Wacker Neuson PG3A Dewatering Pump

For contractors, landscapers, and jobsite managers, keeping work areas dry is essential. Water in trenches, foundations, basements, and around construction zones not only slows progress but can also damage materials and equipment. The Wacker Neuson PG3A Dewatering Pump is designed to solve that problem: a rugged, high-capacity pump ideal for clearing clean or lightly debris-laden water quickly and reliably.

In this guide, you’ll learn everything about the PG3A — its technical specifications, key features, use cases, maintenance, and how it stacks up against alternatives — to help you decide if it’s the right pump for your needs.

What is the Wacker Neuson PG3A?

The PG3A is a self-priming, centrifugal dewatering pump. That means it can quickly remove water from job sites using centrifugal force, and it’s capable of priming itself (i.e. starting to pump without needing a manual fill or auxiliary device). This pump is part of Wacker Neuson’s PG series, designed for clean or slightly dirty water (not heavy solids), with compact design but solid performance.

Technical Specifications

Spec Value
Suction & Discharge Diameter 3 in (≈ 75 mm) 
Max Flow Rate 264 US GPM (≈ 1,000 L/min) 
Max Discharge / Delivery Head 98.4 ft (≈ 30 m) 
Max Suction Lift 25 ft (≈ 7.5 m) 
Max Solids Size 0.25 in (≈ 6.5 mm) 
Engine Type Gasoline, air-cooled single-cylinder (Honda for PG3A) 
Engine Displacement ~ 9.9 in³ (≈ 163 cc) 
Max Rated Power ≈ 4.8-5.5 hp (≈ 3.6-4.1 kW) depending on variant 
Operating Speed ~ 3,600 rpm 
Fuel Tank Capacity ~ 3.8 US qt (≈ 3.6-4 L) 
Operating / Running Weight ~ 68-69 lb (≈ 31 kg) 
Dimensions (L × W × H) ~ 20.2-20.3 × 15.9-16 × 18.1-18.2 in (≈ 515 × 405 × 460 mm) 

Key Features & Design Highlights

  • Self-Priming Centrifugal Pumping Action: You don’t need additional priming equipment; the PG3A is built to draw in water and get started quickly. 

  • Cast-Iron Impeller and Volute: These parts are wear-resistant for longevity, especially useful in continuous use or outdoor conditions. 

  • Pump-Out Vanes Behind Impeller: These help reduce debris accumulation, which decreases clogging and maintenance downtime. 

  • Carbon-Ceramic Mechanical Seal with a low-oil shutdown feature: Enhances durability and protects engine in low lubrication scenarios. 

  • Lightweight Aluminum Housing & Protective Heavy-Duty Frame: Makes transport easier and adds structural protection, plus handles for carrying. 

Advantages & Benefits

  1. High Flow Rate with Compact Footprint
    You get around 264 GPM with a relatively light (≈ 69 lb) pump, making it powerful without being overly bulky. Excellent for contractors moving large volumes quickly.

  2. Reliable for Clean or Slightly Dirty Water
    Perfect for dewatering job sites, pools, foundations, or clear run-off water. The PG3A is not intended primarily for heavy solids or sludge.

  3. Durability Reduces Cost & Downtime
    Components like the cast iron impeller, volute, and mechanical seal help extend the pump’s life, reducing frequent replacements or service.

  4. Ease of Use
    Self-priming action, protective frame, clear carry handles, plus engine features like low-oil shutdown make it more user-friendly in rugged applications.

  5. Fuel Efficiency & Operating Duration
    With a tank of ~3.8 US qt and consumption in line with similar pumps, it provides a decent run time (~2.1 hours under full load) for many applications. tmsequip.com+1

Applications & Ideal Use Cases

  • Construction Sites: Draining water from foundation excavations, trenches, vaults.

  • Swimming Pools, Ponds & Landscaping: Removing water during maintenance or rain-storms.

  • Municipal & Utility Work: Clearing water from vaults, catch basins, storm drains.

  • Flood Response: Although for cleaner water, fast deployment helps in emergency drainage.

  • General Jobsite Water Removal: Anywhere clean or lightly dirty water must be moved efficiently.

How the PG3A Compares to Other Pumps

Factor PG3A Strengths When Another Pump Might Be Better
Solids Size Handling Up to ~0.25-0.30 in solids, good for small debris. For large trash or sludge (e.g., mud, heavy solids), get a trash pump model like PT-series.
Head & Lift ~98 ft max head, ~25 ft suction lift — solid for many vertical / horizontal setups. If you need higher lift or high vertical discharge, might need a larger pump or staged pumping.
Flow Rate ~264 GPM, excellent for clean water. If flow needed is lower but portability or electric power is required, look at smaller PG models or electric alternatives.
Portability Good: at ~69 lb, with frame and handles. If extremely mobile or lighter weight required, a smaller or portable electric version could be more appropriate.

Maintenance Tips

  • Regularly inspect the mechanical seal & impeller: Clean off debris after use; inspect for wear.

  • Check oil and fuel levels before starting; low oil shut-off helps prevent damage.

  • Flush the pump housing after use to prevent buildup of sediment or scale.

  • Inspect hoses and connections to ensure no leaks that reduce performance.

  • Store properly in dry, sheltered space when not in use; drain fuel if stored long periods.

Common Questions (FAQs)

Q: Can the PG3A pump heavy solids or sludge?
A: No, the PG3A is designed for clean water or lightly dirty water with solids up to ~0.25 in. For heavy solids or trash, a trash-pump variant (PT series) is better.

Q: How tall of a lift can it provide?
A: Max discharge height is ~ 98 ft; suction lift (vertical from water source to pump inlet) is up to ~25 ft.

Q: What fuel and engine does it use?
A: It uses a 4-cycle gasoline engine (Honda for PG3A version), ~9.9 in³ (≈ 163 cc), running at ~3,600 rpm.

Q: Is it easy to transport?
A: Yes — at ~ 68-69 lb, with carry handles and protective frame; manageable by two people or mechanical assist.

Q: How long can it run?
A: With ~3.8 US qt fuel tank, typical runtime is ~2.1 hours under full load. Real-life will vary depending on head, flow, and load.

Is the PG3A Right for You?

You should consider the PG3A if:

  • You need a high-capacity dewatering pump for clean or lightly dirty water.

  • Your job demands frequent water removal but not heavy sludge or debris.

  • You value durability, ease of maintenance, and extended service life.

  • You have hoses and discharge lines sized for 3-inch connections.

  • Portability is important, but you can manage ~70 lb with frame handles.

Avoid it or choose an alternative if:

  • Your water has a lot of debris, mud, or trash.

  • You need electric power (no gasoline / generator) or lower noise.

  • You require extremely high head (much more vertical height) or very small clearance.

Summary – Why the PG3A Stands Out

The Wacker Neuson PG3A Dewatering Pump offers a compelling combination of high flow, durable design, and clean-water capacity. With specs like 264 GPM, 98 ft discharge, 0.25 in solids capacity, and an efficient gasoline engine, it’s a top performer for many dewatering applications. Its durable components, lightweight frame, and self-priming functionality make it reliable, easy to use, and low-maintenance.

For contractors, site supervisors, municipal workers, or anyone needing dependable water removal, PG3A is one of the best clean/dewater pumps in its class in 2025.
