Clarke Fire understands that not every installation is the same. Whether you’re working at high altitude, in marine environments, or places with high humidity or dust, Clarke’s engine options are designed to adapt. For instance, stainless-steel instrument panels or corrosion-resistant cooling systems ensure durability—even in the most demanding settings.
Their engineering team is dedicated to providing purpose-built solutions—ranging from advanced starting systems to comprehensive monitoring packages—to address the unique challenges of each use case.
From the site, Clarke groups its customizable additions into the following categories—each enhancing a specific aspect of the engine’s reliability or functionality:
Clarke provides both a standard paint finish and a more durable epoxy coating—offered through downloadable product brochures.
Stainless-steel components, such as instrument panels, are offered for environments where corrosion resistance is critical—protecting electronics and instruments in coastal or chemical-exposed installations.
Clarke pioneered innovative features such as UL-listed pneumatic starting systems—especially suitable for rapid deployment needs. Additionally, sound-attenuated enclosures and exhaust silencers can be specified to minimize noise in installations where passengers or staff are nearby.
Engine packages can include comprehensive instrumentation—gauge readouts, alarm systems (covering fuel, oil, temperature, etc.), and digital displays housed in rugged or NEMA 4X-rated enclosures.
For marine environments or highly corrosive conditions, Clarke offers sea-water-compatible cooling loops and weatherproof, sound-attenuating enclosures.

It reframes these options around their practical importance, and positions Excel Industrial Service as the expert local provider integrating Clarke solutions in Pakistan.

Clarke Fire’s maintenance kits are thoughtfully crafted solutions that help ensure diesel fire pump engines remain dependable and compliant. Built around a two-year service cycle, these kits simplify the tasks recommended by NFPA 25, the standard guiding inspection, testing, and maintenance of water-based fire protection systems.
The first tier of Clarke’s maintenance strategy is the Annual Maintenance Kit. It includes the essential filter components needed yearly:
These items help keep your engine clean, fuel-efficient, and protected from corrosion.
The Second-Year Supplemental Kit is tailored to address wear and coolant system needs and contains:
This ensures continuity of care, especially for parts subject to wear or heat-related strain.
Clarke organizes maintenance kits by engine model. For a given model—identified by its serial number and purchase data—you can request either the annual kit or the supplemental kit. Some kits come in stock, while others are made to order.
For instance, heat exchanger-cooled engines like the JU4H, JU6H, JW6H, DT2H, and C18H0 series each have dedicated BOM (Bill of Materials) kit numbers associated with them. If the supplemental kit isn’t immediately available, Clarke can work with you directly to ensure you get the right parts.
Using only Clarke-certified parts is vital for safeguarding system performance and longevity. Unauthorized or counterfeit parts can compromise engine function, possibly void warranties, and tragically, undermine fire safety.
Every Clarke engine carries a laser-engraved nameplate with a unique QR code. Scanning it directs you to a secure page on ClarkeFire.com where you can verify details like model, serial number, rating, and access useful documentation such as manuals, startup checklists, and maintenance kit info.
Clarke provides a generous warranty: standard coverage for two years from commissioning (or 18 months post-shipment). But here’s the bonus: if maintenance is performed per NFPA 25 guidelines, you automatically receive an additional third year—no added cost, no fine print.
To order the correct maintenance kit, you’ll need:
These details help Clarke confirm the right BOM part number, especially for Supplemental Kits that vary by production run or configuration.
Need help figuring out which kit fits your engine? Clarke’s customer support is equipped to assist—via email or phone—and can even guide you to purchase parts individually if a full kit isn’t ideal.
