Centrifugal Pumps: Basic Concepts of Operation ...
www.plant-maintenance.comFigure B.03: Cut-away of a pump showing volute casing o One of the main purposes of a volute casing is to help balance the hydraulic pressure on the shaft of the pump. However, this occurs best at the manufacturer's recommended capacity. Running volute-style pumps at a lower capacity than the manufacturer recommends can put

fristam.caFristam offers both volute and non-volute (circular) housings in many sizes to best match different process needs. The 700 and 1700 series pumps are non-volute and designed for lower capacities. Their shorter, steeper curves provide better efficiencies on low flows and superior accuracy when used with control devices. The 1050, 1150, 3400 and 3500

Prosoli - Centrifiugal Pumps Overview
www.mi-wea.org• The shape of the volute casing is such that it is wider at the discharge point than where the liquid is first forced by the impeller against the volute. • When the water from the impeller strikes the side of the volute, the velocity is increased. This accelerated motion is called “Kinetic Energy”, which is the energy in motion.
Bearings in centrifugal pumps - SKF
www.skf.comThe casing is designed to direct the fluid flow from the impeller into the discharge piping. In a theoretical situation at BEP, the volute casing has a uniform distribution of velocity and pressure around the impeller periphery, see figure 1.10. In a real volute at the BEP, the flow is most like that in the theoretical volute except at

The concentric casing eliminates vibration, turbulence and aeration that is caused by the cutwater point in conventional volute pumps. It also reduces the high bearing loads and shaft deflection
