KNF Expands Line of Swing-Piston Pumps

FLUID POWER:  Two new KNF swing-piston pumps introduce ideal solutions to transfer, evacuate, or compress air or inert gas and deliver oil-free performance without any potential risk of contamination. The new models include a compact and efficient 3.3 l/m micro pump and a 25 l/m mid-size version with both providing vacuum or pressure capabilities.Their addition broadens the KNF swing-piston product line to include pumps offering flow ranges of 3.3 l/m, 9 l/m, 18 l/m, 25 l/m, 50 l/m and 78 l/m with vacuums to 27.6 inch Hg and pressures up to 100 psig., depending on type.

Among features, the sealing lip between the cylinder and wall has been designed to minimize frictional loss and promote a long service life, while running quietly with minimal vibration. Pumps can operate in any position and are supplied ready for installation.

All versions can be specified with ac motors, brush-commutated dc motors or brushless dc motors (with brushless types engineered for longer service life and allowing for pinpoint speed control).

These pumps can be used for a wide range of OEM applications requiring reliable pneumatics. Standard versions can be customized to meet particular OEM requirements.
