• Bolted Construction: Offers superior flow rates, up to 35% higher than competing models, and longer diaphragm life due to an improved flow path design.
• Simple Replacement: The bolted-down footprint and inlet/discharge connections are identical to Wilden's clamped counterparts, making it easy to replace.
• Greater Containment: Built to offer enhanced containment capabilities for various industrial uses.
• Threaded Inlet/Discharge Connections: Available in NPT or BSPT (P820 model).
• No-Weld or Nipple Attachment: Options for DIN or ANSI flanged inlet/discharge connections (P830 model).
• Extensive Chemical Compatibility: The pump is designed to handle a wide range of chemicals, making it versatile for various industries.
• Submersible and Portable: It is suitable for both submersible and portable use, offering flexibility in different environments.
• Large Passage and High-Lift Suction: Ensures efficient flow and the ability to handle high-lift suction applications.
• Ease of Use and Maintenance: The design ensures simple operation and ease of upkeep, reducing downtime.
• Adjustable Internal Manifolds: Features manifolds with adjustable internal settings for increased customization and efficiency.
• Increased Dependability: The pump has been designed for long-term reliability, ensuring longer mean time between repairs (MTBR) and less frequent maintenance.
