The chemically-resistant series N860.3FTP diaphragm pump is KNF's largest laboratory twin-head unit. There is a wide range of applications for this pump in the lab. It is used especially whenever clean vacuum is required. Examples include vacuum-drying of vacuum oven chambers for drying or heat-treating substances and components or larger rotary evaporators, vessels, filters and textiles. Due to its high resistance to aggressive media, this pump can be used with most all solvents. The heart of these very compact pumps are KNF structured diaphragms (PTFE-coated). These patented diaphragms were stress-optimized using the Finite Elements method. As a result, we were able to make the pumps smaller while increasing the service life of the diaphragm.

INCLUDED: The KNF N 860.3 FT.18 IP54-T Diaphragm Pump includes:

  • Power Cord
  • Operator's Manual
  • Manufacturer's Documentation
  • 2 Year Manufacturer's Warranty

Why Questpair exists

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.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
