ANSI vs. API Durco Pumps

Many plants use both ANSI pumps and API pumps. However, it can sometimes be difficult determining the right pump to use for certain applications. Some people end up buying ANSI Durco pumps for tasks that require API pumps. It is important to understand the difference between the two types of pumps to help you make wise purchase decisions.

The ANSI Pump
The design of an ANSI pump meets the requirements of the American National Standards Institute. ANSI pumps have become the most preferred end suction pumps. This type of pump can be used to pump chemicals, water, and other substances.

The API Pump
API pumps meet the criteria set by the American Petroleum Institute for general refineries services (standard 610). These pumps are almost exclusively used in oil refinery industries because of their pressure and temperature resistance features.

The Service Considerations
Industries in both chemical and petrochemical sectors consider many factors in their operations. Other than environmental impact and the pumping efficiency, personal safety must also be considered. Therefore, consider operating conditions and the properties of the pumped fluids when choosing between ANSI pumps and API pumps.

The pump packing and casing design rating of ANSI and API pumps vary:
• The rating for ANSI pumps is 300-psig at 300-deg F
• The rating for API pumps is 750-psig at 500-deg F

This makes API pumps more preferable for high temperature and high pressure applications than ANSI pumps.

Case Designs
Both pumps have a single radially split casing design. This design helps to ensure easy maintenance. Majority of ANSI pumps and a few API pumps engage one volute design inside their casing passages. However, many ANSI pumps and some API pumps feature a single volute design on the inner parts of their casing. This is especially true for smaller pumps with low flow rates and impeller speeds. The rate of discharge from the impeller is usually proportional to the area of the volute. This creates a constant velocity at the impeller’s periphery.

Most large API pump designs have a double volute to reduce loads applied on high head and high flow units. The reduction is possible through balancing loads in each volute. This may cause a decrease in efficiency but the pumps have an increased long-term reliability.

Back Cover Arrangements
The back covers of API and ANSI pumps are secured differently. In an ANSI pump, the gasket and back cover is held to the casing by a bearing frame adaptor usually made from cast iron. This back cover arrangement causes a gap to form between the pump casing and frame adaptor that may permit uneven torques of the bolts. As a result, the adaptor may fracture if the casing is exposed to high pressures. An API pump design has the back cover directly bolted to the casing, which does not affect the pump casing’s pressure boundary.

The current Globally Harmonized System (GHS) is a method by which safety information as it pertains to specific products is communicated in a standard format internationally. The two major elements of this system are Safety Data Sheets (SDS) and safety labels. Because of their effectiveness in overcoming language barriers, GHS pictograms are a major part of the new GHS labels.

GHS pictograms are basic symbols that that give indications to viewers that one or more hazard types may be associated with that particular chemical. They consist of a red diamond-shaped outline with a symbol printed in black inside. These symbols can indicate things like health hazards, flammability, contents under pressure, explosion or environmental hazards. They are, however, just one of the several label requirements of the GHS classification system.

Responsible Party Identification

The label must include the name, address and phone number of the product manufacturer, importer or other responsible party. This gives users of the product quick access to a source of more detailed information if it is needed quickly. It also provides a bit of accountability for the accuracy of the information on the label and associated SDS.

Product Identifier

The product identifier is basically the product name as chosen by the manufacturer or distributor. It can consist of a name, batch number or both. It is important that the same identifier be used on both the label and SDS for easy cross-reference.

Signal Words

Only one of two possible signal words is used: “danger” and “warning”. “Danger” indicates hazards that are more severe while “warning” is used for hazards that are less serious. Only one of the two signal words are used regardless of the number of hazards present. In this case, the word for the more serious hazard is to be used.

Hazard Statement

The hazard statement is chosen from a long list of standard statements that describe hazards of various chemicals. This is to ensure that the same statement will be used by all manufacturers of chemicals of the same category. An example of a hazard statement on a GHS label is “causes severe skin burns and eye damage”. Unlike the signal word, all the applicable hazard statements are used, so it is common to see two or more listed.

Precautionary Statements

Precautionary statements are brief descriptions of measures that should be taken to prevent or minimize adverse effects from exposure to the chemical. The four types of statements are related to prevention, response, storage and disposal.


There are nine available pictograms that can be used on GHS labels.
● Health hazard
● Flame
● Exclamation mark
● Gas cylinder
● Corrosion 
● Exploding bomb
● Flame over circle
● Environment
● Skull and crossbones

As opposed to previously used systems, these label requirements provide consistency in the way products are labeled in order to more clearly communicate hazard information to product users. If you want to learn more, visit ICC Compliance Center.

