Practical Considerations in Pump Suction Arrangements

The single most important function of a pump suction system is to supply an unencumbered, evenly dis-tributed flow to the pump. This is true regardless if the intake configuration is a single pipe, an open sump, or a river. Secondly, the pump suction system should not promote the external introduction, or in-Get price

Mixed flow pump | KSB

A mixed flow pump is a centrifugal pump with a mixed flow impeller. The specific speeds (ns) lie between 35 and 80 rpmfor low-speed mixed flow pumps, and between 80 and 160 rpm for higher-speed mixed flow pumps (in special cases even higher). Mixed flow pumps cover the transition range between radial flow pumps and axial flow pumps (e. g. propeller pumps).Get price

Vacuum pump - Wikipedia

A vacuum pump is a device that draws gas molecules from a sealed volume in order to leave behind a partial vacuum. The job of a vacuum pump is to generate a relative vacuum within a capacity. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity.Get price
