Consider Pressure Drop When Sizing Injection Pumps
Chemical injection pumps charged with injecting fluids into a pipe must be properly sized in order to overcome the pressure in the pipe.
Servos Can Help Prevent Machines from Falling Down
Eccentricity machined into rolls can cause wobble—defined as the angular deviation of the axis of rotation over one revolution.
Pumping in Parallel Is Not Always Simple
Inadequate flow rate often plagues two-pump systems, particularly in plants that are more than 10 years old.
Selecting the Right Vacuum Pump for the Job
Laboratory managers specifying vacuum pumps have much to consider when evaluating the four basic types of pumps.
A Flush Plan May Help Optimize Seal Life
Circulating fluid to or from the seal chamber will maintain proper lubrication, pressure, temperature and solids management.
Refinery Installs Compact Plunger Pumps
The pumps use an in-line gearbox and B5-flange mounted motor.
Impact of the Oil Crisis on the Centrifugal Pump Market
The global market for centrifugal pumps is expected to grow at a compound annual growth rate of 3.8% from 2014 to 2019, from $33.2 billion in 2014 to over $40 billion in 2019, IHS says.
Cutting Compressed Air Costs: Tips and Technologies
The savings can range from thousands of dollars to in excess of $100,000 a year for a single plant.
Fundamentals of Cooling Tower Heat Transfer – Part 1
The first of a three-part series that examines the basics of cooling tower heat transfer and outlines methods to keep towers clean.
Natural Gas for Export: Process Fundamentals for Engineers, Part 1
This article, the first of three, outlines a number of fundamental concepts regarding natural gas and liquefaction processes.
Heat Exchangers and Their Applications
Heat exchangers transfer heat energy from one fluid to another in order to control the temperature of a system or substance.
Fuel Dispensing Equipment & Operation
Fuel dispensing equipment dispenses and monitors liquid or gaseous fuel. Fuel dispensers are used to pump liquid fuels such as gasoline, diesel fuel, oil, or kerosene into a vehicle, aircraft, storage tank or portable container.
ISO Publishes Pump System Standard
The new ISO/ASME standard 14414, which sets the requirements for conducting and reporting the results of a pumping system energy assessment, considers the entire pumping systems, from energy inputs to the work performed as the result of these inputs.
Industrial Pump Derived from Bird Wing Motion
Birds manipulate airflow each time they flap their wings, pushing air in one direction and moving themselves in another. Two New York University researchers, Benjamin Thiria and Jun Zhang, have created a pump that moves fluid using vibration similar to a bird's motion.
Is a Metal-seated Ball Valve for You?
Metal-seated ball valves were first introduced to the market to address many of the shortcomings of their soft-seat counterparts. The ability to withstand severe service conditions such as high temperatures, cryogenic conditions, abrasive mediums, slurries, and flow control make them ideal candidates for use in the oil refinery, petrochemical, mining, pulp and paper, iron and steel mill, electric power generation and water treatment industries.
Technology Innovations Turn Wastewater Plants Into Energy Producers
Their main business may be cleaning up water for drinking and other human purposes. But today, some water and wastewater treatment facilities are also turning themselves into small-scale power plants.
Proposed ASTM Biodegradable Hydraulic Fluid Standard
A proposed new ASTM International standard, WK31234, Specification for Biodegradable, Low Aquatic Toxicity Hydraulic Fluids, intends to make it easier to ensure that proper hydraulic fluids are being used at environmentally sensitive job sites.
Evaluating Variable Speed Motors for Centrifugal Pump Applications
The cost of electrical power to keep a 200 HP pump motor running continuously now exceeds $100,000 a year in most areas of the United States, and more in other countries where the cost of electricity is higher.
Solar-Powered Desalination for Off-Grid Villages
Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60% of India is underlain by salty water, and much of that area is not served by an electric grid that could run conventional reverse-osmosis desalination plants. Analysis by MIT researchers shows that
