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
A pump is required to produce blood flow. Currently, roller and centrifugal pump designs are the standard of care.

Actually, its the exact opposite. Newton's first law of motion states that every object will remain at rest unless an outside force acts upon it, proving flow is only caused by an outside force. This force may be gravity or contact with a spinning pump impeller. Pressure is a force per area and the cause of fluid motion. The amount of pressure applied to a fluid determines the flow. _____________________________________________ The paragraph is basically correct for most applications. The previous first line is not, and I've eliminated it. The actual answer depends on the type of pump. The most common pump is a centrifugal pump. This type of pump basically accelerates the fluid (adds velocity). If you measure the pressure at a point at the outside of the volute of a normally operating centrifugal pump, it would be very low as the velocity is high there. At a point in the pipe slightly downstream of the pump, the pressure would be higher as the velocity is lower and the overall energy content of the fluid is essentially the same. The pressure and velocity are related in that both are components of the energy inherent in the fluid. This relationship is the Bernoullli equation. But there are other types of pumps besides centrifugal. I'm thinking positive displacement pumps, like piston pumps, gear pumps, or peristaltic pumps. These pumps increase the pressure of the fluid directly, which results in higher flow in the system as a whole. They are less common than centrifugal pumps, but positive displacement pumps are a very significant share in the world of "pumps". ________________________________________________
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.
