In 1984, Elliott launched the first of 32 Service Centers located throughout the world. In 1987, the management of the Elliott Company returned the firm to independent operation through a management buyout. [2] In 2000, Ebara Corporation of Tokyo, Japan, an Elliott licensee, purchased Elliott. Ebara Corporation is a large manufacturing and ...
Ebara Corporation is a publicly traded manufacturing company based in Tokyo, Japan which makes environmental and industrial machinery such as pumps and turbines. It is the owner of the Elliott Company in the United States and Sumoto S.r.l. in Italy. [5] Ebara also operates through its "WaterKiosk" partnership to supply clean drinking water in ...
Pump and volute casing. A volute is a curved funnel that increases in area as it approaches the discharge port. [1] The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, maintaining the velocity of the fluid through to the diffuser. As liquid exits the impeller it has high kinetic energy and the ...
Casing and tubing flow: means that there is tubing within the casing that allows fluid to reach the surface. This tubing can be used as a kill string for chemical injection. The tubing may have a “no-go” nipple at the end as a means of pressure testing. Pumping flow: the tubing and pump are run to a depth beneath the working fluid. The pump ...
Another type of self-priming pump is a centrifugal pump with two casing chambers and an open impeller. This design is not only used for its self-priming capabilities but also for its degassing effects when pumping two-phase mixtures (air/gas and liquid) for a short time in process engineering or when handling polluted fluids, for example, when ...
The surface casing serves as a foundation pile for the well which transfers the hanging load to the earth. The casing head is prepared with a bowl into which the slips sit and chuck the casing in place. Most casing heads allow for the pressure readings to be taken on the annulus and provide the means to pump out or into if necessary. The top of ...
In general well heads are five nominal ratings of wellheads: 2, 3, 5, 10 and 15 (×1000) psi working pressure. They have an operating temperature range of −50 to +250 degrees Fahrenheit. They are used in conjunction with ring type seal gaskets.
Redundancy is built into the system so that in the event that any one pump is out of service, the remaining pump or pumps will handle the designed flow. The storage volume of the wet well between the "pump on" and "pump off" settings is designed to minimize pump starts and stops, but is not so long a retention time as to allow the sewage in the ...
