Slow speed pump

Webb13 apr. 2024 · High Pressure Piston Pump. Hello, I have a high pressure piston pump that will run LNG at 310 barg and -150°C. I was told that at slow speeds it would cavitate. I don't see why slow speeds would cause cavitation as slowing a normal pump down is one of the ways we solve cavitation in other pumps. Any insight would be greatly appreciated. Webb15 okt. 2024 · If your motor was NOT selected as inverter duty and does not state a turn down ratio, I typically tell people to assume no better than 4:1, so 15Hz as the slowest speed. You say you are already running at 10Hz, so hopefully this is not the case and someone knew what they were doing.

WebbAs pressure on a pump increases, the power required decreases. In other words, if you put a valve on the discharge of a pump and begin to restrict the output flow, the power required by the motor will decrease. Most people already have it in their head that choking a pump back will make the pump work harder and use more power. Webb13 apr. 2007 · 04-04-2007, 09:58 PM.
