  • 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 ...

  • Overview of Sanitary Pump

    Sanitary pumps involve the delivery of all human contact products such as pharmaceuticals, dairy products, beverages, food products, cosmetics, food additives, fine chemicals and the like. There are four types of sanitary, centrifugal, volumetric, jet and air pumps. Centrifugal pumps apply centrifugal force to create velocity, using a rotating wheel to increase speed and push fluid through the ...

  • Centrifuge Technology in Drilling Fluid Recycling

    Drilling fluid additives and the water that contains them are an essential part and expense of successfully completing a horizontal directional drilling (HDD) installation, and the longer the bore and larger the product being installed, the more drilling fluids cost. Therefore, it makes economic sense to recycle drilling fluids by removing cuttings and recirculating the cleaned ...

  • VFD for pumping systems

    Pumping systems account for nearly 20% of the world's electrical energy usage. In some process plants, the VFD for pumps and fans together account for between 50% and 80% of the total electricity used. Very rarely have I come across pumps operating with fully open discharge valves. The same is the case for fans with dampers. ...

  • 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 ...

  • 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 ...

  • Pumps for energy-efficient water and wastewater treatment

    Multiphase pumps are unique products with outstanding features compared to conventional centrifugal pumps. The approach consists of using the pumps not only for transport of liquids but also for partial gas supply and as dynamic mixer for gas enrichment. Therefore this novel pump conception barely has something in common with a standard pump. Even the mode of ...

  • Meat Processor Wastewater Pump System

    RPC determined that the DAF was best suited by replacing the existing transfer pump system with a new AISI 316 stainless steel Rogue MAX TRS TM-200S.The new trash pumps replaced the existing pump directly with twin MAX TRS TM-200S units instead of the single pump in place previously. Twin pumps offered the advantage of reduced individual cycle duty as well as an in place redundant ...

  • Peristaltic pumps for moving filtration water

    The Eversburg sewage treatment plant is designed to serve 250,000 population equivalents and is one of three plants operated by the city of Osnabrück in northern Germany. But in 2005, its actual load was closer to 309,000 population equivalents (COD 80 mg/l), pushing the nitrogen input level above the plant's capabilities. To deal with this situation, engineer Peter Sikora organized a team ...

  • Horsepower on the pump curve

    Now that the head capacity relationship along the X and Y axes of the pump curve has been established in Part 1 of this series, the pump curve can be used to determine the amount of horsepower required to meet the head and capacity requirements for the job. Horsepower is a unit of power equal to 550 foot pounds per second or 746 watts. Water horsepower is the minimum power ...

  • 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 ...

  • Pumping at Subzero Temperatures

    Pumping of cryogenic (low-temperature) products is important for many applications, especially in the field of liquefied natural gas (LNG). The Sulzer J-unit is a special sealing system for cryogenic pumps. It was invented more than 60 years ago. The evolution of the J-unit design since then has been impressive and has now resulted in a recently filed patent application by Sulzer. ...

  • Large Diameter Impellers Make Trash Pumps More Versatile

    The introduction of these impellers allow for a higher range of discharge pressure. Pumps are available in many types—diaphragm, positive displacement and progressive cavity—but the most common is a centrifugal pump. Centrifugal pumps have an impeller that spins, transferring energy to the fluid by centrifugal force and directing the water to the discharge point within the ...
