Product Details

• Cast iron impeller and volute are wear resistant for long life and minimal service
• Pump out vanes on back of impeller reduce debris accumulation and downtime while allowing greater productivity
• Carbon ceramic mechanical seal teamed with reliable four-cycle engine with low oil shutdown provides for increased operating life
• High strength lightweight die cast aluminum housing increases the years of trouble-free pump life
• A heavy-duty protective frame provides convenient carry handles while adding extra protection for the pump
• Self-priming high performance pump capable of handling solids up to 1/4 in, ideal for job sites with relatively clean waters

Wacker Neuson PG2A Dewatering Pump 

The Wacker Neuson PG2A Dewatering Pump is a self-priming centrifugal pump built to remove relatively clean water quickly and efficiently. If you need to clear standing water from job sites, foundations, utility vaults, or pools, this pump combines solid performance with portability. In this guide, we'll cover everything: technical specifications, performance, what makes it special, its pros and cons, how it compares to other models, and how to maintain it for best longevity.

What is the PG2A Pump?

The PG2A is part of Wacker Neuson’s PG Series of dewatering pumps. It is designed to be semi-clean water (light debris) capable, meaning it is great for removing water that’s reasonably free of heavy solids or sludge. It is not a "trash pump," which means you shouldn’t expect it to handle large chunks of debris or heavy mud, but it's excellent for many standard contractor or site-dewatering tasks.

The “PG2A” model is more compact and has lower flow than its larger sibling the PG3A, but offers enough power to move water efficiently for many applications.

Technical Specifications of PG2A

Here are the details for the PG2A, based on Wacker Neuson’s published data and supplier listings:

Key Features That Make PG2A Stand Out

• Self-priming centrifugal design: Once set up, it can prime itself to draw in water, useful when the pump inlet is above the water surface. 

• Lightweight aluminum housing & durable frame: Aluminum body parts keep weight down, while the frame protects engine and pump from bumps on the job. 

• Pump out vanes & wear-resistant impeller/volute: Helps reduce debris buildup and wear. Improved longevity and lower maintenance. 

• Reliable Honda engine: Known for reliability, easy starting, and good support. 

• Portability: The weight (~53 lb), size, and built-in handles make moving it feasible for one or two people. 

Performance and Use Cases

Here’s where the PG2A shines:

• Removing water from shallow foundations, trenches, and footings in construction.

• Dewatering flooded basements or utility vaults (assuming water is relatively clean).

• Draining swimming pools or ponds (without heavy solids).

• Site prep where water must be removed quickly but conditions aren’t brutal.

What it isn’t ideal for:

• Heavily silted, muddy, or trash-filled water (use a PT or trash pump for that).

• Very high vertical lifts beyond its head specs.

• Continuous heavy duty pumping over very long durations unless properly maintained.

Comparisons: PG2A vs PG3A vs PT2A

Note: “Trash Pump” models (PT series) are built for heavier, trash or solid-laden water; PG series is more for clean or lightly contaminated water.

Benefits of Using PG2A

• Efficiency: Moves large volumes of water for its size.

• Cost-effectiveness: Lower fuel consumption per gallon moved compared to over-sized pumps.

• Versatility: Good for many contractor, municipal, or residential dewatering needs.

• Durability: With the wear-resistant components, less frequent repair or parts replacement.

• Lower weight burden: Easier to transport and deploy.

Maintenance Tips for Longevity

To keep your PG2A running strong:

1. Check engine oil regularly — change as per manufacturer schedule.

2. Inspect and clean the strainer and intake area to reduce clogging.

3. Flush the pump housing after use if water contains sediment.

4. Check fuel quality — stale or contaminated fuel can harm performance.

5. Inspect seals and impeller for wear; replace as needed.

6. Store dry and protected from extreme weather and corrosion.

Frequently Asked Questions (FAQs)

Q1. Can the PG2A handle dirty water with mud or debris?
Answer: Yes, but only light debris up to ~0.25 inches. Heavy silt, stones, or sludge can damage the impeller or reduce performance.

Q2. Is the PG2A self-priming?
Answer: Yes. It’s designed to prime itself when set up properly at or slightly above water level.

Q3. What is the maximum vertical lift (head) I can expect?
Answer: Around 98 feet maximum discharge head. Suction lift (vertical distance water must be drawn) up to 25 feet. If you exceed these, performance drops.

Q4. How long will the pump run on a full tank?
Answer: Approximately 1.9 hours under nominal load (this varies depending on load, head, and conditions). 

Q5. What kind of engine does it use?
Answer: A Honda gasoline engine around 3.5 HP, air-cooled, running at ~3,600 rpm. 

Q6. What maintenance is required?
Answer: As above—regular oil and fuel checks, cleaning, inspecting impeller and seals, flushing after use, storing properly.

Is PG2A Right for You?

You should go with PG2A if:

• You need a compact pump with decent flow to handle relatively clean or mildly dirty water.

• Your job involves medium-sized dewatering tasks but not heavy solid content or sludge.

• Portability and ease of transport matter.

• You want solid reliability without stepping up to very large or expensive models.

You might consider moving up if:

• You often deal with trash, large debris, or heavy solids (use a PT series).

• You have extremely tall lifts or long discharge distances.

• You need more flow (volume per minute) for bigger sites.

Summary & Why the PG2A Is Valuable in 2025

The Wacker Neuson PG2A Dewatering Pump offers an excellent balance of flow, lift, durability, and portability for many standard water removal jobs. It’s ideal for contractors, renters, and municipal jobs where water needs to be removed quickly but conditions aren’t overly brutal. With its solid horsepower, reliable Honda engine, and wear-resistant components, it stands as a strong middle ground in the PG/PT lineup.

Used correctly—and maintained properly—it will give you efficient performance, fewer breakdowns, and a good return on investment.
