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.

Differences
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.

Industrial Filters

Importance Of Bag Filters In Industrial Use

Industrial processes may generate a great deal of dust, smoke or hazardous airborne gases. The best company will protect the health of their employees by using bag filters to trap all of the harmful airborne contaminants. Clean, healthy indoor air enables everyone to breathe a little easier.

Enable Your Workers to Succeed

Successful business owners give their employees the tools to succeed. As a warehouse owner, you have the duty to establish a high quality of indoor air. Your workers need oxygen to keep their bodies moving and minds operating efficiently.

Worker efficiency can be the difference between a profit or a loss. Naturally, you want your employees to be the most productive during every hour of work. Calculating lost productivity due to health problems can be difficult; but, a healthy, happy workforce will be faster and produce higher quality goods.

Replace Clogged Dirty Fans

Many times, airborne contaminants might be rather invisible or innocuous. When they build up on your warehouse fans, then suddenly you can see how bad the problem really is. Caked-on dust not only clogs up your intake fans, but can also clog up your lung passages.

Indoor air quality has become a more important issue for all of society. Secondhand smoke is just one example. Many workers must smoke cigarettes at least 100 feet away from buildings so that air intake vents will not spread the fumes to all the staff.

Industrial Bag Filters

The concept behind all bag filters is the same as your vacuum cleaner bag filter. You take a disposable unit and collect all of the waste products from your processes therein. These filters can be used for solids, liquids or gases.

Durable industrial filters have different micron particulate mesh size holes that control what can pass through it and what is trapped therein. You can purchase a bag filter for each of your machines. You also have the option of buying a complete filter machine through which you pass your solid, liquid or air flow.

Clean or Toss the Bag Filter

The genius of bag filters is that you can easily remove them for cleaning. Some machines and equipment can be tough to disassemble, lift or maneuver about. Handy, industrial filters will also reduce your assembly line down-time.

Create a clean, hygienic working environment for all of your employees by purchasing the filters that can be easily cleaned. You can keep machine down-time due to cleaning to a minimum; you can keep employee down-time due to sickness to a minimum. Trust the industrial filter that keeps your workers operating at optimal efficiency.
