KNF Neuberger PM16209-122 Diaphram Pump

• Laboratory vacuum and pressure applications, including filtration, distillation, and gas sampling.
• Transfer of corrosive or sensitive fluids in chemical and pharmaceutical research.
• Original equipment manufacturer (OEM) integration for analytical instruments and medical devices.
• Environmental monitoring for air and gas analysis.
• Inkjet printing systems requiring precise fluid delivery.

Typical flow rate

For this class of KNF diaphragm pump, flow rates commonly range from a few litres per minute up to approximately 20 litres per minute, depending on the specific configuration.

Typical ultimate vacuum

Units of this type typically achieve an ultimate vacuum in the range of 100 to 200 mbar absolute.

Typical operating pressure

Pressure capabilities commonly extend up to 2.5 bar (gauge) for this model series.

Power supply

KNF diaphragm pumps are commonly available in 12V DC, 24V DC, or various AC voltages (e.g., 230V AC, 50Hz) depending on the motor fitted.

Wetted materials

Common wetted materials for KNF diaphragm pumps include PTFE, PVDF, and FFKM, offering broad chemical resistance.

Footprint

These are compact units; typical dimensions for a pump of this series are around 150mm x 100mm x 100mm, though this can vary.

• What is the primary advantage of a diaphragm pump for laboratory use?

  Diaphragm pumps offer oil-free operation, preventing contamination of pumped media and eliminating the need for oil changes. Their robust design also provides excellent chemical resistance.

• Can this pump handle aggressive chemicals?

• Is this unit suitable for continuous operation?

• What maintenance is typically required for a diaphragm pump?

• What does 'compact and corrosion-resistant' imply for integration?

Diaphragm pumps are generally valued for their reliability and versatility across laboratory and pharmaceutical applications. Buyers typically prioritise condition of the diaphragm itself, seals and valve integrity when purchasing used units. Industry sentiment favours their gentle handling of sensitive fluids, low maintenance requirements and ability to manage viscous or abrasive media. Common strengths include self-priming capability, compact design and suitability for both suction and discharge applications. Durability remains a key selling point.
