When engineers select a centrifugal pump for a chemical application, the most common mistake is treating specific gravity as a flow curve correction and stopping there. The flow-head curve of...
Fluimac Compass Series
Magnetic-Drive Centrifugal Pump
Zero-Leak Chemical Transfer Through Magnetic Coupling
The Fluimac Compass series separates the pumped liquid from the atmosphere with a sealed isolation shell — motion is transmitted through a high-power synchronous magnetic coupling instead of a shaft seal, so there is no dynamic seal to wear, leak, or replace. Casing and impeller are injection-moulded PP or PVDF for broad chemical compatibility, in five sizes spanning 3.5 to 35 m³/h and up to 25m head, for high-purity and highly corrosive liquids that are difficult to seal by conventional means.
No mechanical seal — rare-earth magnetic coupling eliminates the #1 pump failure point and the leakage/emissions risk that comes with it
PP and PVDF construction — injection-moulded casing and impeller resist highly corrosive liquids, with EPDM or VITON O-rings to match
RWP quick-change cartridge kit — bearing and shaft assembly swaps without special tools for fast, low-cost maintenance
Five sizes, 3.5–35 m³/h — CM04 through CM30 covering light-duty transfer up to full process-scale flow

All Compass Pumps
Semi-Opened Impeller
Fluimac Compass CM04
3.5 m³/h · 7.5m Head · 0.12 kW
Entry-size Compass for light-duty chemical transfer — the smallest mag-drive footprint in the range, still fully seal-less. Connections: 1″F / 1/2″M. Casing/impeller in PP or PVDF, EPDM or VITON O-rings.
Closed Impeller
Fluimac Compass CM06
7 m³/h · 8.5m Head · 0.25–0.37 kW
Closed-impeller step-up from CM04 for slightly higher flow with the same corrosion-resistant PP/PVDF construction. Connections: 1″F / 3/4″M. Casing/impeller in PP or PVDF, EPDM or VITON O-rings.
Closed Impeller
Fluimac Compass CM10
13 m³/h · 14m Head · 0.55–0.75 kW
Mid-range Compass sized for general process transfer duty, handling viscosity up to 200 cps. Connections: 1.5″F / 1″M. Casing/impeller in PP or PVDF, EPDM or VITON O-rings.
Closed Impeller
Fluimac Compass CM15
23.5 m³/h · 20m Head · 1.1–1.5 kW
Higher-capacity Compass for larger recirculation or transfer loops, up to specific gravity 1.8. Connections: 2″F / 1.25″M. Casing/impeller in PP or PVDF, EPDM or VITON O-rings.
Closed Impeller
Fluimac Compass CM30
35 m³/h · 24m Head · 2.2–3 kW
Largest Compass in the range — full process-scale flow and head while remaining completely seal-less. Connections: 2″F / 1.5″M. Casing/impeller in PP or PVDF, EPDM or VITON O-rings.
