  • Measuring Pressure and Vacuum Correctly

    Pumps and systems are installed, started, operated, and many times, forgotten. When a problem arises, it’s recommended to install a discharge pressure gauge and suction vacuum gauge on the system. These gauges should be installed near the suction inlet and discharge outlet of the pump. These gauges are usually installed properly, recorded, and along with a pump speed measurement can be ...

  • How can I finely control the vacuum applied by my vacuum pump or system?

    Some vacuum pumps or built in vacuum systems do not allow fine control over the vacuum applied. For rough work like vacuum filtration this is not always needed, but for more sensitive work, for example when using a rotary evaporator, application of the correct vacuum level is essential to smooth operation. The new ...

  • What is the difference between Rotary Vane and Diaphragm vacuum pumps?

    Most laboratories will have a vacuum pump. They are widely used across labs of all disciplines for a range of tasks from basic filtrations or evacuating a desiccator right up to use with large equipment such as vacuum ovens or rotary evaporators. The two most common types are rotary vane or diaphragm pumps – but ...

  • Vacuuming Wood Dust Can be Hazardous

    It’s well known that wood dust is highly combustible, but the practice of removing it with vacuum trucks can also be dangerous, because of the potential buildup of static electricity. WorkSafeBC has issued a bulletin stating that “static electricity discharges can ignite wood dust and therefore must be eliminated or adequately controlled during vacuuming.” When wood dust or ...

  • Vacuum systems for tall-oil applications

    Tall oil is a viscous oily liquid and considered one of the most important by-products of wood pulp manufacturing. Through a fractioning process crude tall oil can be turned into valuable fatty and resin acids. Vacuums play a key role in this procedure. An application in Finland currently proves that technology from Hanover-based Körting is ideally suited for this purpose. ...

  • Desubmerge Your Submersible Pump

    A few decades ago, well, definitely not more than four, a contractor was introduced to electric powered submersible pumps. The crew’s first reaction was, “What! You’re going to throw that electric motor in the water? You’ve got to be crazy!” After a few weeks of getting comfortable with the subs, the whole crew was handling them like ...

  • Sioux Falls, Verder Pumps

    The Sioux Falls Water Purification Plant in South Dakota USA, had always relied on gravity to feed slaked lime slurry to their softening basins. In 2009, the staff decided to give gravity a helping hand by trialing a pump to move the slurry more effectively. Lime slurry is a dense product to transfer with a high solid content of up to 35%. Due to the slurry’s abrasive nature which causes ...

  • Pump Performance Checklist

    Keeping your pump in shape will help reduce costs and boost profits! Cut fuel consumption, reduce replacement parts costs and minimize pumping time on every job! A PUMP THAT LETS YOU DOWN when you need it most causes obvious losses of time and money. Not so obvious, but every bit as costly, are losses you can incur with pumps that operate at less-than-peak efficiency. A pump ...

  • Understanding Pump Cavitation

    Cavitation is a major problem in the chemical industry because it affects a basic tool, the centrifugal pump. A sudden increase in the velocity of the pumped liquid reduces the inlet pressure, sometimes below the vapor pressure.The result is formation of gas and bubbles. Detecting the signs of cavitation, and correctly identifying and understanding the type of cavitation present, can help an ...

  • The Alternative to Pump and Treat

    Sometimes, an important technological advance begins with a small step – back! Such is the case with remediation of hydrocarbons from groundwater utilizing existing recovery and monitoring wells. For the past few years, state government has based decisions on the amount of clean up that they require by the risk posed to the environment. Risk Based Corrective Action, commonly called 'Rebecca' ...
