Operating range of the shaft seal

The operating range of the shaft seal depends on operating pressure, pump type, type of shaft seal and liquid temperature. The range shown in fig. 5 applies to clean water and water with anti-freeze liquids. If the operating range is exceeded, the life of the shaft seal may be reduced.

Operating Conditions

Delivery liquids : non-viscous, non-flammable/explosive, without neither solid nor fiber particles, and should not cause physical nor chemical damage to the pump. For viscosity larger than water, use pumps with a higher output if necessary. Whether a pump is suitable for a certain liquid depends factors such as the liquid’s chlorine content, PH value, temperature and composition, among other factors. Liquids temperature: -20°C to 120°C Environmental Temperature: Maximum 40° At environmental temperatures over 40°C or altitudes over 1000m above sea level, motor heat dissipation will be reduced due to reduced air density thus reducing heat dissipation, and cause adecrease in power output. In those situations, higher rated pump is necessary. Minimum suction pipe pressure: the suction pressure should be calculated and checked if any of these conditions exist: High liquid temperature Flow significantly larger than rated maximum Liquid requires long suction distance The suction pipe is long Liquid entry conditions are bad
