[QUOTE="user 12139, post: 648738, member: 12139"] your on the money there Simmo. Its best to have the suction running as efficient as possible by minimising suction frictional pressures which in turn helps to prevent pump cavitation. Cavitation is the leading cause of premature impeller and housing wear. So as Simmo suggested stick to your 3" suction and choke back on the discharge and revs. Just keep an eye on the impeller housing temp, you dont want it getting beyond warm [/QUOTE]
