Maximum head and maximum flow are separate limits; they are not reached at the same time. Use the performance curve in the catalogue to confirm your duty point.
Where two weights are given, they are single phase / three phase, excluding cable.

SF Series features
Tell us the liquid, its strength and temperature, and we will confirm the right pump and material.
Sealed cable entry
An epoxy resin cable base stops moisture getting into the motor through the core wires.
Automatic motor protection
An auto-cut thermal switch cuts power on a power surge, locked rotor, phase failure or overload, then restarts the motor once it has cooled.
High-efficiency dry motor
Varnish-insulated stator coils for good insulation, efficiency and durability.
Double mechanical seals
Abrasion-resistant silicon carbide seals run in an oil housing, independent of the pumped liquid.
Two impeller options
SFU models have a vortex (U-type) impeller; SFP models have an open (P-type) impeller.
304 or 316 stainless steel
Built in 304 or 316 stainless steel, with Viton O-rings for corrosive liquids.
