Comparison of different types of blood pumps Nowadays‚ there are two main types of blood pumps: kinetic pumps and positive displacement pumps. Kinetic pumps: Centrifugal pump is one of the most familiar kinetic pumps. A centrifugal pump converts the input power to kinetic energy in the liquid by accelerating the liquid by a revolving device - an impeller. The most common type is the volute pump. Fluid enters the pump through the eye of the impeller which rotates at high speed. The fluid is accelerated
