Chemically resistant liquid transfer diaphragm pump. Offers wetted material combinations for optimal chemical resistance. Manual control of flow rate with LED indicator. For convenient transfer and dosing of neutral or corrosive liquids. Option for analog and impulse control (RC).

• Premium corrosion resistance
• Manual front-panel flowrate control
• Pressure limit protection
• No metal wetted parts to corrode
• Reliable splash-proof housing
• Models are offered with either PP, PVDF or PTFE pump head material depending on the liquid being transferred
• All models feature PTFE diaphragms and FFPM valves
• NF300 has a maximum pressure of 1 bar and NF1.300 has a maximum pressure of 4 bar

Pumps are self-priming, maintenance-free and will operate dry indefinitely without damage. Select the best pump based on the desired flowrate, maximum outlet pressure and the wetted materials.

Three considerations for any liquid diaphragm application: The inlet of pump should not be lower than the level of liquid being transferred. An inlet filter is required if media contains particulates or fibers larger than 50 µm. Pulsation varies between specific pump models.

Flow rate: 0.5 to 3 L/min
