It's a newer version with multiple improvements made, including better bleeding of the air thanks to a smaller OD magnet, better electronics, a connector on the pump body to prevent wires from getting damaged if pulled on too hard, and more.
the MCP50X is based on the same technology, the motor is stronger - it is a 6-pole design (as opposed to a 4-pole design on the H220/Glacer240), with more torque and higher RPM. We based the 3,000 RPM of the H220(/X) pump on the fans noise level so that when everything is at full speed the pump noise is covered by the fans. Having the 4,500 RPM model in a relatively simple loop like this not only would be overkill but it would be overall noisier. True, both pumps are PWM controllable but unless one's got the means to control the pump and fans individually, the pump would still be noisier than the fans at full speed.
So the pump is still 3,000 RPM but it's an improved version on many different levels. Both pump design and pump manufacturing were really challenging because we had never designed or produced a pump from scratch before. It may sound trivial but it really isn't. Considering the area of expertise of Swiftech, designing and more importantly implementing a flawless production line for such a complex product is probably our finest achievement so far. True, they were issues and we pride ourselves in taking care of customers. That being said, at this point we are really confident in the enhanced design, production and QC.Edited by stephenm - 1/10/14 at 9:26am
