Frequently Asked Questions

Structural considerations include: impeller design matched to flow velocity range, volute geometry optimized for the design point, suction passage sizing to prevent excessive inlet velocity and cavitation, and discharge nozzle sizing to control exit velocity within pipe system limits.

High humidity can cause: moisture condensation in motor windings reducing insulation life, corrosion of metal components if not properly coated, and slight changes in air density affecting performance. In extremely dry conditions, static electricity buildup may be a concern.

Installation foundation must: provide rigid, level support to prevent vibration, handle the full weight of pump plus liquid column, be corrosion-resistant if in wet environment, allow proper anchoring of the mounting plate, and maintain perpendicular alignment of the pump shaft.

At high temperatures, magnetic pumps experience: reduced magnetic torque (NdFeB magnets lose strength above 80-120°C), increased eddy current losses in the containment can, accelerated bearing wear, and risk of permanent demagnetization if exceeding maximum temperature rating.

Typical self-priming height ranges from 3 to 6 meters at sea level, depending on pump model and design. High-performance self-priming pumps can achieve up to 8 meters. Actual performance decreases at higher altitudes.

Damaged isolation sleeve causes: immediate process fluid leakage into the magnet housing, corrosion of external magnets, loss of magnetic coupling efficiency, potential motor damage, and complete pump failure. The pump must be shut down immediately and the sleeve replaced.
