The box bears the detailed pump specifications and its brief description:

Besides the actual device, you also get an instructions sheet and a set of screws with washers:

Laing DDC has been in the market for a long time, for over 4 years now, but it has proven so efficient among computer enthusiasts that no one has any intention to discontinue it or replace with a new model. There are quite a few modifications of Laing DDC in the market today.

The pump and expansion tank (mostly the tank, of course) look very attractive:

Clear acrylic casing of the tank is installed right onto the pump and fastened to it with four screws:

You can even see the pump blades through clear acrylic. There is a small sticker with the marking and electrical characteristics on one side of the pump:

According to the specifications, Laing DDC performance is about 420 l/h, maximum head is 3.7 m and maximum operational temperature – 60 °C.

There is a threaded lid on top of the tank with a sealing rubber ring and two G1/4” holes for the fittings on the side:

The pump is powered from a 12 V Molex connector is consumes no more than 11 W. There is another cable for monitoring the pump operation that should be connected to a three-pin mainboard connector:

During the tests Laing DDC was installed onto the radiator retention plate from Thermaltake PW880i, i.e. onto the same exact spot where the default Thermaltake pump used to be:

However, this is not the only way you can install Laing DDC, because it comes with four anti-vibration screws that allow fastening the pump and the expansion tank inside the HDD chassis. Very convenient and practical.
