The optional precompression volume cuts pressurization pulsation in half and reduces fluid-borne noise. And the housing was designed using modal analysis to reduce body-borne noise.

Engineers also improved the rotary group and suction channel, increasing pump efficiency by 3%. These improvements help the pump resist sudden reductions in suction pressure, as well as pressure spikes. A new generation of valves lets operators make leak-free adjustments and increase output pressure.
