DESC:FIELD
The present disclosure generally relates to the field of pumps and more specifically relates to a multiway casing for a pump.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Generally, Self-priming pumps are employed across a wide range of applications to facilitate the transportation of water from a reservoir to another place. These pumps are commonly employed in water supply systems, irrigation, chemical processing plants, wastewater treatment facilities, and many other fields. These pumps conventionally consist of a casing that houses an impeller. The casing typically comprises a suction port and a delivery port, with the suction port consistently positioned relative to the delivery port. The main function of the suction port is to intake the fluid from the reservoir and direct it into the rotating impeller. As the impeller rotates, it propels the liquid outwardly through the delivery port of the casing.
One of the challenges with traditional pump casings is related to the suction ports and delivery ports. The orientation of these ports is essential to ensure proper flow and operation of the pump. However, the traditional casings have fixed orientations for these ports, limiting the pump's flexibility and adaptability as per the end user requirement.
Another limitation arises from the single suction port and the single delivery port in the traditional casing configuration. This setup restricts the mixing of fluids in line, especially when dealing with two or more fluids in line. And also, this setup restricts the distribution of fluids through multiple ports due to the presence of a single delivery port.
Moreover, the lack of interchangeability in traditional casings hampers their versatility. The end user often encounters situations where they need to change the rotational direction of the casing or the orientation of the delivery port to accommodate specific installation requirements. Unfortunately, traditional casings do not provide this flexibility, leading to additional complexities and challenges during pump setup and operation.
Additionally, in various applications, it is essential to monitor the pressure of the fluid being pumped or to have the option to relieve excessive pressure. However, the traditional casing configuration does not offer convenient access for the installation of accessories such as pressure gauges and relief ports, and thus making it cumbersome to integrate these essential features into the pumping device.
Therefore, there is felt a requirement for a casing assembly for the pump that alleviates the aforementioned drawbacks.

Typically, the traditional casing (200’) of a conventional pump (100’) consists of a suction port and a delivery port, with the suction port consistently positioned relative to the delivery port. The consistent position of the suction ports and delivery ports limits the pump's flexibility and adaptability as per the end user installation requirements. Further, the single suction and the delivery ports in the traditional casing (200’) configuration restrict the mixing of fluids in-line, especially when dealing with two or more fluids in line. Further, a single delivery port restricts the distribution of fluids through the multiple ports. Figure 1 illustrates an isometric view of a conventional casing assembly of a conventional pump.
Furthermore, the end user often encounters a situation where he needs to change the orientation of the delivery port to accommodate specific installation requirements. Unfortunately, the traditional casings (200’) do not provide this flexibility, leading to additional complexities and challenges during pump installation and operation.
To address the issues of the conventional casing assembly of the pump, the present disclosure envisages a multiway casing assembly for a pump.

In an embodiment, the multiway casing assembly (200) is a volute casing.
A method (500) of changing the orientation of suction ports (206a) and discharge ports (206b) of the multiway casing assembly (200) is elaborated below. The method (500) includes steps of,
• removing the second set of fasteners (700) to separate the end cover (206) and the fixture plate (204) from the base plate (202);
• rotating the end cover (206) along with the fixture plate (204) around the longitudinal axis (AA) to the second operative position to align the second set of mounting holes (206f) with the first set of mounting holes (202f); and
• mounting the end cover (206) and the fixture plate (204) on the base plate (202) by inserting and tightening the second set of fasteners (700) through the first set of mounting holes (202f) and the second set of holes (206f).
Hence, the multiway casing assembly (200) for a pump (100) facilitates ease of change in the direction of the suction ports and the delivery ports to accommodate specific installation requirements. Figure 7 illustrates isometric views of the multiway casing assembly with the suction ports and the discharge ports in different orientations, in accordance with an embodiment of the present disclosure.
Advantageously, since the multiway casing assembly (200) is configured with multiple suction ports and delivery ports, therefore it enables the mixing of fluids in-line, especially when dealing with two or more fluids at the inlet. Additionally, due to availability of the multiple delivery ports, the multi-directional discharge of fluids is possible at the same instant.
The fluid flow direction within the casing (200) can be reversed by changing the direction of rotation of the motor shaft (300a).
Each suction port (20b) and each delivery port (20c) can be selectively opened or closed based on the end user requirement. Further, any of the suction ports and the delivery port can be selectively closed by means of a closure cap.
In a preferred embodiment, the multiway casing assembly (200) is mounted on a single shaft of the motor.
As elaborated above, the multiway casing assembly (200), includes three separate components, a base plate (202), a fixture plate (204) and an end cover (206). Advantageously, this split configuration of the multiway casing assembly (200) provides ease of mounting, maintenance and service of the pump.
In addition, the availability of the multiple suction ports and the multiple delivery ports offer ease of mounting or installation of the different accessories such as pressure gauges and relief ports on the casing assembly.
Further, since the multiway casing assembly (200) is externally mounted on the motor shaft (300a) of the motor (300), there is no need of major internal modifications in the motor to accommodate multiway casing assembly (200). Therefore the multiway casing assembly (200) is compatible with existing self-priming pump models. The multiway-casing assembly can be retrofitted in traditional pumps for cost-effective upgrades.
