FLYGT PROPELLER PUMPS

     

    Flygt self-cleaning N-technology revolutionized wastewater handling in 1997. Over 300, 000 installations later, it has become the global
    benchmark for non-clogging performance and sustained high efficiency. Flygt propeller pumps offer N-technology for reliable pumping
    of high volumes at low heads.

     



    How it works
    N-technology reduces the risk of clogging in three ways:

    1. The leading edge of the propeller blades has a radical swept-back design.
    This ensures that plastic bags, fibers, clothing and other material slide
    down the leading edge of the propeller blades out towards the pump housing.

    2. Here, the material is fed into what we call the relief groove: a track cut into
    the inner-face of the pump housing. The relief groove forces the material
    through and out the pump.

    3. In conventional propeller pumps stringy material can get caught on the guide-vanes. But with N-technology, the special design of the guide-vanes creates
    local turbulence around any accumulated material. This eases it off the vanes, after which it gets expelled from the pump housing.

    Together, these features add up to high reliability and low operational costs.


    Lower energy costs, fewer stoppages
    With increased resistance to clogging, Flygt propeller pumps will give you high reliability, together with reduced risk of motor overload and unplanned stoppages. Reduced clogging also provides sustained factory-new pump efficiency, year after year.

    The name Flygt has been synonymous with innovation from the early 1920s. In 1947, Sixten Englesson, the company’s head
    engineer, developed the world's first submersible drainage pump. It was an invention that came to revolutionize the mining and
    construction industries. This has been followed by a long list of industry firsts – below, a small selection.




    Anything from 100 to 7,000 liters per second
    Flygt propeller pumps are designed for pumping large volumes at low heads. Because they are optimized to pump within this range,
    they provide a cost-effective alternative to centrifugal wastewater pumps.


    Pumping anything from 100 to 7,000 liters per second, our portfolio of pumps gives you a wide range from which to select.

    Robust and reliable
    Every Flygt propeller pump is tested before leaving our factory to
    ensure high performance and quality. Like all Flygt products, Flygt
    propeller pumps deliver solid cost-effective performance that has
    been proven for more than 40 years in applications such as:


    • Storm-water
    • Wastewater treatment
    plant effluent
    • Return activated sludge
    • Water intakes


    • Flood control
    • Irrigation
    • Amusement park attractions
    • Surf riders
    • Aquaculture

    PL pumps – low head, very high flow
    With their huge capacity and low power consumption Flygt PL pumps are ideal for moving large volumes at low heads.
    N-technology reduces the risk of fibrous material building up on the pumps, resulting in sustained efficiency over the long-term.

    Class H (180°C/355°F) insulated motor – greater reliability
    All motors are fully submersible (IP68) to a depth of at least 20 meters. Pumps are available in explosion-proof versions for use in hazardous environments. Long-life bearings provide extended operational lifetime.

    Unique seals – extra safety
    Flygt mechanical seal systems minimize shaft overhang, while maximizing cooling and lubrication. Two pairs of mechanical shaft seals work independently for double safety. The Flygt Active Seal™ system offers increased seal reliability and zero leakage into the motor, therefore reducing the risk of bearing and stator failure.
    An extra level of safety is provided by a double-grommet cable sealing.

    Sensors – pump protection
    Thermal sensors in the stator windings prevent overheating. Analogue Pt100
    sensors monitor stator and bearing temperatures. Leakage sensor(s) alarms you
    to liquid intrusion through cable or seal. A vibration sensor warns against abnormal conditions.

    Reliable and efficient hydraulics
    N-technology ensures maximum reliability and sustained high efficiency.
    The suction of the pump is sealed with a replaceable rubber seal on the pump seat. Pump performance includes all losses (including pump column losses) up to at least 500 mm above the top of the motor.

    Swept-back propeller reduces clogging
    With the help of computational fluid dynamics, our engineers have developed a sweptback leading edge design that reduces the risk of plastic and fibrous materials from building up on the propeller.

    Shaft shield – limits shaft clogging
    To reduce the risk of plastic and rags wrapping
    themselves around the propeller shaft, Flygt PP
    pumps feature a shaft shield. Consisting of a collar
    around the propeller and matching design around the
    oil housing, the shield creates local flow patterns
    which help keep fibers away from the shaft.

    Sensors – pump protection
    Thermal sensors in the stator windings prevent overheating. Analogue Pt100 sensors monitor stator and bearing temperatures. Leakage sensor(s) alarms you to liquid
    intrusion through cable or seal. A vibration sensor warns
