Designed to meet the specific demands of the biotech and pharmaceutical industry, MR UltraPure is the well-proven liquid ring pump for CIP return pump duties or for the efficient transfer of liquids containing gases.
 
 
The MR UltraPure is a reliable, low-maintenance self-priming liquid ring pump specifically designed for transferring liquids that contain air or other gases or for use as a CIP return pump for the complete removal of fluid from tanks. Surfaces, drainage capabilities and materials are optimized and documented to match the high demands of the biopharm industry.

The MR pump is also available in a standard version suitable for general food and beverage applications etc.
 
Crevice-free design and smooth surfaces prevent bacterial build-up and simplify cleaning.
The external shaft seal also secures maximum cleanability by placing difficult-to-clean parts on the outside of the pump. This saves time and reduces consumption of cleaning agents and high-purity water.
 
The materials used in the MR UltraPure have been carefully selected to secure high product integrity and to minimize the risks of reactive materials.
Materials made of steel are fully traceable in accordance with the EN10204 3.1 standard. Elastomers comply with the U.S. Food and Drug Administration (FDA) requirements and are tested and certified in accordance with USP Class VI section 87 and 88. In addition, all elastomers are traceable by compound identification number.
The external shaft seal ensures that wear particles from the shaft seal are directed by centrifugal force to the outside and thus do not come into contact with the medicinal product.
This attention to detail provides full control, minimizes risks during maintenance and facilitates change control procedures.
 
With few wear parts, the external shaft seal is designed for high performance and low maintenance.
The centrifugal forces press the liquid to the shaft seal area which provides good cooling and lubrication and prolongs the service life of the seal.
The stationary seal ring is solidly affixed to the back plate, providing perfectly aligned seal surfaces even after long periods of operation and potential pressure shocks or vibration in the system.
The true front-loaded design ensures that the seal can be quickly and easily replaced.
 
All equipment and components in the Alfa Laval BioPharm portfolio are supplied with Alfa Laval Q-doc, a comprehensive documentation package that provides full transparency of the entire supply chain, from raw material to final equipment delivery.
This smoothes purchasing and installation procedures as well as facilitates qualification, validation and change control procedures.
Based on GDP (Good Documentation Practice), Alfa Laval Q-doc covers every aspect of BioPharm equipment supply and provides customers with transparent and well-documented quality assurance of the sourced equipment.

The Q-doc package for MR UltraPure comprises equipment manuals, performance tests, quality and manufacturing procedures, material certificates, traceability of product wetted parts and the necessary parts and service information. This attention to detail maximizes uptime and minimizes risk.
 
MR UltraPure liquid ring pumps are available in four different sizes with capacities up to 80 m3/h and pressures up to 5.3 bar.
All standard components are kept in stock to shorten lead times and prevent unplanned downtime.
Standard pumps can be supplied within two weeks.
 
Alfa Laval provides a three-year warranty for all non-wearing parts, provided genuine parts are used.
 
Alfa Laval offers a comprehensive range of general food pumps and a specific UltraPure range suitable for the needs of the biopharm industry.
