Working principle:
Peripheral pumps with the peripheral edge of the impeller
containing numerous radial blades are designed to yield energy to
the fluid being pumped. The particular shape of the blades rapidly
transfers radial recirculation motion to the fluid on entry to the pumps,
between the impeller blades and the double channel, machined on
each side of the pump bodies. Since each blade helps transfer energy,
the fluid pressure increases progressively as it passes from the
suction opening. This ensures an even non-pulsing flow and high
pressure with particularly steep curves. The relatively simple
construction technology embodied in the series nevertheless requires
particularly accurate mechanical machining during manufacture to
prevent a drop in performance

Application:
These pumps are suitable for handling clear water without abrasive
particles and fluids which are not chemically aggressive to the pump
components. They are reliable, economical and simple to use; suitable
for domestic applications, such as the automatic distribution of water
from surge tanks, watering gardens and boosting insufficient main water pressure.
