KNF's new NF liquid pumps are the convenient way to transfer liquids in the laboratory without the mess of peristaltic tubing. They are stylish and compact, and PTFE models are highly resistant to chemical attack, prevent contamination of your pumped medium. They provide the longest possible lifetime when pumping corrosive liquids such as acids, gases and vapors. Available with either local or external control capabilities, including 0-10 VDC, Start/Stop via TTL contact, and Output Fault Alarm.

The NF100 and NF300 pumps are available in either polypropylene, PVDF or PTFE head materials, with FFPM valves. You should always check corrosion compatibility charts with the medium you intend to pump.

Adjustable Diaphragm Valves

This diaphragm valve is small, can be continuously adjusted and is suitable for air and liquid. It can be used in many ways, e.g. as an overpressure safety valve, inducing a backpressure or preventing liquid from being sucked / pushed through the pump.

Pulsation Damper

This pulsation damper eliminates up to 97% of the outgoing pulsation and can be used for different purposes: - reduction of vibration in the hoses / pipes - protection of expensive measuring instruments after the pump - improving pulsation sensitive processes.

These compact, reliable, high-performance metering pumps replace maintenance-intensive peristaltic pumps and are designed for use with neutral and aggressive liquids. They feature continuous and steady flow, even at low rpm, using a quiet, brushless, 3-phase stepper motor that ensures that the suction cycle is completed at maximum speed, but the output cycle is variably controlled per the programmed speed. Constant speed changes by the motor and electronic control provide steady output over the entire cycle. The pump provides manually-adjustable speeds and menu-driven calibration. The cabinet is stylish, lightweight and splashproof. They are available in two versions; front panel control only, and remote PC control capable.
