Two-stage pump with self-drying for automatic condensate drain in labs.
The KNF Laboport SD N 820.3 FT.40.18 is a sophisticated two-stage diaphragm pump equipped with an automated self-drying mechanism for efficient removal of condensate. Designed for laboratory environments, it's ideal when handling humid vapors and when a clean, ecological vacuum is imperative. This device excels in applications such as vacuum ovens for chemical or biological sample drying and autoclaves for sterilization of various materials. Its innovative use of anti-corrosion materials allows for the handling of corrosive substances without compromising performance.
At the core of the pump lies a PTFE-coated diaphragm, optimized for exceptional performance and longevity, even in rigorous applications. The self-drying system operates by intermittently opening a solenoid valve to admit ambient air, effectively removing any condensation that forms within the pump head and restoring full performance capability.

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
