Advanced engineering meets industrial resilience—discover how innovative pump technology is solving critical challenges in the mining, power, and chemical industries.
The pump technology behind FELUWA’s growth is rooted in traditional diaphragm and diaphragm piston pumps. The company launched the hose-diaphragm piston pump – a hermetically sealed, leak-free, oscillating positive displacement pump – 50 years ago. This innovation has established benchmarks across diverse industries globally.
In 2002, FELUWA introduced the patented MULTISAFE® double hose-diaphragm pump, combining the efficiency of a piston diaphragm pump with technological advancements.
Functionality of the MULTISAFE double hose-diaphragm pump
The crank drive converts the drive motor’s rotary motion into a reciprocating piston movement. This movement is transferred to the double hose-diaphragm via a non-compressible fluid, creating the pumping effect in the pump head.
The hose diaphragm moves in a controlled manner with each pump stroke, ensuring a linear flow without turbulence. This has several benefits, including reducing the risk of sedimentation and mechanical stress while extending hose-diaphragms’ service life.
Due to their design principle, FELUWA MULTISAFE pumps are perfect for demanding pressure levels and large flow capacities. They operate at discharge pressures of up to 350 bar and handle flow rates of up to 1000 cubic metres per hour.
How FELUWA is providing better diaphragm pumps
The MULTISAFE double hose diaphragms inside each pump head create a redundant hermetic seal, effectively isolating the processed media from both the external environment and the hydraulic drive. This design enhances operational safety while safeguarding internal components. With fewer wetted parts than conventional pumps, the medium remains separate from the pump head and hydraulic section. Depending on application requirements and media properties, carefully chosen materials minimize chemical erosion and wear.
Reliable performance with abrasive and aggressive media
The MULTISAFE pump operates without dynamic seals, protecting moving components from abrasive and aggressive media. This design increases durability and operational reliability. Additionally, material configurations can be adapted to changing process requirements. In Australia, FELUWA pumps are widely used in the mining and minerals sector for demanding applications such as tailings disposal, ore concentrate transport, autoclave and leaching processes, filter press feeding and mine dewatering.
Their robust design ensures long-term reliability, even in the harshest operating conditions.
FELUWA pumps are also suited to other industries and challenging applications that include reactor feeding, spray dryer feeding, fly and bottom ash disposal from coal-fired power plants, bauxite and red mud transfer, coal gasification feeding, the chemical industry – many, varied applications.
Improved availability with monitoring and diagnostics
All MULTISAFE pumps are equipped with advanced monitoring and diagnostic systems that continuously track the condition of hose diaphragms and check valves. These systems provide timely information on wear and maintenance needs. If one hose diaphragm fails, the second ensures continued safe operation. A precision leakage compensation valve maintains hydraulic fluid balance, providing reliable performance. These features facilitate planned maintenance and integration into existing operational schedules.
