Overview

The PMP-400 pump, offered by Koolance, is a so-called electronically commutated ball motor. Here a spherically shaped rotor assembly moves in a similarly shaped housing ? Only held by the surrounding magnets in this position. Only a ceramic ball serves as a connection, which is extremely wear-resistant due to its enormous hardness. Other moving elements were deliberately omitted. For the actual rotation of the impeller unit, a smooth magnetic field is generated, which is generated by the all-round electromagnets.

Details

In practice, this works like this: The water is supplied via the upper-central inlet, flows downwards through the central bore of the rotor unit and is there transported upwards and accelerated by the rotation along the outer side, whereupon the outlet sits accordingly. The most obvious advantage of this design is the minimal contact surface between the moving parts, which is restricted to the ceramic ball.

Thus, there is initially a minimum transmission area for vibrations, which results in a very low noise level. However, this principle can show its efficiency particularly in the case of continuous use: Increasing bearing play and thus a volume increase can not arise as a matter of principle. Also lubrication is not necessary, since the water itself provides for this. Likewise, contamination is not a problem, because if the rotor is to be blocked, it will continue to run as before.

The model presented here by Koolance PMP-400 already has an enormous delivery height of 3.7 m and therefore a high water pressure as well as a maximum delivery volume of 420 liters per hour. This data is identical to an original Laing pump of the DDC-1T model. The pump is thus already suitable for extensive cooling systems.

The Koolance PMP-400 has two plug connections for 9,5 mm (3/8 inch) diameter tubing and can be used with hoses of an appropriate internal diameter (ID). The power connection is provided with a standard 3-pin fan plug. This is also used for reading the rotational speed, which corresponds to the pump rotation. The lid can be easily removed so that the pump is fully compatible with optional DDC Bays and DDC reservoirs.

Note: Due to the high power consumption of the pump, we recommend connecting it to a suitable pump control instead of a fan connection on the mainboard.
