Note: You may find pumps listed with the same model numbers as these listed elsewhere. LX is an OEM pump manufacturer, and provide various specifications within the same main model numbers. Versions listed crazy-cheap elsewhere have lower-grade seals, impellers, have no Electrical Approvals, and are illegal. There is only one importer that ensures the highest-specs are sold, and tracked via serial numbers. We only sell the electrically-approved version.
