  • 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 ...

  • Submersible Pumps - The Airlift Principle

    The Air lift principle has been around for many years. In fact it was first conceived in 1797 by the German engineer Carl Emanuel Löscher and is one of the most simple and basic ways to pump water and other fluids. Not only is the principle simple, there is not much to go wrong. Airlift in its simplest form had its limitations, but recent developments have enabled far more ...

  • The Versatility of Hydraulic Submersible Pumps

    Hydraulic submersible pumps offer flexibility and performance When determining a pump for an application, there are a number of factors to consider. Hydraulic submersible pumps are an option and give the added benefit of run dry capability, especially when electric powered pumps are of concern due to potential electrical hazards or other reasons, or diesel driven centrifugal pumps ...

  • Submersible Pumps vs. Self-Priming Centrifugal Pumps

    When selecting a centrifugal pump for bypass work, the first consideration should be NPSHR by the pump. Neglecting the NPSHR of the pump is the single most common mistake when choosing a self-priming or priming assisted pump. A function of the pump design requires part of the 33.9 ft (14.7 in.) available as further defined in this article. A centrifugal, and in a way submersibles, require part ...

  • Canada pump and power utilizes hydraulic submersible pumps in unique applications

    Abrasive slurry, temperature swings of more than 100 degrees Fahrenheit, remote locations…any of these things would test a pump system. Canada Pump and Power’s hydraulic pump platforms face all three obstacles to transfer solids out of waste ponds. In service for more than two years, CPP’s Hydraulic Tiller Dredge utilizes a Cornell hydraulic submersible 6NNT pump married with a ...

  • End the waste of wastewater pumping

    An innovative and sustainable system that is patented and proven with 1,000s in use will save municipal ratepayers, taxpayers, and maintenance personel great amounts. I have been involved in the pump business that goes back almost 40 years. I have the enviable position to be able to replace the “old school” municipal submersible pump systems (that I sold) and are now outdated or ...


  • Avoiding Pump Problems

    As with any pump system, there are some basic components involved — a driver, the impeller/pump and the transmission. The basic difference is that instead of a flexible coupling or gear train, the transmission is a hydraulic system. The hydraulic system is composed of a hydraulic pump, hydraulic motor, supply tank, filtration method, cooling method and transfer ...

  • Effects of Slurry pump expeller

    Expeller not only with sealing effect, but also can serve to reduce the axial force. The axial force in the slurry pump is mainly caused by the liquid pressure acting on the impeller and the rotating part of the composition of gravity. So it is easy to know, in the same identical performance parameters, slurry pump axial force is stronger ...


  • 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 ...

  • Pumps for the Booming FPSO Sector

    In the last few years, several new offshore oil fields have been discovered. The current findings from Petrobras and other companies in the pre-salt province, located in the Brazilian continental shelf, suggest reserves of over 50 billion barrels of oil. Extracting the pre-salt oil is challenging and done increasingly with floating production storage and offloading units (FPSOs). Sulzer offers a ...
