SPECIFICATIONS

PUMP

– from -10°C to +90°C for S and N versions with coupling.

– from -10°C a +60°C for close-coupled E versions.

Maximum ambient temperature: +40°C.
Mechanical seal Mechanical seal in Ceramic/ Carbon/FPM for the close-coupled E version and in Silicon Carbide/ Carbon/FPM for S and N versions with coupling. For SVI 33-46-66-92 models, mechanical seal can be replaced without removing the motor from the pump.
Tank coupling flange in compliance with EN 12157 (ex DIN 5440) for SVI 2-4 models.
Standard installation in vertical position; horizontal installation on request.
These pumps can handle clean liquids free of abrasive substances or fibres, with kinematic viscosity up to 37mm2 /sec, with suitably sized motor.
Minimum level of suction liquid: 25 mm for SVI 2-4-8-16 models and 80 mm for SVI 33-46-66-92.
Base in the suction side with filter in order to avoid damages due to solids entrance.
Tested in compliance with ISO 9906 Annex A.
Direction of rotation: clockwise look- ing at the pump from the top down (marked with an arrow on the adapter and on the coupling).
Longer pump columns (from coupling flange to suction base) are available on request. Possible variants are indicated in each model’s dimensions table.
