KSB Centrifugal Pump Lexicon
To this end, centrifugal pumps in suction head operation are equipped with a vent valve or a manually operated air vent at the pump casing's apex. Venting systems use water ring pumps or jet pumps (see Eductor-jet pump).
Diving into Pump Casing Designs: Exploring Common Types and ...
2023年11月22日 · The advantages this design offers include self-venting for vertical discharge arrangements, the casing hanging straight when lifted by the discharge flange, and the weight of the casing being equally distributed to both feet.
The pump casing provides a pressure boundary for the pump and contains channels to properly direct the suction and discharge flow. The pump casing has suction and discharge penetrations for the main flow path of the pump and normally has small drain and vent fittings to remove gases trapped in the pump casing or to drain the pump casing for ...
Centrifugal Pumps Review - Engineers Edge
Centrifugal pumps basically consist of a stationary pump casing and an impeller mounted on a rotating shaft. The pump casing provides a pressure boundary for the pump and contains channels to properly direct the suction and discharge flow.
Fundamental Pump Components: Volutes, Casings, and Impellers
When you boil them down to the most fundamental components, pumps are made up of two components: An impeller which creates velocity through rotation, And a casing which converts velocity into pressure. There are different types of impellers and different types of casings.
Self-venting pump - Pump engineering | Eng-Tips
2012年3月26日 · Self-venting pump - a pump whose casing can be flushed of entrained gas by simply opening its suction and discharge control valves and rotating the shaft manually prior to starting. The pump casing does not have a vent connection.
Pump casing - KSB
Pump casings serve to seal off the intside of the pump to atmosphere to prevent leakage and retain pressure. In the case of centrifugal pumps they surround the pump rotor which transmits energy to the fluid handled via the impeller (s) mounted on the rotating shaft.

2017年8月12日 · The external, visual face of the Pump Casing includes these common features: Suction Flange fabricated to mate with the Suction Line Flange. Body to accommodate the number of pump stages/impellers. Horizontally-Split or Vertically Split construction for ease of access to the rotor. Discharge Flange fabricated to mate with the Discharge Line Flange.
Pump Casings: A Comprehensive Guide to Materials and Designs
2024年11月5日 · A pump casing is the outer shell or structure that encases the internal components of a pump, particularly in a centrifugal pump. Its primary purpose is to provide a containment area for the fluid being pumped, while also …
Vented Pump Casing - Polaris Pumps
Vented Pump Casing. Four circumferential casing vents connect the mechanical seal chamber to the sump ensuring that the motor mechanical seal arrangement is never exposed to pressures in excess of submergence depth x slurry density.
