Frequently Asked Questions

Self-priming height decreases with altitude due to lower atmospheric pressure. Rule of thumb: approximately 1m reduction per 1000m elevation gain. At 3000m, expect roughly 3m less priming lift than at sea level. Consult pump curve for exact values.

For strongly oxidizing media:
1) Select PVDF or fluoropolymer materials (not standard plastics),
2) Use EPDM or Viton elastomers as appropriate,
3) Ensure no metallic wetted parts that could corrode,
4) Consider magnetic drive to prevent seal failure,
5) Verify temperature limits.

Vertical pumps ensure drainage efficiency in high-rise buildings by: being submerged directly in sumps (no priming issues), handling variable water levels effectively, providing consistent pressure across building heights, and saving valuable floor space in mechanical rooms.

Smooth transition is achieved by: using variable frequency drives (VFD) for gradual speed changes, installing dampers with controlled actuation, implementing pressure sensors with feedback control, and ensuring the fan operates within its stable curve range during transitions.

Maintain stable filtration accuracy by: using consistent filter media rating, proper flow rate control (not exceeding design velocity), regular backwashing or cleaning before media becomes blinded, uniform flow distribution across filter surface, and monitoring pressure differential.

The cooling system circulates process fluid through the containment can gap to dissipate heat generated by magnetic eddy currents and bearing friction. It prevents overheating of magnets and bearings, ensures lubrication of internal bearings, and prevents demagnetization at high temperatures.
