The SP-LP-200 is a heavy-duty, high-performance fine mist sprayer engineered specifically for highly permeable lipophilic formulations, pure essential oils, and aggressive chemical solvents. Unlike conventional single-gasket sprayers that suffer from rapid polymer swelling, mechanical seizure, and creeping capillary leaks, our pump features an advanced, decoupled “Dual-Barrier Sealing System”.

By utilizing an inner high-density Fluoropolymer (FKM / Viton) inner plug and an outer high-rigidity double-lip seal ring, the SP-LP-200 completely eliminates upward fluid migration and locks out atmospheric oxygen. This guarantees an uncompromised, clean overcap interior and a perfectly atomized micro-droplet spray profile throughout the product’s entire shelf life.

2. Key Features & Industrial Advantages

• Dual-Action Oil Proofing (Zero Seepage): The FKM inner core of the SP-LP-200 features superior resistance to terpenes and lipophilic compounds, maintaining a near-zero swelling ratio. The outer double-lip ring continuously cleans the piston rod during actuation, ensuring no sweating, zero leakage, and a bone-dry overcap interior.
• Ultra-Consistent Fine Mist Atomization: Outfitted with precision-machined orifice shear-inserts, the SP-LP-200 delivers a perfectly distributed, misty spray plume even for viscous oil formulations, completely eliminating streaming, spitting, or large droplet formations.
• Fatigue-Free Extended Mechanical Life: Internal mechanics are shielded from direct contact with corrosive active ingredients. The SP-LP-200 is validated to endure more than 100,000 actuations without loss of structural spring rebound or sealing elasticity.
• Isolated Fluid Pathway Option: The SP-LP-200 can be configured with an external spring structure, ensuring that the liquid pathway never contacts metal components. This completely eliminates the risk of trace iron-ion contamination or oil discoloration in sensitive cosmetics or pharmaceuticals.
