Grundfos SP pump is built with octagonal bearings with sand flush channels that minimise wear. As wear of the pump is
inevitable, the pump design allows for easy replacement of all internal wear parts (bearings, impeller, wear rings
and seal rings) to maintain high performance and a long lifetime.
The suction interconnector is fitted with a strainer to prevent large particles from entering the pump. The suction
interconnector is designed to comply with NEMA standards for motor mounting/dimensions.
Motor
The winding wire is made of pure electrolytic cobber insulated by extruded PVC insulation with high dielectric
strength properties allowing direct contact between the motor fluid and winding wire. This ensures the best
possible cooling of the winding wire.
The shaft seal faces are SiC/SiC. The material combination gives good performance when abrasive particles
(sand) is present. Together with the shaft seal housing, the sand shield forms a labyrinth seal, which during normal operating conditions prevents penetration of sand particles into the shaft seal. This shaft seal is drinking water
approved.
The motor can be fitted with a Pt100 or Pt1000 sensor that together with a control unit ensures that the maximum
operating temperature conditions are not exceeded.
