This series of electric pump has a peripheral type impeller. This pump is made in this way because on the extremities of the impeller there are several radial paddles, which give more energy to the pumped liquid.

The special shaping of the paddles gives the fluid fast radial recycling motion between the paddles of the impeller and the pump body.

This characteristic enables the fluid to increase progressively the pressure in its way from the inlet to the outlet, obtaining the regular and not pulsating flow and high pressures with quite slopping curves.
