Back to Basics: Pump Types – End Suction Vs. Double Suction

There are often multiple pump types (Table 1) that can be selected for the same water application, with each pump type having its own strengths and weaknesses. This column tries to help guide the reader in the selection of the best pump type that will yield the greatest reliability and lowest life cycle cost for a specific application.

End Suction Water Pumps

An end suction water pump would probably have the lowest initial cost for most applications, with reasonable efficiency. However, these pumps do not follow any standards, especially with regard to bearing life, shaft seal housings and dimensional interchangeability. They are also typically constructed with the lowest cost materials, such as cast iron casings with bronze or brass impellers. The impellers are typically of closed construction, without replaceable casing or impeller wearing rings. Further, there is typically more deviation from published performance, such as efficiency, for this pump type.

Rotary Pump Power

For non-critical, intermittent service applications these pumps may be the best choice. However, for critical applications, requiring long operating life, the cost of maintenance and down time may far exceed any initial cost savings.


End Suction ANSI/ASME B-73 Pumps

Chemical pumps (figure 1), which can handle corrosive, and/or toxic liquids and slurries, are available in a variety of configurations and materials. Pumps used in this industry are different from those used in other industries, primarily in the materials of construction and the many mechanical shaft seal configurations available. These pumps must also meet the American Society of Mechanical Engineers ANSI B73 standards, which require dimensional interchangeability, minimum bearing life, and many other quality specifications. The minimum casing material is ductile iron, with stainless steel being quite common. Typical construction is an adjustable open impeller, which is also good at handling entrained air.

Because of these upgraded features, reliability focused users will typically select an ANSI/ASME B-73 pump over a lower cost water pump for other critical applications, including water services.

Industrial Horizontal End Suction Pump is Easy to Install and Maintain

The Vertiflo 1400 Horizontal End Suction Pump is designed for process, pollution control, spray systems, deionized water, waste water, corrosive liquids and chemicals. Rugged heavy duty cast iron frame design incorporates integrally cast support and ribbed mounting feet which assure a solid, dependable pump installation and operation. One frame fits all pump sizes. The frame has a back pull-out design feature, which allows for easy inspection or service / maintenance without disturbing the piping to the pump. The pump has external impeller adjustment and the semi-open impeller design accommodates passage of solids or fines. All impellers have balance holes near the hub which reduce thrust load and pressure in the packing or seal area. Wiping vanes reduce axial loading and prevent dirt from entering the sealing area. Packing or various mechanical seal arrangements are available as standard options. The pump is offered in a variety of materials: Cast iron, 316 stainless steel fitted, all 316 stainless steel, or CD4MCu. Requirements for pumping clear and corrosive liquids can be satisfied with capacities ranging up to 3600 gallons per minute, heads of 275 Feet and temperatures of 250 degrees F.
