Designed for the Field Technician in mind!

The Alexis® compact peristaltic pump can either run on its self-contained internal 30 amp AGM battery or plug it into a 120-volt electric socket. The Alexis® only weighs 37 pounds making this peristaltic pump lightweight and extremely durable. The rugged Pelican™ 1430 case enclosure is made of impact and corrosion resistant ABS plastic to withstand demanding work conditions. Incorporating the most accurate and precise variable speed controller for consistent flow rates ensures the technician reliable sample integrity. The Alexis® peristaltic pump includes a built-in digital display and sealed push buttons to control several unique functions of this diversified peristaltic pump. And always remember ….. Sample Like A Champ!

Constant Voltage Boosting Technology (CVBT)

Proprietary system that boosts a “low voltage battery” to an amazing range of 13.5 volts.  That means faster water discharge rates and more consistent pumping rates. Which in turn makes your next groundwater field sampling event a profit center!

Masterflex Easyload™ 2 pump head design

Super fast tubing load times; No more stretching and jamming silicon tubing through the pump head and defiantly no more fiddling with screws to gain access to the pump head. Located on the side of the rugged Pelican case exterior allowing the user to easily shut the enclosure.

Long Lasting Internal AGM Battery with Precise Push Button Technology

An amazing 30 Amp AGM rechargeable long-life internal battery! The benefits of a 30 Amp AGM battery means you get extra long sampling runs. How does up to 9 hours of continuous sampling running at a full 100%! Now you will get the job done faster by eliminating the need to carry an external battery for your small peristaltic pumps and always fearing that you may run the battery out during long sampling events (or even worse off forgetting the battery at the office). With the convenient internal battery charger indicator, you will know exactly how much battery power is left with a simple push of a button! Have a power supply? With the AC or 12v DC adapters, you can setup and run your Alexis® peristaltic pump indefinitely.

Super strong – Light weight Pelican™ 1430 case

The Alexis® small peristaltic pump utilizes a Pelican™ 1430 case that lends hand to hand durability and weighs only 37 pounds. The rugged Pelican™ case enclosure is made of impact and corrosion resistant ABS plastic to withstand demanding work conditions.

Tell Me More LCD Display

That means you will visually see

your current setting on the LCD

screen when retrieving a sample.

Push Button Back Flushing

Supplied with a push button reversible flow feature for back-flushing.

Low Voltage Disconnect Warning (LVD)

Simply put, the LVD is a “battery saver device”. If the internal battery should ever fall below 10.75 volts into the critical “red” level of the “Internal Battery Charger Indicator” area then the Alexis® will turn off…. In short, the LVD telling you that the internal battery needs a charge. This advanced technology will prolong the life of the internal battery.

Protection From Reverse Polarity

If you should reverse polarity the battery clamps when hooking up the Alexis® peristaltic pump to an external battery, the built in internal protection engages not allowing the Alexis® pump to turn on.
