What is a Pump Casting?

 

 

Pump casting is a process cycle in which pump parts are planned and projected by various metals or metal compounds. It can give more prominent strength and erosion resistance items and manage fluid substances.

 

Guidelines for Designing and Pump Casting Castings

 

Select a foundry that has specific experience in casting pumps or pressure castings.


Be thorough and accurate when developing quotation requests. Information such as quantities, type of metal required, casting weight and special items such as annealing or stress relieving, certifications and letters of compliance should be included in the formal quote request. Also include the terms of payment, shipping instructions and any special packaging requirements.

 

Supply a legible set of blueprints or CAD files. Such files should include locations where brinell readings are to be taken on the castings, as well as tooling points, the desired parting line and draft angles and the tolerance of angles, radii and dimensions.

 

Quotation responses should specify the part number, revision level, casting weight, piece price, quantity breaks, minimum billing, current metal surcharge, pattern material, number of impressions, the number of impressions in the core box and the type of machine on which the part will be run.

 

During the design stage of pumps, uniform metal thickness should be maintained when possible. Isolated heavy bosses or hubs have a tendency to create shrinkage and porosity.


The pump design should not include any square corners. Instead, a substantial radius should be included on all corners or transitions. To increase efficiency, sharp 90 deg transitions should also be avoided within the pump casting.

 

Purchasing should not consider or accept quotations that only state "one set of pattern equipment” for a specific part number. During this stage, purchasing may be unaware of what they are buying in the form of tooling…whether it involves inexpensive wood components or metal. Purchasers may not understand the number of impressions on the pattern or the number of impressions in the core box.

In wind turbines, impeller castings are used in the turbine's rotor to convert wind energy into mechanical energy. In solar energy systems, impeller castings are part of the heat exchangers, pumps, and heat transfer fluids, ensuring efficient heat transfer and energy.

 

Why Do We Use Cast Iron Material for Gear Boxes?

 

The preference for cast iron in gear box manufacturing stems from its exceptional mechanical properties that make it an ideal material for this critical component. Cast iron offers superior strength, durability, and wear resistance, ensuring longevity and reliability in demanding operational environments.

 

Its ability to withstand heavy loads and high torque, coupled with excellent heat dissipation properties, makes cast iron the material of choice for gear boxes. Additionally, the casting process allows for intricate designs and precise shaping, optimizing the efficiency and performance of the gears within the gearbox. This insightful exploration sheds light on the compelling reasons behind the widespread utilization of cast iron, underlining its pivotal role in the functionality and durability of gear boxes across various industries.

 

Pressed Metals vs Cast - Do You Know the Difference?
 

Pressed vs Cast Metals

Pumps are available in a wide variety of materials and finishes but one of the most distinct differences in pump construction is that some parts and casings are manufactured from cast metal and others are made from pressed metals. There are big differences between cast and pressed metals, but what are these differences? How do they affect the decision on which pump is best for the process, as well as having the lowest lifetime cost?

So, what's the difference?

Metal pumps can be manufactured using either cast or pressed metals, the main difference being the process in which these metals are shaped.

Pressed metal pumps are manufactured from sheet metal through a forming process. This process changes the shape of the sheet metal into that of the required object. The sheet metal is then cut to size from the required piece, and is then pressed into shape using either hot or cold force. Any fittings which are required such as flanges and screwed connections are welded to the casing. A pump casing can be a combination of between 2-5 separate pieces which are welded to the casing, with the welds being a few mm thick.

Cast metals on the other hand, are often manufactured from molten ferrous and non-ferrous metals through sand casting, lost foam/wax, or investment casting. Additives can be incorporated during casting to create variations of metals; such as magnesium to cast iron – to create ductile iron (spheroidal graphite), or aluminium to copper – to create aluminium bronze. Cast pumps are essentially a single piece of metal without welded parts. Not only is the body cast, but also the internal parts such as impellers and wear rings are cast or machined from a solid bar.

 

Cast Metals

Pressed Metals

productcate-200-200

productcate-200-200

Available in a wide range of materials, ensuring compatibility with a larger range of applications.

Not available in the same number of alloys, as some metals are unsuitable for pressing due to their micro-structure not allowing them to be worked mechanically.

Rugged design due to thick casing casing moulds. Also have a good rigidity to pipe loads, reducing coupling and bearing misalignment.

Sheet metal is usually only a few mm thick, making them much more susceptible to damage when knocked.

Good solid handling capabilities due to the robustness and thickness of the casing and impellers.

Don't handle solids as well, so are preferred for the transfer of clean liquids.

Allow the use of easily replaceable wear rings, which not only wear instead of the more costly casing, but also improve pump efficiency.

Do not use wear rings, meaning that the casing which is only a few mm thick wears quite quickly, hence their lower operating lifespan.

Have an allowance for corrosion within the casing.

Usually laser welded using a filler metal which typically degrades quicker than the casing, and often corrodes when in contact with salt water or chemicals.

Designed to withstand high pressures and radial loads are easily manufactured.

Not designed for high pressure applications.

Easy recyclable as they can be dropped back into a cupola (casting pot) at the end of their life.

After the initial shape has been cut from the sheet, there are leftover pieces too small to make parts from. These would need to be taken to a recycling centre.

More expensive initially, with lower overall lifetime cost.

Smaller initial outlay, with higher overall lifetime cost.

So, which should I choose?

Sometimes, the specification of the pump is simply not possible with pressed metals due their design limitations. For example, pumps for high pressure applications or where they require an overhung bearing design.

 

It is true that typically, pumps constructed in cast metals are likely to be a more expensive initial cost, so pressed metal pumps are usually considered when budget is tight. However, for many of the reasons stated above, they represent the best value of money over their total lifetime due to their durability of design, ruggedness and thickness. As a pump supplier, we would always recommend selecting cast metal pumps over pressed pumps where it is an option to do so.

 

Understanding the 4 Types of Cast Iron

 

 

There are four primary types of cast iron, each produced through different processing techniques:

 

Grey Cast Iron: Grey cast iron contains free graphite (carbon) molecules, providing excellent thermal conductivity and damping capacity. It is commonly used in engine blocks, manifolds, and cookware.

 

White Cast Iron: By controlling carbon and silicon content and cooling rate, white cast iron lacks free graphite, resulting in a hard and extremely wear-resistant material. It finds applications in pump housings, mill linings, crushers, and brake shoes.

 

Ductile Cast Iron: Ductile cast iron's nodular graphite structure offers improved ductility and strength. It is suitable for high-strength components like gears and machinery parts.

 

Malleable Cast Iron: Heat-treated white cast iron transforms into malleable cast iron, providing increased ductility and impact resistance. It is used in shock-resistant applications.
