Alphacool is announcing today the next evolution in pump technology with the VPP755 Eispump. Built completely from the ground-up, this new pump design throws out all the old problems with the well-known D5 pumps and retains only the compatibility to all current D5 tops and brackets.
The VPP755 Eispump dispenses with the spherical bearing, and opts instead for a ceramic shaft that allows for quieter operation. The motor's coils are now on the outside instead of inside. According to Alphacool, all of these innovations provide more stability, which results in less vibration. It also means the power consumption is cut nearly in half. Yet the VPP755 Eispump still boasts a 4m maximum head for higher performance. The VPP755 Eispump is also distinctly quieter than the classic, well-known D5 pump while providing the same performance.
On the backside of the pump there is a small rotary switch, which has 5 levels for manually controlling the pump. The unique thing here is that the manual control and PWM control can now work together - a system patented by Alphacool. Using the rotary switch, the general maximum RPM for the pump can be set, which then cannot be exceeded by the PWM control. Practically, this means that if the pump is set to level 3 with a maximum RPM of 3200, you can also only reach a maximum RPM of 3200 through the PWM control, allowing for true user-set cooling and noise levels.
