Aquatec 550 - AC Pump, Fortified

Aquatec 550 Series Booster Pump, 115 Volt AC Version 2 Now "fortified" to IP65 which further resists moisture and dust. 1/2" barbed intake included. A medium duty booster pump, 550 series pumps are appropriate for applications that include drawing water from a holding tank or shallow water source and pressurizing household plumbing; as well as moving water from one location, over distance or uphill, to another location. A booster pump is intended to be placed near the water source with a maximum draw on the intake side of 11 feet of lift (de-rate by 1' for every 1000' above sea level). Despite this capability, Backwoods always recommends a foot valve on the intake pipe when drawing water up from a source, to help keep the intake primed.  An optimum configuration would be to supply gravity fed water from an elevated holding tank or cistern to the pump's intake to drive household's pressure tank and plumbing. Backwoods features a model that includes a standard 5 chamber diaphragm pump head, a permanent magnet motor, quick disconnect inlet/outlet ports, and a built-in pressure switch (cut-in at ~45 psi, shut-off at 60 psi).  1/2" barbed intake and outlet port fittings are included. These are ideal for connection to flexible hose to act as a shock absorber for pump vibrations. Order our P-EZ kit separately if desired.  The built-in pressure switch is NOT adjustable.  Backwoods has an external Square D pressure switch that can be used instead, to operate the pump at lower, adjustable pressure settings for lower power consumption. The 550 is a higher volume booster pump, capable of 5.6 gallons per minute at no head/pressure; and a maximum pressure capability of 70 psi(the equivalent of 161' of lift) with a delivery of 2.9 gallons per minute.  At half power, the pumps can run for extended periods of at least a couple of hours with no heat concerns; BUT running at higher pressures than ~15 psi should be limited to runs of 20 minutes at a time to avoid overheating.  This is a possible issue to consider with very large pressure tanks that take a long time to fill, but easily avoided with a medium pressure tank that can be charged to full in 10 minutes or less. Power draw at no head is 0.89 amps, up to 2.10 amps at 70 psi. Although newly fortified, the diaphragm pump head does have parts that will wear out over time and are field serviceable.  Backwoods stocks the most commonly needed Lower Housing Assembly that includes the diaphragm and "wobble" bearing, and the Valve Housing Assembly that has the actual valve manifold.  Typical service life for these parts are 2 to 5 years.  Reduced GPM volumes over time indicate that the diaphragm and valves are suffering wear.  This pump is capable of being run dry.
