This legal is a design and specification standard for steel and metallic polymer centrifugal pumps with horizontal designs, end-suctions, single stages, and centrifugal discharges. It covers the whole industry. This standard specifies requirements for dimensional interchangeability as well as specific design elements to increase the dependability and safety of B73.1 pumps. These requirements are intended to make installation and maintenance easier. The purpose of this standard is to ensure that pumps of the same standard dimensions can be interchanged regardless of where they were sourced from. 
This includes the dimensions of the mounting, as well as the size and location of the suction and discharge nozzles, the entrance to the shaft, the base plates, and the foundation bolt holes.

End suction pumps are available in a variety of sizes and materials of construction, including iron, bronze, stainless steel, or corrosion-resistant plastic, as well as impeller designs to handle anything from water to abrasive slurries. End suction pumps are also available in a variety of impeller designs to handle water.
- Mounting in either the vertical or horizontal plane
- Close-coupled for a minimal footprint
- Enclosed or open impeller designs
The casing and impeller of an end-suction centrifugal pump frequently have the form of a volute. 
The fluid is drawn in through the suction end, where it then moves along the impeller vanes, where its speed is increased, and finally into the helical sleeve, where its high velocity is turned into high pressure before being expelled out the top. The housing, the suction, and the vacuum nozzles are normally all contained within a single chamber with this design. On the other hand, if the casing splits in a plane that is either vertical or horizontal with regard to the impeller, the pump is referred to as a split casing pump. In applications requiring a high flow rate and in which the impeller may be supported by bearings on both sides, it is recommended to use a casing design of this sort. The single-stage suction pump is the category of centrifugal pump that is used the most frequently. Its straightforward construction has been a success for generations! Fluid is forced into the inlet of the centrifugal pump, where it then enters the eye of the impeller. This is the fundamental operating principle of a centrifugal pump. The wheel is driven and rotated by mechanical means such as an electric motor, a motor, etc., among other examples. The rotation of the impeller generates a centrifugal force that drives fluid along the impeller vanes and directs it to the outer end of the impeller vane, where it then enters the housing of the helical pump. The intrauterine device (IUD) has the appearance of a "snail shell," which directs fluid around the IUD housing and then breaks it apart using a "cutter" or "breaker." 
The water is split between the discharge and the recycled liquid that is contained in the helical sleeve by the separator as well as the water breaker. End-Suction Single-Stage Centrifugal Pumps are used to supply water, boost pressure in industrial settings, move fluids, provide ventilation, air conditioning, heating, and cooling, and water crops and fields. The rotational kinetic energy of the impeller is converted into the hydrodynamic energy of fluid flow by centrifugal pumps, which are used to move fluids. Fluid enters the pump impeller along or near the axis of rotation, is accelerated by the impeller, and then flows radially outward into a diffuser or helical chamber (housing) from where it spews. This process is repeated until the fluid exits the pump. Typical applications include the pumping of water, sewage, agricultural products, petroleum, and petrochemicals. The high flow capabilities, compatibility with abrasive solutions, mixability, and comparatively simple geometry of centrifugal pumps are frequently what sway consumers to select these types of pumps over others. Numerous household, commercial, and industrial applications might benefit from the utilization of peripheral suction pumps. Because they are in such high demand and can be purchased from a wide variety of suppliers, they are frequently offered at prices that are quite appealing. 
Low-cost standard water pumps are typically made of ordinary iron or a variety of plastic materials, and their couplings are frequently very close together. Pumps are often mounted on a base plate for use in more demanding industrial applications, and a connection is placed between the pump and the motor to keep them separate. For applications involving slurries in mining, dredging, and mineral processing, they are frequently supplied in stainless steel, alloys, or more unusual polymers for resistance to corrosion. Alternatively, they may be made of hardened iron. Terminal suction pumps can be fitted with open impellers for use in applications involving chemical or food processing that may contain particulates, or they can be fitted with closed impellers for use in services involving generally pure water and oil. Standards such as the ANSI B73.1 Chemical Pump Services Standard or the API 610 Hydrocarbon Processing Standard might be incorporated into their design if desired. It is possible for the pump shaft to be sealed off from the outside world by using either conventional or mechanical seals. Alternatively, the pump could be of the magnetic drive type or the wet drive type.
