrong. Between four broken up pumps, I could piece together two working units (except for the broken standoff). I went ahead and threw one in my pond to see how the motor works, and am pleased that it seems to push a lot more water than my old brand of pump (plus these are rated to use 1/3 the wattage), so it seems that the pump itself is good quality, even if they don't package them properly for shipping.
So my question to everyone - what should I do now? These are Laguna Max-flo 2900 pumps, which was given a good rating in various threads on this forum. I *could* make two usable pumps out of all this mess, or I could call the reseller up on Monday and ask what is going on with these (and I do have the time to do this still). Is the general consensus still in agreement that these are a good quality pump? Has anyone else used this particular pump, and also seen such crappy packaging? This is certainly not what I would expect from a company that ships out product via mail-order, and as I think the pumps would have a much better change of arriving intact if they simply put some packing cardboard inside the cage to prevent the pump from coming loose and destroying everything inside the cage.
I'm just not sure where to go from here, and getting frustrated with something that should be a very simple matter.
