The 6800 Series is intended for use with RO membranes rated up to 50 GPD. Close tolerances within the pump head and motor, give a lower amp draw; lower operating temperatures; smoother running; longer life; lower maintenance; and greater efficiencies.It incorporates powder coated die cast alloy and a unique label sealing process to reduceexposure to moisture which is the major cause of motor failure. The pump is available with optional EMI/RFI electronic noise suppression to reduce TV reception interference. The PAB6800 Series is capable of operating in a warm, humid hostile environment where other pumpshave been known to fail. It is the strongest, most durable pump available on the market today.Distinguishing Features:• Toughest, most durable pump on the market• Adjustable max. outlet psi.(regardless of feed pressure)• Expels trapped air (no more air locks)• Can be mounted with pump head up or down• More flow at extremely low inlet pressures• New motor venting system to remove moisture• EMI/RFI electronic noise suppression• 100% final performance testedKey Operational Benefits:• Boosts pressure 40 to 120 psi (adjustable)• Fixed pressures to 160 psi• Up to 30,000+ operating hours• Whisper quiet –– less than 45 DBA• Can run dry without damageTechnical Specifications:OPERATION: The 6800 is designed to operate with a PSW tank shut-off switch for hydropneumatic storage systems. The PSW, when used with a typical undercounter R.O. system, can be augmented with an ESO, Electronic Shut-off Valve. It is also compatible with most hydraulic shut-off valves. For counter-top systems, Aquatec's TLC, Tank Level Controllers, shut off feed water and the pump when the product water storage tank is full.POWER: Pumps operate with low energy (only 14 watts), low voltage (12-24 volt) motors, poweredwith compatible transformers with world wide primary voltages available (100 VAC, 120VAC, 230 VAC). FITTINGS: Built-in 1/4" John Guest half cartridge fittings eliminate need for external fittings.INSTALLATION: The location and positioning of the pump may affect it's performance.Always consult Purely H2O for recommendations that will optimize your system.• Self-priming –– 60" lift• Low voltage (12-24V) for maximum safety• Corrosion resistant exterior• Continuous or intermittent operationYour Purchase includes one Aquatec 6800 booster Pump and one transformer....Yes The transformer is included in this product :)Aquatec 6800 Booster pump Transformer 2 year warranty
