3000 RPM diesel engines for fire-pump enquiries, with a published 20–150 kW range. Request the exact model’s shaft-power rating, pump compatibility and approved operating conditions.
The gallery shows several configurations. Request current model-specific photographs, data sheets and a complete quotation for your project.
Alexerpower / Weifang Junwei Machinery Co., Ltd lists a 3000 RPM diesel engine range for fire-pump enquiries with a published 20–150 kW power range. This is a range description rather than a data sheet for one engine model. Request the exact model, approved shaft-power rating at the proposed speed and pump-drive configuration before selection.
The original listing describes the engines as Isuzu/Yanmar copy-type engines. Request the actual manufacturer, exact model and nameplate; that wording does not establish genuine-brand manufacture or brand authorization. The gallery illustrates several engine configurations, so request current photographs of the quoted engine.
These reference data are reorganized from the existing Alexerpower listing. Confirm the selected engine’s data sheet, rating conditions, installation requirements and agreed scope of supply.
| Item | Listing reference and confirmation needed |
|---|---|
| Product scope | Diesel engine range offered for fire-pump enquiries; confirm the exact engine and package |
| Published power range | 20–150 kW; request model-by-model shaft-power ratings at the proposed speed |
| Listed engine speed | 3000 rpm; confirm the selected engine rating and pump operating speed |
| Manufacturer identity | Original Isuzu/Yanmar copy-type description; confirm the actual manufacturer, model and nameplate |
| Rating basis and duty | Not defined by the range alone; request approved engine rating conditions and permitted operating duty |
| Radiator reference | 40°C maximum stated; confirm cooling performance for site temperature and pump-room ventilation |
| Fan arrangement | Belt-driven fan with safety guard in the listing; confirm the supplied cooling package |
| Charging equipment | 12 V or 24 V reference; confirm which voltage and complete starting/charging system are supplied |
| Filtration | Dry-type air filter, fuel filter and oil filter listed; confirm the supplied components and maintenance instructions |
| Listed options | Fuel tank, belt pulley/PTO shaft and automatic controller; confirm compatibility, specifications and inclusion |
The listing does not provide a verified model-to-power schedule, fuel-consumption curve, torque curve, dimensions or model-specific fire-service approval documents. Request these for the proposed engine. Engine shaft power is different from generator electrical output and pump hydraulic output.
Provide the pump performance curve, required operating speed and maximum absorbed shaft power across the required operating range. Have the proposed engine’s available power assessed for the site altitude, temperature and drive arrangement using that engine’s approved data.
Clarke’s fire-pump engine selection guidance explains general factors such as pump maximum power, engine/pump speed, altitude, cooling, ventilation and exhaust. It is background guidance for selection, not evidence of this range’s specifications or approvals; use the supplied engine’s own documents.
The 20–150 kW figure describes the published range, not one engine’s adjustable output or a verified rating for every model. Request the exact model’s approved shaft power at the proposed speed, rating conditions and duty. Match that available power to the pump’s absorbed-power curve and site conditions.
The original description says Isuzu/Yanmar copy-type engines. It does not establish manufacture or authorization by either brand. Confirm the actual manufacturer, complete model, nameplate, current photographs, data sheet and applicable warranty for the engine being quoted.
The current product information does not establish model-specific UL Listing, FM Approval or an NFPA 20 project compliance assessment. If your project requires them, request verifiable listing or approval details for the exact model, speed and rating, and documentation for the complete installation and control package. A 3000 rpm label or generic quality-system statement is not proof of fire-service approval.
They are listed as options. Request a quotation and bill of materials specifying the actual fuel tank, drive interface, controller, starting system and cooling package. Confirm controller compatibility and any project-required approvals rather than assuming a complete fire-pump package is included.
Suitability depends on the selected pump’s speed, absorbed power, drive arrangement and the proposed engine’s approved rating and site limits. The listing has no verified hourly fuel curve. Request model-specific consumption at the relevant load points with fuel and test conditions; do not use another engine’s fuel figures for this package.
Request written warranty terms with a clear start date, time and running-hour limits, coverage and exclusions. Ask for operating and maintenance manuals, test documentation, the agreed spare-parts list and destination service arrangements. Current quality-system or emissions claims require documents for the actual manufacturer and supplied model.
Request the exact engine model and power schedule rather than choosing solely from a range label or gallery image.
Contact Alexerpower with your pump curve and project requirements. Request current manufacturer and model details, power/torque and fuel data, installation drawings, current photographs, applicable approval evidence and a complete quotation.
