Surface pump is�.
Ultra-efficient � uses less power than any other pump in its range, starts pumping in low light conditions
economical � reduces power sysytem cost by 25-75% compared to centrifugal or ac pumps.
Rugged and reliable � proven design with a 20 year life expectancy
simple to maintain
good tolerance of dirt and dry run
easy-to-install
high lift and flow (great for high-lift applications)
suction capacity
25 vertical feet (7.6m) at sea level. Subtract 1 foot for every 1000 ft. Elevation (1m for every 1000m). Suction capacity may be further limited by intake pipe friction or gasses in water. For best reliability, place the pump as close to the watersource as possible.
Construction
multiple diaphragm industrial design
cast aluminum pump body
neoprene diaphragms backed by pistons
non-toxic oil-filled crankcase
massive ball bearings
permanent magnet dc motor
gear (timing) belt drive
pressure relief valve included
flexible intakeoutlet hoses included
power system requirements
solar (pv) array: chart indicates power (watts) required at the pump. For solar array-direct (non-battery) systems, the rated power of the pv array must exceed the pump watts by 25% or more.
180v models: use a multiple of
10 modules in series.
Linear current booster (pump controller) is required to facilitate starting and to prevent stalling in low-light conditions.
