HD (Heavy Duty) models include a wider diameter motor with a powder coated shell, cast aluminum endbells and lower housing to improve pressure capability and life. in configurations up to 6 GPM (23 LPM) and 60 PSI (4.1 BAR), these pumps deliver exceptional performance. Standard models provide good performance in an economical footprint. These configurations are in 1-3 GPM, perfect for vessels with 1-3 outlets. A plastic housing protects the motors on these units from corrosion.
