Sempo SP-230 Marine Air Angle Grinder (IMPA 590303) Now in Stock at Tend Industrial Supplies USA

Tend Industrial Supplies is proud to announce the arrival of a highly requested marine-grade grinding solution — the Sempo SP-230 9-Inch Marine Air Angle Grinder (IMPA 590303).

This heavy-duty pneumatic vertical grinder is now available in our U.S. inventory and ready for fast domestic delivery.

For shipyards, offshore contractors, oil & gas maintenance teams, and heavy steel fabrication professionals, this arrival represents more than just a tool — it’s a dependable solution built specifically for harsh marine environments where electric grinders simply do not belong.

Engineered for Marine & Offshore Operations

The Sempo SP-230 is not a standard workshop grinder. It is built to meet IMPA Code 590303, the internationally recognized marine procurement code used by ship chandlers and vessel supply teams worldwide.

This makes it ideal for:

• Shipboard maintenance

• Offshore oil platform operations

• Dockyard repair facilities

• Engine room grinding

• Heavy marine descaling

• Structural steel grinding in wet environments

In marine operations, moisture, salt exposure, and confined hazardous areas create serious safety risks when using electric tools. The SP-230 eliminates those concerns with its fully pneumatic air-powered design.

Why Marine Teams Prefer Air-Powered Grinders

When working on vessels, docks, or offshore rigs, safety is non-negotiable.

The Sempo SP-230 operates entirely on compressed air, meaning:

• No electrocution risk in wet deck conditions

• Reduced ignition hazards near fuel vapors

• No electric motor overheating

• Safer performance in confined ship compartments

For U.S. shipyards and offshore contractors, this level of safety compliance is essential.

Controlled 6000 RPM High-Torque Performance

Unlike high-speed workshop grinders that run at 8,000–10,000 RPM, the Sempo SP-230 is governed at 6000 RPM.

That’s intentional.

Lower RPM combined with industrial torque delivers:

• Strong, aggressive rust removal

• Deep hull descaling capability

• Better grinding control

• Reduced kickback

• Longer abrasive disc life

• Less operator fatigue

This controlled power output makes it especially effective for thick corrosion removal and heavy weld grinding on marine steel.

Built for Harsh Conditions

Marine environments are unforgiving. Saltwater, humidity, vibration, and impact are part of the job.

The SP-230 features:

• Industrial all-metal housing

• Corrosion-resistant construction

• Heavy-duty vertical body design

• Dual-handle stability grip

• PVC auxiliary handle for comfort

At 4.3 kg, it provides balanced weight distribution for two-handed control during extended grinding sessions.

This is a grinder built for shipyard abuse — not light workshop use.

How It Compares to Standard Workshop Grinders

The SP-230 is purpose-built for environments where reliability matters most.
