Regent's Vortex Pumps

Regent Pumps Logo
Regent’s Vortex pump range includes the Vorbloc and Superflow Series. Most of these models are derived from the standard Dinflow range and include a recessed impeller which creates a vortex within the pump casing. Smaller models are also included in the range, mainly for marine use. Vortex pumps can be supplied as bareshaft pumps, long-coupled, base-mounted units, close-coupled motor pumps, or long column sump pumps.

Vortex pumps, which are also known as recessed impeller pumps, create circular churning motion around an axis. This motion creates suction to flow into the volute and out through the discharge. Vortex motion may or may not be created by pressure differences of a fluid-solid mixture. Since the rotor is positioned farther back it allows for solids and even gases to pass without direct contact with the rotor. To create an efficient flow with the suspended particles, it is essential to generate a sufficiently powerful vortex to induce suction of the solid particles. This requires a very powerful pumping action with high horsepower. Vortex formations are dependent on fluid properties like density and viscosity. The rotors are also recessed for solids clearance, although at some cost to the pump efficiency.
