Description, Operating Conditions

KNF pumps in the range N 86 KN.18 and N 811KN.18 transfer, evacuate and compress 100 % oil-free. In operation they are gas-tight, and maintenance-free.

Electrical Equipment

• See table 1 for fall electrical data
• The protection class of standard versions is IP 20
• The pumps are fitted with a thermal -switch to protect against over-loading.

Operating Conditions

• Handling air, gases, and vapors at temperatures between + 5°C...+ 40°C
• For maximum permissible operating pressure, ultimate vacuum, and flow capacity: see table 2. The pumps must not be used in areas where there is a danger of explosion
• KNFN86KN18andN811K:18 pumps must not be used for liquids. You will find suitable liquid pumps in our Product Program
• Before pumping a medium, the compatibility of materials of pump head, diaphragm and valves with the medium must be checked (for pump materials: see table 3).

If your potential application lies outside the above limits discuss it with our technical adviser

Ambient Condition

When the pumps are operating the following ambient conditions must be maintained:

• Ambient temperature during Operation: between + 5° C .... + 40°C
• During Operation an adequate supply of air for cooling must be provided
• The pumps must not be used in areas where there is a danger of explosion.
