Disc pumps are used for difficult pumping applications, such as, pumping of high suspension solids and abrasives, viscous fluids, air entrained and shear sensitive fluids. The pumping mechanism, based on the boundary ...

The disc pump operates using boundary layer principle and viscous drag with a relatively low efficiency. There are methods to increase head and efficiency, one of them is the placing of blades sector sor splitter blades ...

The present study investigated a system of pumping diesel centrifugal pump, used to sell the product to the company producing the next unit in the city of Araucaria - Paraná. In this study we evaluated the system performance ...

The present work analyzes the technical feasibility of solar-assisted heat pumps for swimming pool heating in South Brazil. The methodology is based on computer simulations for four configurations of heating systems for ...

Flow pumps act as important devices in areas such as Bioengineering, Medicine, and Pharmacy, among other areas of Engineering, mainly for delivering liquids or gases at small-scale and precision flow rate quantities. ...

The proposed work consists in the comparison of the application of two systems for the pumping of water. With a pump drive by electric motor and the other by wind mill, in order to demonstrate the efficiency and pay-back ...

Worldwide, many farmers use irrigation systems for their crops. They usually use highpower centrifugal or axial pumps powered by electrical energy or combustion engines. This technique provides increased productivity, in ...
