Micro-diaphragm pump

The Type NF1.60 micro-diaphragm pump for dosing or transferring liquids or liquid-gas mixtures, delivers flow rates up to 650 ml/min, self-primes to 8.86-in.-Hg suction, and operates against pressures up to 87 psi both intermittently and continuously.

The pumps use a patented valve system featuring precise valve structures and benefit from sophisticated diaphragm technology to achieve high levels of efficiency. They can be powered either by a brush-commutated dc motor or brushless-dc motor to promote extended service life. The pumps run dry, perform virtually maintenance-free, and can be mounted easily in any position.

Components that will come into contact with the pumped medium are made from PP, PTFE, EPDM, and FFMP for chemical resistance. Most neutral and aggressive liquids can be handled without risk of corrosion or other damage. A wide range of standard voltages and frequencies can be specified.
