Let’s Dive into Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC
The Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC is a hand-operated vacuum pump designed for a variety of applications. Manufactured by Nalge Nunc, it boasts a 36cc displacement and a built-in gauge for precise vacuum control, making it a potentially valuable tool for laboratory work, field research, and even some unexpected uses like… goat milking?
My journey to this particular pump started with a need for a more efficient milking solution for my small goat herd. My existing 15cc pump was functional but time-consuming, and the promise of a higher displacement intrigued me. I was hoping the Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC would significantly reduce milking time while providing consistent vacuum pressure.
Upon unboxing, the pump felt solid and well-constructed, although the PVC material gave it a slightly less robust feel than metal alternatives. The gauge was clear and easy to read, and the handle provided a decent grip. Initially, I was excited about the potential of this pump to improve my goat-milking efficiency.
Compared to my existing 15cc hand pump, the Nalge Nunc felt noticeably larger and more substantial. I considered a small electric pump, but I wanted something portable and reliable in off-grid scenarios. My decision ultimately came down to the Nalge Nunc’s larger displacement volume, hoping it would make the milking process quicker. My first impression was mixed; the build quality seemed adequate, but the larger size hinted at a potentially harder pumping action.
Real-World Testing: Putting Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC to the Test
First Use Experience
My initial test involved using the Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC for milking one of my does, Bess. I set up the pump, connected it to my existing milking system, and began pumping.
The first thing I noticed was the significant effort required to create a vacuum. The larger displacement, while theoretically faster, made each stroke considerably harder than with my smaller pump. After a few minutes of struggling, I found that maintaining a consistent vacuum proved surprisingly strenuous.
Extended Use & Reliability
After several weeks of intermittent use, my initial concerns regarding the pumping effort only intensified. The PVC construction seemed durable enough for my limited use, but I doubt it would withstand heavy, daily use in a professional lab setting. Cleaning the pump was relatively straightforward, although I worry about the longevity of the internal seals.
Compared to my experience with my older, smaller pump, the Nalge Nunc was a disappointment. The increased pumping effort negated any potential time savings from the larger displacement. In hindsight, the Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC felt like a step backward in terms of practicality for milking purposes.
Breaking Down the Features of Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC
Specifications
The Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC boasts a 36cc displacement volume. This means it moves 36 cubic centimeters of air per pump stroke, designed for rapid vacuum creation.
It’s constructed from durable PVC, which is chemically resistant but less robust than metal alternatives. This construction helps keep the weight down but might limit its lifespan under heavy use.
The pump includes a built-in gauge that displays the vacuum pressure in inches of mercury (in. Hg). This provides precise control and monitoring of the vacuum level.
It is a hand-operated pump, requiring manual pumping to create a vacuum. This design makes it portable and independent of electricity.
The pump is designed to achieve and hold a vacuum of 25 in. (635 mm) Hg. This level is sufficient for many laboratory and field applications.
Performance & Functionality
The primary function of the Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC is to create and maintain a vacuum. It does achieve this, but the effort required is a significant drawback, at least in my application. The gauge is accurate and provides valuable feedback, but the strenuous pumping action undermines the overall usability.
The pump’s strength lies in its portability and independence from power. Its weakness is the high physical demand required to operate it effectively. For my purposes, it fell short of expectations due to the difficulty of maintaining a consistent vacuum pressure while milking.
Design & Ergonomics
The PVC construction keeps the pump relatively lightweight, but the handle design could be improved for better ergonomics. The pump feels bulky, and the pumping action isn’t particularly smooth. A more contoured handle and a smoother pumping mechanism would enhance user comfort.
There’s a slight learning curve in mastering the pumping technique to achieve the desired vacuum level efficiently. The gauge is straightforward, but continuous monitoring and adjustment are necessary due to the pump’s hand-operated nature.
Durability & Maintenance
While the PVC seems reasonably durable, the internal seals are a potential point of failure over time. Regular cleaning is essential to prevent contamination and maintain optimal performance. Repairing the pump seems feasible due to its relatively simple design, but replacement parts availability might be a concern.
Accessories and Customization Options
The Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC doesn’t come with many accessories beyond the standard fittings. Customization options are limited, although users might be able to adapt different tubing or connectors for specific applications. Compatibility with third-party accessories depends on the connector sizes and vacuum requirements.

Who Should Buy Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC?
The Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC could be suitable for laboratory technicians or field researchers who need a portable vacuum source for occasional use. It is also ideal for those who prioritize manual operation and precise gauge control.
This product is not ideal for individuals needing continuous vacuum pressure or those with limited physical strength. Consider an electric vacuum pump for applications requiring consistent, hands-free operation. Essential accessories include appropriate tubing and connectors for the specific application.
Conclusion on Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC
The Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC offers portability and precise vacuum control, but its demanding pumping action limits its practicality for certain applications. At $639.99, the price seems high considering the PVC construction and the physical effort required.
I would not personally recommend this pump for milking goats, as the strenuous pumping outweighs any potential benefits. However, for specific laboratory or field applications requiring manual vacuum control, it could be a viable option.