Vortex Industrial Cabinet Coolers

Modern day technological systems and devices are ingenious. They are indispensable. They have revolutionized labor and consequently, life. They make the American economy so much stronger than ill-developed countries. However, with almost every first world nation embracing industrialization, only the small things matter. Almost all possible discoveries and inventions possible for this generation have been unearthed and patented. The secret to wielding the upper hand in the competition for optimizing productivity in the world of cutting-edge technology may lie in a very simple secret: cooling electronic control panels with vortex coolers.
Malfunction induced by overheating of electronics is commonly referred by industrial players as ‘cooking’. It is extremely detrimental for manufacturers and other industries that heavily rely on electronics to experience ‘cooked’ systems. Circuit breakers trip causing power surges due to overheating. Overheating also causes digital displays to misread and controls to drift. Nuts and Bolts may also melt permanently shutting jointed hinges hindering locomotive functions of machinery. For extremely sensitive wiring, plastic may melt causing electronic short-circuiting and possible eventual fires. Cooling is essential, and if not efficiently administered, plundered productivity is inevitable.
Vortex cabinet coolers are considered to be the current top-notch industrial coolers yet to exist. Profitable and reputable American companies use this industrial cabinet cooler to maximize their productivity. They avert overheating by utilizing coolers that will provide air conditioning for electrical runs to eliminate electric control downtime owing to moisture, dirt and heat. Vortex tubes are incorporated in these cooling systems for encasement. Cold air is produced without any shifting parts from the compressed air. The vortex coolers thus sustain little cabinet pressurization. The electric components consequently remain clean and dry. The coolers are furthermore regulated by thermostats to control the cabinet temperature.
While other countries toil to create perhaps machines that use up to four times the power needed to archive milestones, we should cut the power usage. Avoid using fans and liquid coolant pipe systems to cool industrial systems. These cooling schemes and methods are
1. Inefficient
2. Space inefficient
3. Expensive
4. Messy (a source of further contamination)
Air conditioning fans consume too much electricity and expel minimum heat. They suck in air that is humid and contaminated. As a result, particles clog the intricate systems leading to reduced efficiency and lifespan of the systems.
Piped cooling systems, on the other hand, take up too much space and consume coolant fluids that require cooling and replacing. More information can be found at Pelmar Engineering Ltd., providing you with additional resources and references.

Package Leak Detection Prevents Lawsuits

How Leak Detection Equipment Can Prevent A Lawsuit

The right package leak detection equipment can prevent your business from being sued over mishandling. From customer packaging to the final delivery, there are many steps, which can make it difficult to discover when the parcel was damaged. Leak detection devices can create a better “chain of custody” when identifying cracked, broken or destroyed containers through the following phases:

1. Customer Seals
2. Employees Distribute
3. Drivers Deliver

First-class companies prevent potential leaks from harming their employees, customers or reputation.

1. Customer Seals Package
Individuals might not be experts at sealing their special items in a box. The box might not be large enough, there might not be enough interior filling or the outside seals might be inferior. Most cardboard boxes will deteriorate when they get wet. High humidity could lead to perspiration on cardboard containers.

Restaurant food ingredients, sensitive electronic equipment, jewelry and medical specimen might need to be placed in special containers. Many employers are requiring drug tests and collecting fluid samples, which are sent out to laboratories every week. Some of these medical containers could contain contagious diseases.

2. Parcel Moves Along Conveyor Belts
High-quality package leak detection equipment could be located before the parcel arrives at the sorting warehouse. Any damaged packages could be removed to prevent the entire facility from being contaminated by gases, liquids or solids.

Although, each package delivery company has its own specific process, many will take the cargo from their trucks and distribute them to the proper geographical containers using conveyor belts. The packages must be loaded onto the belts and then unloaded into the containers, which could involve rubbing, abrasion or drops. Sensitive seals could be damaged at this stage. Leak detection equipment could scan the packages before they are loaded onto the containers.

3. Truck Loading & Delivery
The finally stage involves unloading the containers for placement on delivery trucks. Before the parcel is loaded, it should be scanned to prevent contamination of the vehicle. The delivery driver passes through many neighborhoods and should not endanger the health of his customers.

Just as customers can now track the movement of their cargo on the Internet, they could also be given a simple “condition” assessment online. When the damaged package was “identified” could be clearly marked. If there are any lawsuits, this could be used as evidence.

Your business reputation depends on maintaining control over your packages and work environment. By pro-actively installing leak detection devices, you create the means, methods and ability to accomplish this goal. Demonstrate your commitment to excellence and quality control, by preventing potentially dangerous leaks from harming your employees, facilities, customers or reputation.
