Aquatec DP550 Delivery/Demand Pump
Aquatec’s 550 Series delivers powerful flow rates up to
5.5 GPM/21 LPM at pressures up to 80 PSI/5.5 Bar.
Our patented 5-chamber diaphragm and piston design
allows these pumps to operate at exceptionally quiet
noise levels and with minimal pulsations.
Like our smaller, 3-chamber 5800/7800 Series, these
pumps are designed for intermittent duty, though most
models can be run continuously for hours at a time.
These pumps are commonly used either to pressurize
water from an atmospheric tank,to deliver purified water
to a specific point of use, or simply to increase pressure
These pumps can either be controlled by a pressure switch (“demand” mode) or an external
power control device (“delivery” mode). When required, an integrated bypass can be
incorporated to help regulate pressure levels.
POWER: Available motors from 12VDC to 230VAC, energy requirements between 50W-200W
(depending on flow, pressure). Can be used with compatible transformers and/or DC
power supplies, to be ordered separately. Standard terminations are 12”, stripped end
AWG leadwires, with connectors and power cords also available
ENVELOPE DIMENSIONS:: Approximately 4”x 5”x 8”, weighing 8 lbs
