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

Quality assurance at the test rig

In order to guarantee technical excellence to the customer, the custom-made pumps will only leave the FELUWA factory after they have proven effectiveness in an endurance test. All essential parameters like pressure, volume flow and temperature are verified and recorded.

The pumps, their drive technology, measuring and regulation technology as well as the complementary products are synchronized at the FELUWA test rig so the pumps are ready for use immediately after the commissioning on site by the FELUWA service engineers.

The implemented quality management system according to DIN EN ISO 9001:2015 ensures that a uniform and constant design and fabrication level is maintained.
