Peristaltic Pump: A Complete Guide to This Essential Fluid Handling Solution
EE+S carries three peristaltic pump lines for low-flow groundwater sampling and fluid dosing: the Proactive Alexis and Proactive Athena, and the Solinst Model 410. The Alexis is available both to buy and to rent for project-based work; the Athena and Solinst 410 are sold outright. Peristaltic pumps are the standard choice when the fluid can’t contact any pump internals — low-flow purging, metals sampling, and chemical dosing.
Which Peristaltic Pump Do You Need?
| Pump | Buy | Rent | Best For |
|---|---|---|---|
| Proactive Alexis | Yes ($1,626) | Yes (daily/weekly/monthly) | Field sampling where flexibility between owning and renting matters |
| Proactive Athena | Yes ($1,160) | Not currently listed as a rental | Lower-cost dedicated sampling or dosing pump |
| Solinst Model 410 | Yes ($1,110) | Not currently listed as a rental | Dedicated groundwater sampling pump |
| Masterflex E/S | Not currently sold | Yes (daily/weekly/monthly) | Short-term or project-based rental only |
Peristaltic Pump Options, Explained
Proactive Alexis
EE+S’s Proactive Alexis Peristaltic Pump is available both to purchase and to rent, which makes it the flexible choice if you’re not sure yet whether a project needs an owned pump or a short-term rental.
Proactive Athena
The Proactive Athena Peristaltic Pump is EE+S’s lower-cost peristaltic option, sold outright rather than offered as a rental.
Solinst Model 410
The Solinst Model 410 Peristaltic Pump is a dedicated sampling pump from Solinst, a name well known in groundwater monitoring equipment.
Masterflex E/S (Rental Only)
If a project only needs a peristaltic pump for a short window, the Masterflex E/S Peristaltic Pump is available through EE+S’s rental fleet without the commitment of a purchase.
How Peristaltic Pumps Work
A peristaltic pump is a positive displacement pump that moves fluid by compressing a flexible tube with rotating rollers, rather than using an impeller or valves. Because the fluid only ever touches the tubing, not the pump’s internal mechanism, contamination risk is low — which is exactly why they’re the standard choice for groundwater sampling, metals analysis, and chemical dosing.
Where Peristaltic Pumps Fit in Environmental Work
- Low-flow groundwater sampling: pumping from shallow or narrow monitoring wells without disturbing the sample.
- Metals and general water quality sampling: the closed-tube design avoids introducing contamination into the sample.
- Chemical dosing: precise, consistent flow for dosing chlorine, pH adjusters, and similar chemicals in water treatment.
How to Choose the Right Pump
- Flow rate: confirm the pump covers the range your sampling protocol or dosing application requires.
- Tubing material: match tubing chemistry to your fluid to prevent degradation or contamination.
- Buy or rent: a one-off or short-duration project usually favors renting; recurring field work usually favors owning.
- Talk to EE+S: we’ll confirm the right pump and tubing combination for your specific sampling or dosing application.
FAQ
What’s the difference between the Proactive Alexis and Athena peristaltic pumps?
Both are Proactive peristaltic pumps sold by EE+S; the main practical difference is that the Alexis is also available to rent, while the Athena is sold outright and priced lower. Talk to a specialist to confirm which fits your flow rate and application.
Can I rent a peristaltic pump instead of buying one?
Yes — EE+S rents the Proactive Alexis and the Masterflex E/S peristaltic pumps for project-based work. The Athena and Solinst 410 are currently sold only.
What flow rate do I need for groundwater sampling?
It depends on your sampling protocol and well conditions — low-flow purging typically calls for a slower, more controlled rate than general dosing applications. EE+S can help match a pump and tubing setup to your specific project.
