What materials are compatible with corrosive media for fluid conveyance parts?

For corrosive media (e.g., acidic/alkaline solutions), replace brass components with 316 stainless steel alternatives. EPDM hoses are recommended for water-based corrosive media; avoid chloroprene rubber in chloride-rich environments.

How often should core components like the spraying pump be inspected?

The spraying pump (11-3161-0827) should undergo full inspection every 500 operating hours, including impeller wear checks, seal integrity tests, and lubricant analysis. Replace the impeller if wear exceeds 0.5mm to prevent further damage.

Can I reuse spring washers during maintenance?

No. Spring washers (B0093-16-59, B0093-14-59) lose tension after initial use, increasing the risk of bolt loosening. Always replace spring washers when reinstalling fastening components to ensure structural stability.
