Minerco - Model ZA Series -Chemical Process Pump

• Advanced Design: Complies with ANSIB731M standard, incorporating modern pump manufacturing advancements.
• Versatility: Interchangeable parts reduce spare parts management costs.
• Reliability: Ensures minimal downtime and consistent performance.
• Economy: Lowers overall operating costs.

Sealing Technology:

• Static Seals: Primarily O-rings, fluoroelastomers, or PTFE in special cases.
• Dynamic Seals: Mechanical seals (single or double end faces, balanced or unbalanced types).
  • Balanced seals for high-pressure sealing.
  • Double-end seals for high-temperature, viscous, or hazardous media.
  • Requires injection of isolation fluid into the sealed cavity.

Construction Features:

• Seal Cavity: Inverted cone design with flow guiding block to minimize impurities` impact on seals.
• Impeller: Back-open structure for easy gap adjustment with the pump cover.
• Lubrication: Thin-oil lubrication system with splashing discs for enhanced cooling and lubrication effectiveness; constant oil cup ensures sufficient lubrication.
• Maintenance: Axial adjustment mechanism allows external adjustment of impeller-pump cover gap without pump removal, simplifying maintenance.
