Demanding metering applications for liquids with different viscosities or precise batch dosing tasks need a particularly exact control of the flow rate. Since KNAUER pumps support a wide variety of communication interfaces, their pumps can be combined with a range of mass flow controllers to meet these challenging demands. KNAUER pumps can also be easily integrated into pilot plants or process environments.

Strong acids and bases are often required for different liquid applications. KNAUER offers pumps with a choice of different pump head materials which can be used for demanding dosing tasks. Furthermore the pump design allows an easy replacement of parts which come in contact with aggressive and corrosive chemicals.

This makes the KNAUER pumps ideal for metering aggressive liquids.

Highly viscous liquids dosing pumps

One important property of liquids is their viscosity and many pumps will struggle with highly viscous media. When bottling honey, it is typically heated moderately to reduce its viscosity, a principle applicable also to many other highly viscous liquids. If an increase of the liquid temperature is not suitable, pumps with a high engine performance will be required. KNAUER pumps with their powerful motor drives are adequate for these demanding conditions.

The Smartline Pneumatic Pump 1950, powered by compressed air, has been designed for constant pressure applications. It is suitable for packing high performance columns (microbore, analytical and preparative ) up to 1 000 bar. The flow is highly reproducible, and only little maintenance efforts are required. It features a double-piston design and can be configured with four different pump heads to meet a broad range of requirements in flow and pressure ranges.

Sometimes the supply of media or starting materials for a chemical reaction needs to be heated to properly meet the conditions of the process. This is where standard high pressure pumps can reach their limits. KNAUER dosing pumps withstand moderate liquid temperatures and can be equipped with thermally decoupled pump heads even for elevated temperatures.

It is also possible to equip the pump with a pump head heating device for temperature sensitive applications.

KNAUER pumps cover a wide range of different demands. Chemical compatibility and working temperatures are just two possible requirements. Pumping liquids at low temperatures may be required in flow chemistry or in various applications involving liquefied gases. The wetted parts of the KNAUER pumps are capable of working under these conditions. With an optional pump head cooling device these pumps are perfect for dosing or feeding of liquefied gases or cooled liquids

Sensitive bioprocess applications requires pump equipment that will not interfere with the chemical and biological processes being carried out. KNAUER offers pump heads in a biocompatible titanium or ceramic version, enabling a wide range of sensitive applications in the pharmacy and biotechnology.

The BlueShadow Pump 40P was designed to provide exceptionally precise and reliable solvent delivery for a wide range of dosing applications. Exchangeable pump heads with maximum flow rates of 10 and 50 ml/min cover a wide range of high-pressure dosing tasks. Practically pulse-free flow is achieved by our enhanced smart drive control which actively prevents pressure ripple instead of just dampening it. The improved design features a built-in inline filter and low dead volume fluidic path. Change your metering rate with the wipeable membrane keyboard or use the remote control from your process control system. Pump heads for high-temperature applications enable solvent delivery at up to 120°C. Minimize temperature gradients by adding a pump head heater and insulation sleeve.

The BlueShadow Pump 80P delivers stable and precise solvent flow for your dosing application. Available in stainless steel or biocompatible titanium versions, the pump heads enable a wide range of applications. The integrated automatic recognition of the pump head with RFID technology allows the fast adaption of the pump. Change from  low-flow organic solvent delivery to high-flow biocompatible buffer metering with minimum downtime. By adding one or more additional pumps, binary, ternary or even quaternary highpressure mixing gradient systems can be easily configured. The pump can also be equipped with a binary or ternary gradient valve block to configure cost-effective low-pressure gradient mixing systems. Exchangeable pump heads for flow rates up to 1 000 ml/min and pressures up to 40 MPa make it possible to easily adapt the pump to changing performance requirements and allow simple maintenance.
