Suction stage
WebThe casing is split axially, with opposing suction and discharge flanges, greatly simplifying maintenance. Filter by application: With balanced bearings and a robust overall design it’s not uncommon to find SPP horizontal split case pumps still in use after 70 years of service. WebSelf-priming pumps have to be capable of evacuating air (see Venting) from the pump suction line without any external auxiliary devices. Centrifugal pumps with an internal suction stage such as water-jet pumps or side-channel pumps are also classified as self-priming pumps. [9] Self-Priming centrifugal pumps were invented in 1935.
