Yes, Volume! Not only pressure. All self-cleaning centrifuges have a specific flow rate of bowl closing water needed to close the bowl. We often find that the flow rate is too low even though the water is under the right pressure. For a typical Alfa Laval centrifuge, the closing water should flow at a minimum of 3 GPM at the designated pressure.
