Pump Pressure Vs Flow Rate Testing

Continuing the same test method as before, I’m measuring the pressure capabilities over the complete spectrum of possible restriction scenarios to develop the pump curve. I simply adjust the restriction via my King valve at .5 GPM increments and record the pressure gain or TDH across the pump. My flow meter is a King Instruments 7520 with valve, my manometer is a Dwyer 477-5 digital manometer, and I have fabricated my own 1/2″copper x 1/4″ brass T fittings to avoid adding restriction to the test.

Wow, that is impressive. While most bay reservoir tops struggle to maintain the same level of pump performance as the factory top, XSPC did their homework and improved performance by a noteworthy amount. This is the highest performing D5 top I’ve tested to date which is excellent!!

CASE FIT ISSUE

In a quick fit test into my XSPC H2 case, I noticed a problem with the plastic width dimension right behind the face plate. The plastic measures 5.890″ were the case bay measures 5.870″. This means the plastic is about .020″ too wide and would not slide back into the bay completely. This is easy to fix with a large file or sand belt, but not something you should have to do. This also probably depends on the case, but it is something to be aware of.

    This review is nothing more than an advertisement for the product. You need actual flow rates and pressure measurements to prove if the volute is an improvement. What about noise levels?
