Back ward curved vanes only suitable for Better centrifugal force, because the pumping medium slip well when it rotating, because of centrifugal force pumping medium throw without restriction by impeller:
there are three major types vanes are used for a centrifugal pumps those are 1.forward curved vanes 2.backward curved vanes 3.flat vanes
continuous discharge and centrifugal discharge pumps
No, they are reciprocating.
You'll be able to pump twice the volume.
Vertical turbine pumps are centrifugal pumps mounted vertically. They operate on the same principals as all centrifugal pumps operate, with a rotating impeller around a central shaft. Vertical turbines can be found in single or multi-stage applications requiring high volume, high lift, as well as high discharge pressure.

Centrifugal pumps
A centrifugal pump works by using centrifugal force. A multi pump is short for a multistage centrifugal pump with two or more impellers.
The four centrifugal pumps are the charging pump, sand pumps, shear pumps, and submersible slurry pumps. The machines are used for fluid transportation by rotational kinetic energy to hydrodynamic energy conversion.
continuous discharge and centrifugal discharge pumps
Yup. I do have. I have gear pumps, water pumps, diaphragm pumps, vacuum pumps and blowers, submersible pumps, centrifugal pumps and filters.
No, they are reciprocating.
Gear pumps. A vane pump. Piston pumps. Radial pump. Centrifugal pumps.
Yes

generally, centrifugal pumps are high discharge, low pressure generating pumps. to increase the pressure generated it is setup in stages wherein pressure increases from one stage to an other.mostly seen in daily life applications such as pumps for water tankers. even emergency fire fighter vehicles use these type of pumps. these are called dynamic or non-positive displacement pumps.
positive displacement pumps will always be more efficient than centrifugal pumps due to a centrifugals inherent internal fluid slip recirculation and losses.
