FELUWA Pumpen GmbH products

The tailored solution for high pressure ranges up to 350 bar. FELUWA MULTISAFE® double hose-diaphragm pumps allow for reliable and low-wear handling of abrasive, aggressive and challenging media. Thanks to the linear flow path through the hose-diaphragm and the valves, the conveyed fluid will neither come in contact with the pump head nor the hydraulic area.

The compact multi-purpose solution for low pressure ranges up to 16 bar. The EcoTrans MULTISAFE® pumps represent the latest generation of hydraulically activated double hose-diaphragm pumps.

The check valves are considered as the only actual wearing part. Due to their cassette design the valves are easily replaceable. Larger valves are equipped with a swivelling device. Calculation of flow geometry by means of latest CFD methods. Patented FELUWA Quick Change System. Individual material selection guarantees safety and maximum service life.

Steady and reliable pump operation is guaranteed by efficient, fully automatic, low-wear hydro-mechanical control systems. Individually for each pump head. Consistent, simple, safe. Hydro-mechanical leakage compensation control precisely secures the volume of the hydraulic fluid in the working chamber. Pressure relief valve protects the pump against overload caused by system excess pressure. By-pass capacity regulating unit for regulation of the volume flow at short notice.

Flow fluctuations are avoided by means of different types of pulsation dampeners: PULSORBER 900 with roller diaphragm accumulator, hose-diaphragm pulsation dampener or traditional pulsation dampeners (pressure air vessel) with air or gas cushion. Individual, tailored solutions.

Tailored instrumentation and pump control systems permanently monitor the condition of elements essential for operation. They ensure reliable pump control and efficient transmission to higher ranking control systems.

Efficient reduction of the residual pulsation by means of electronic crank shaft coupling helps optimising phase shifting of the pumps. Not only the pumps are protected, but all downstream equipment accordingly.

DownFlow Technology, which means flow from the top to the bottom, allows for reliable pumping of heterogeneous mixtures and media with high settling speed to avoid disadvantageous sedimentation. Safety for your challenging pumping application. Reliability thanks to special, tailored check valves. Stability for your process.
