FELUWA MULTISAFE® double hose-diaphragm pumps
for abrasive, aggressive and toxic media
 

EcoTrans MULTISAFE® Pump

The universal solution for low pressures up to 16 bar

 

The EcoTrans MULTISAFE® product range represents the latest generation of hydraulically-activated double hose-diaphragm pumps. This type of pump is particularly utilized for critical applications, mechanically abrasive and chemically aggressive liquids as well as highly viscous media (even with particles) of different consistencies. Depending on the respective medium, the dry-matter content can be up to 80 %.

Characteristics

  • Area of application
    The EcoTrans MULTISAFE® pump is used for the transport of abrasive, aggressive, highly viscous or toxic fluids and, especially, for metering and feeding of filter presses, reactors and spray driers. 

  • Flow range
    The EcoTrans MULTISAFE® is designed for a flow rate of 2 to 20 m³/h and achieves operating pressures of up to 16 bar, thus providing a genuine alternative to the pumps that hitherto have been used in low-pressure applications.

  • Innovative
    The EcoTrans series of pumps already complies with the requirements for „Industry 4.0“. It offers operators optimum integration in common process control systems and early fault detection that is unique in this class.

  • Reliable
    Irrespective of pressure and viscosity, the pump ensures continuous low-wear conveyance with low pulsation.

  • Flexible
    The flow can be controlled without the use of an additional frequency converter owing to the bypass capacity regulating unit in the hydraulic system.

  • Different sizes to suit the available space
    The new generation of MULTISAFE® pumps with their space and weight-saving design is available in 3 sizes (figures 1-3).

  • Durable
    Pumps designed with the tried-and-tested FELUWA MULTISAFE® technology are ideally suited for conveying critical fluids of different consistencies (also with particles).
    A number of different materials is available for fluid-wetted parts.

  • Safe
    The pressure relief valve fitted within the hydraulic system ensures that any overload situation during operation is reliably prevented.

  • Ready for use
    The delivery period for the EcoTrans MULTISAFE® pump is only 2 weeks, making it readily available for projects at short notice.

Advantages

  • Tried-and-tested MULTISAFE® technology
    Only the valves, pipes and hose-diaphragms come into direct contact with the medium. This means that the pump casing does not require expensive special materials such as duplex stainless steel. In view of the fact that the piston seals only come into contact with the hydraulic liquid, they have an extended service life. This reduces maintenance costs and significantly increases the availability of the pump.
     
  • Efficient
    FELUWA hose-diaphragm piston pumps achieve a hydraulic efficiency of up to 98 %, the highest of all pump technologies. The EcoTrans MULTISAFE® combines high efficiency with low energy consumption.

  • Maximum availability and low maintenance costs
    The high degree of volumetric efficiency and low energy consumption as well as the long service life of the wear parts reduce the operating and maintenance costs to a minimum. With a service life of more than 20,000 operating hours, the hose-diaphragms are not a typical wear part. In consequence, the cost of spare parts only amounts to approx. 2 % of the purchase cost (CAPEX) per year (figures 4+5). 
     
  • Safe and reliable process
    The hermetically sealed double hose-diaphragm system guarantees safe and reliable transport of critical and environmentally hazardous fluids. Two hose-diaphragms, which are arranged one inside the other, are fitted in the pump head and ensure that the medium is safely contained and efficiently conducted whilst the periphery remains hermetically separated. This means that any leakage to the outside or contamination of the medium is precluded (fig. 6).

  • Frequency converter
    The requirements for modern pump systems are continually changing. It is therefore recommended to equip the pump with a tailor-made frequency converter in order to be able to vary the volume flow within a large range while maintaining high efficiency.

  • Hose-diaphragm condition monitoring
    The FELUWA Hose-Diaphragm Guard (HDG) permanently monitors the inner and outer hose-diaphragm and detects leakages early. Even with leakages at one hose-diaphragm operation can be maintained until the next planned service and contamination of the conveyed medium or contact to the hydraulics can be safely prevented (fig. 6).

Options

  • FELUWA DownFlow Technology (DFT)
    For the purpose of transporting fluids containing solids with a tendency to sedimentation, FELUWA literally turns the traditional pumping principle upside down. In this case, the fluid is transported from the top downwards, thus using gravity to aid transport. This is a reliable method for avoiding sedimentation and any associated failure of the entire pump (fig. 7).

  • In-built piston compressor
    In order to reduce fluctuations in terms of pressure and flow, the EcoTrans MULTISAFE® pump has been designed as a modular system allowing the piston rod – which is guided on both sides – to be extended as a piston compressor. This reduces fluctuations in pressure to a minimum and ensures optimum damping, resulting in significantly more even and efficient transport with low-wear characteristics (fig. 8).

  • Crankshaft coupling
    Pulsation in the pipe system is efficiently prevented by coupling the crankshafts of several pumps. These pumps supplying the same pipe system can also be located apart from each other.

  • Safety with all operating conditions
    For us, safety has top priority; the pumps will not be damaged, even as a result of operating mistakes or in the case of extreme operating conditions. With the FELUWA Suction Guard (SG) we provide maximum protection of man and machine – not only in the case of excessive inlet pressure, but also in the case of a blocked suction pipe.
