Additional Details ------------------------------ Product description: GE Merlin 1240632 Booster Pump: The GE Merlin Booster Pump 1240632 increases line pressure up to 60 psi. The pump is used on the supply line. We strongly recommend the GE Merlin booster pump with all GE Merlin purchases because the Merlin operates best at 60 psi. The Merlin pump is a special variable speed pump that is made especially for the membranes in the Merlin system. If your feed water pressure is below 45 psi, the GE Merlin Pressure Booster Pump is a required part for the GE Merlin RO System to operate properly. The GE Merlin reverse osmosis system works on water pressures of 40 psi (2.8 bar) minimum to 80 psi (5.5 bar) maximum. Water pressure can be reduced by installing a pressure reducing valve in the water supply pipe to the RO system. This GE Merlin booster pump should be used for low pressure applications.Continuous cycling of the pump is normal when the pump is used with the GE Merlin system. The GE Merlin Booster Pump is designed to synchronize the proper pressure and flows to the GE Merlin Reverse Osmosis System to gain optimum efficiency and permeate recovery. Some benefits of the GE Merlin Booster Pump are that it increases flow and total GPD output and improves TDS water quality. The GE Merlin Booster Pump is manufactured by Aquatec for the GE Merlin Reverse Osmosis System. The Aquatec part number is 5501-IVN2-V77DUL or 5501-1EN2-V77D. The GE Merlin 1240632 Pressure Booster Pump can help to resolve the following problems: low driving pressure, low water temperature, and high total dissoved solids (TDS).
