8 SEG Product description Operating conditions Pumped liquids The pumps are designed for intermittent operation (S3). When completely submerged, the pumps can also operate continuously (S1). pH value: 4-10. Liquid temperature: 32-104 °F (0-40 °C). When pumping liquids with a density and/or a kinematic viscosity higher than that of water, use motors with correspondingly higher outputs. For short periods (maximum 3 minutes), temperatures up to 140 °F (60 °C) are permissible (non-Ex versions only).
8 SEG Product description Approvals The standard versions of SEG 60 Hz pumps have been approved by CSA, and the explosion-proof versions hold an FM type examination certificate. Approval standards These pumps are CSA approved according to UL778 and C22.2 no. 108, no. 0.4, no. 30, no. 145 and no. 60529. The pumps are FM approved according to FM 3600, FM 3615 and FM 3650 and ANSI/IEC 60529.
