19-KIT-110 Hach KNF300 Pump 6-Month Service Kit

The KNF300 Pump 6-Month Service Kit (Product Number: 19-KIT-110) is a curated set of original manufacturer wear parts specifically for the KNF300 diaphragm pumps integrated into BioTector B7000i systems. These pumps are the "heart" of the fluidic system, responsible for moving samples and aggressive reagents through the analyzer. The kit typically includes critical components such as replacement diaphragms, valve plates, and specialized O-rings. Because these parts are in constant motion and frequently exposed to chemical vapors, they are subject to fatigue and loss of elasticity. Replacing them every six months is a vital step in preventing pump failure, maintaining airtight seals, and ensuring the analyzer’s Two-Stage Advanced Oxidation (TSAO) process operates under the correct pneumatic conditions.

Advantages

• Optimized Pump Performance: Regular replacement of diaphragms and valves ensures the pump maintains its original flow rate and vacuum/pressure specifications.
• Chemical Resistance: Components are made from high-grade elastomers designed to withstand the aggressive reagents used in BioTector oxidation cycles.
• Uninterrupted Operation: Proactive 6-month maintenance prevents unexpected pump diaphragm ruptures, which could lead to significant analyzer downtime.
• Original Equipment Quality: Contains genuine Hach/KNF parts, ensuring a perfect mechanical fit and maintaining the analyzer's factory warranty.
• Cost-Effective Maintenance: Bundling all necessary pump wear parts into a single kit simplifies the service process compared to sourcing individual gaskets or valves.
• Precision Sampling: By ensuring the pump remains airtight, the kit helps maintain the accuracy of sample aliquot volumes delivered to the reaction chamber.
