The METTA MF series comprises end-suction centrifugal pumps engineered for fire protection systems, fully compliant with the EN 12845 and EN 12259-12 standards.

Built for reliability where it matters most, each pump features a robust back pull-out design, facilitating maintenance by allowing complete disassembly of the drive components and impeller without disconnecting or repositioning the motor, pump housing, or connected piping.

With 38 models covering flow rates from 3 to 480 m³/h and total head up to 120 m, the MF range offers the flexibility to meet the hydraulic requirements of virtually any fire protection project, from small residential buildings to large industrial facilities.

Wetted components are manufactured from corrosion-resistant materials — stainless steel AISI 316 impeller and shaft for smaller models, bronze for larger — ensuring long service life even under demanding conditions. The standardized mechanical seal (ISO 3069) and wear ring in bronze further contribute to low maintenance costs over the pump’s lifetime.

The MF series is the dependable choice for engineers and contractors who need certified performance, proven materials, and the confidence of a fully supported product from specification through to after-sales service.
