How to select your Masterflex pump system

Define your application requirements:

What flow rate do I need?
What chemical am I pumping?
Do conditions like fluid viscosity or back pressure play an essential role in my application?

Select a pump series based on your flow rate:

Masterflex Ismatec 0.002 to 37 mL/min
Masterflex L/S 0.0006 to 3400 mL/min
Masterflex I/P 0.012 to 13 LPM
Masterflex B/T 0.3 to 45 LPM

Select the components to fit your application:

I/P and L/S pumps systems are divided into three categories: pump head, tubing, and drive.
Masterflex Ismatec and B/T pumps systems are divided into two categories: pump head and drive.
To complete your tubing pump system, choose a pump head, tubing, and drive from within the same series.

What to consider

Choosing a pump head

Flow rate: Different pump heads have different flow rate capabilities
Frequency of tubing changes: Some pump heads enable very rapid tubing changes
Desired number of channels: Pump heads are stackable in most cases
Chemical compatibility: The materials used for the pump head is important in order to combat any chemical spills
Accuracy: Standard pump heads deliver the most accurate and repeatable flow rates

Choosing tubing

Size: Inner and outer diameter of the tubing determine flow range, maximum pressure, and ability to handle viscous fluids well.
Temperature: Higher fluid or environmental temperatures will decrease tubing life. Sometimes a layered tube will alleviate these concerns.
Application: Special considerations for your application of industry such as adherence to federal or other regulations such as FDA 21 cfr 177.2600 and USP Class VI, soft or hard particulates, or high viscosities are some examples.
Media: Choose the formulation that will be least affected by your fluid's chemical nature
Pressure: Higher pressures can result in decreased pump tubing life and increased possibility of rupture. This can be mitigated with thicker tube walls in conjunction with a pump head architecture that supports those pressure ranges. Additionally, tube or barb locks to fit over tubing connectors will help reduce the risk of rupture at those points

Choosing a drive

Flow rate: The rpm of the drive directly correlates to flow rate
Fixed- or variable-speed: Variable-speed drives enable flow rate adjustment
Accuracy of flow rate or dispense volume: Many drives have digital speed control circuitry for highly accurate and repeatable flow rates
Remote control via analog signal or cloud: Some drives can connect to your process controller or can be operated by a footswitch while others can be safely monitored or controlled by phone or webpage using the cloud
Environmental protection against hazards: Many drives are sealed against dust and water exposure

Pumps and components

Complete Pump Systems

Complete pump systems include all the pump components you need to get pumping in no time at all. Our pump system includes a pump drive, pump head and pump tubing.

Peristaltic Pumps

Masterflex peristaltic pump systems provide flexibility based on your needs and requirements. Masterflex pumps can be configured as your needs change — just switch out the pump head and the tubing to match your new requirements.

Pump Heads

Standard pump heads offer the most accurate, repeatable flow rates.

Peristaltic Pump Tubing

Precision extruded and pump tested formulations engineered to provide the highest quality for tubing life, pressure, and suction lift.

Masterflex vacuum pumps

Vacuum pumps, pressure pumps, cover a wide range of operating pressures. Laboratory/filtration vacuum pumps are for use in the lab or anywhere a low vacuum is needed; typically offer both vacuum and pressure capabilities. Use rough vacuum pumps (or roughing pumps) for laboratory and industrial applications requiring a level of vacuum less than 10–3 Torr. Use high vacuum pressure pumps when you need vacuums higher than 10–3 Torr. Also, consider the free-air capacity needed (the higher the free air capacity, the faster it will evacuate the chamber) and whether you need a lubricated (oiled) or non-lubricated (dry or oilless) pump. Lubricated pumps provide higher capacities, higher vacuum levels, and lower noise, but can contaminate the system and require more maintenance. Select a nonlubricated pump for vacuum in a clean system and low maintenance.
