Pump tubing and fluid characteristics The flow rate and fluid dynamics through a peristaltic pump are affected by the dimensions of the tubing, the design of the pump manifold, the geometry of the tube occlusion bed, the number of rollers, and by the overall diameter of the roller assembly. Masterflex Single-Use Systems and Assemblies. They feature stainless steel rotors, Rulon rollers, and PSF ends.
Fluid applications Fixed-speed and fixed-occlusion pumps are popular for their flow rate repeatability, consistent tube loading, and general ease of use.

Precise dispensing and metering, analytical techniques in research and quality assurance, and environmental sampling and monitoring require this high level of performance and accuracy. Cartridge pumps have long rollers that provide synchronous fluid delivery between the cartridges. Compatible with L/S drives that accept two or more pump heads and have a 1/10 hp minimum.
Multichannel heads deliver between-channel flow accuracies in the range of 1.5 to 2%. Fine adjustments to the occlusion in individual channels can effectively compensate for any minor variations in tubing dimensions that lead to slight variations in flow. All Rights Reserved. Masterflex L/S multichannel pump heads are available for microbore tubing and for Masterflex L/S tubing sizes. 
2022 Masterflex, LLC. Low-viscosity, water-like fluids move easily through many different sizes of tubing. Speed Control: 2% (1-turn speed control) Cartridge pump heads are available separately, or integral to the design of the pump. Tubing with a higher ratio of wall thickness to inside diameter (thick-wall tubing) will generate greater suction lift (relative to thin wall tubing of the same ID) and is recommended for more viscous fluids. Dedicated to the success of your entire fluid path from research to production since 1955. 
To ensure accuracy, it is important to use high-tolerance precision pump tubing and to calibrate the pump.

Revers Cole Parmer Masterflex 77521-50 Console Drive 1-100 RPM USED (7114) R New design and automatic tubing retention allow for multiple tubing sizeschange tubing without removing head from drive Stackable heads are preferred for larger tubing sizes, and when the application involves high suction lift and/or discharge pressure. Depending on features and performance level, digital drives also offer display of flow rate, pump speed (rpm), dispense volume, and cumulative volume (total volume dispensed over multiple dispense cycles. Some stackable pump heads must be dismantled or removed from the drive in order to replace the tubing. This is a valuable benefit for proportional flow applications as it allows you to mix and match tubing sizes or pump head styles to get the proportional flow rates required. Choose pump heads for microbore tubing, L/S Precision tubing, or L/S High-Performance Precision tubing based on your application requirements. Recommended for use with large cartridge 07519-75 and L/S Precision tubing sizes L/S 14. 4 variations of this product are available. Stackable pump heads that incorporate an offset roller design limit the torque loading on the drive circuit when two or more pump heads are mounted together.
