The VFI is based on the principle of vortex shedding behind a bluff body

Pipework connection is via PN 6/10 DIN flanges (EN 1092-2 and ISO 7005-2)

Spring material is Alloy C-4 (NiMo16CrTi

even for high-viscosity or degassing liquids

The R-version is designed to be highly efficient against corrosive liquids

cri 1s 3 a fgj a v hqqv 92899962 The VFI is based onVertical, multistage centrifugal pump with inlet and outlet ports on same the level (inline). Pump materials in contact with the liquid are in stainless steel. Power transmission is via a rigid split coupling. Pipe connection is via combined DIN ANSI JIS flanges. The pump is fitted with a 1 phase, fan cooled asynchronous motor.
