KNAUERDOSING PUMPS

KNAUER dosing pumps are highly accurate two-piston pumps for applications in the chemical and pharmaceutical industries as well as in research and method development. They pump and dose aqueous and organic liquids, aggressive media, or liquid gases. The metering pumps impress with their high chemical resistance, excellent flow rate precision and low pulsation of the pumped medium in a wide range of applications.

• Flow rates from 0.01 ml/min to 1000 ml/min
• High pressure ranges up to 650 bar
• Wide temperature ranges from -10 °C to 120 °C
• Viscous liquids up to 1000 mPa s
• Special features on request

KNAUER dosing pumps are integrated easily in your dosing application due to an independent control via display or touchscreen.

BlueShadow Pump 40P

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.

BlueShadow Pump 80P

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.

AZURA® Pump P 2.1S

AZURA® Pump P 2.1S was developed for high-pressure dosing applications of up to 400 bar and for flow rates of up to 50 ml/min. Whenever a compact and the easy-tointegrate pump is required, this pump is a perfect choice. The exchangeable pump heads are compatible with a wide range of chemicals and the versatile control options allow easy remote and standalone operation. For aggressive liquids, a Hastelloy® C version is available.

AZURA® Pump P 4.1S

AZURA® Pump P 4.1S was developed for high-pressure dosing applications of up to 400 bar and for flow rates of up to 50 ml/min. Whenever a compact and the easy-to-integrate pump is required, this pump is a perfect choice. The pump contains a manual purge valve with a built-in pressure sensor. The pump automatically stops the flow when minimum or maximum pressure limits are reached. The exchangeable pump heads are compatible with a wide range of chemicals and the versatile control options allow easy remote and standalone operation.
