The Wacker Neuson HMS KIT-M2500-SM3S-H35HA (5100018044) is a premium electric internal concrete vibrator kit built for maximum productivity, versatility, and durability in demanding consolidation applications. Combining a powerful 2.5 HP (1.8 kW) M2500 electric motor, a 10-foot reinforced SM3S flexible shaft, and an H35HA 1-3/8" hybrid head, this modular setup is engineered for professional concrete contractors, rental fleets, and civil construction teams requiring high-frequency performance and lasting jobsite reliability.

Product Overview: Modular Compaction That Raises Industry Standards

This complete HMS kit is purpose-built for contemporary concrete placement—

• The M2500 double-insulated universal motor delivers 16,000 RPM, producing vigorous, deep, and even compaction through even the heaviest pours or toughest mixes.

• The included 10' SM3S shaft offers the ideal reach for most columns, footings, and slab work, while the rugged construction ensures flexibility and wear resistance.

• The 1-3/8" (35mm) H35HA hybrid vibrator head is induction hardened for maximum durability and engineered for high amplitude, optimizing consolidation of low, medium, and high slump mixes with minimal surface defects.

Technical Specifications

Performance & Reliability Features

High-Efficiency, High-Frequency Compaction

• 16,000 VPM quickly targets air pockets and consolidates aggregate for denser, stronger, and more fully bonded slabs, walls, columns, and decks.

• Consistent RPM, even under heavy load, means uniform results and fewer jobsite reworks.

Maintenance-Friendly & Durable Build

• Long-life carbon brushes (up to 500 hours) and easy external access promote low downtime and quick field service.

• Reinforced protection hose and hardened vibrator head minimize damage from tough concrete mixes and abrasive aggregate.

Modular Flexibility for Every Job

• Quick-release, tool-free shaft couplings mean you can swap in longer/shorter shafts or different heads to adapt to project needs without dedicated tool downtime.

• System is compatible with the full HMS range (1.5–30 ft. shafts / 1–2.75" heads), further future-proofing your investment.

Operator Comfort and Jobsite Safety

• Damped vibrations and lightweight component parts help reduce operator fatigue, even during extended consolidation sessions.

• Safety-focused double insulation, splash resistance, and rugged construction meet the demands and challenges of modern jobsites.

Application Scope & Best Fit Projects

The KIT-M2500-SM3S-H35HA is especially effective for:

• Structural concrete: Fast, consistent compaction of beams, columns, walls, and footings—even in dense rebar mats or congested formwork.

• Slab-on-grade: Quickly moves and settles aggregate to minimize honeycombing and bug holes.

• Bridge decks, piers, and civil infrastructure: Extended shaft reach and high vibration make it ideal for large, deep pours or heavily reinforced structures.

• Tilt-wall, precast, and architectural forms: Delivers smooth finishes required for exposed concrete and specialty designs.

Real-World Reviews & User Experience

Concrete pros routinely praise this HMS kit for:

• Effortless startup and "remarkable consolidation"—often outperforming gas-powered alternatives in both speed and uniformity.

• Consistent, repeatable finish quality—fewer callbacks and reduced patch/repair work post-pour.

• Light weight and intuitive quick-release couplers significantly simplify transport and switchovers, especially when working across multiple forms in a day.

• "Lasted way way more than 500 hrs" according to field reviews; rugged, low-maintenance design that's "the best vibe I've ever owned."
