What advantages do V-twin KB690 and KB750 engines have?
The twin-cylinder design creates extremely low vibration with large displacement and high power. Adopting forced pressure lubrication, they maintain stable performance under long-term full-load operation.
How long of raw material inventory does the factory maintain?
Core engine spare parts are stocked for 2 months as safety inventory to avoid production delays caused by raw material shortages.
Does the factory have an independent loading platform for containers?
We own a dedicated cargo loading platform where 20GP and 40HQ containers can dock directly, saving inland transportation costs.
Is the factory fully compliant with environmental protection standards with complete waste gas and wastewater treatment facilities?
Our painting and machining workshops are equipped with full waste gas & wastewater processing systems. We pass all annual environmental audits without environmental risks during customs or third-party factory audits.
What’s the function of the "National Brand Preferred Unit for Internal Combustion Engines" certificate?
It can be used as qualification certification for overseas supermarket and government bidding projects, enhancing product credibility and winning extra points in tender evaluation.
Can overseas customers benefit from preferential prices thanks to our High-tech Enterprise status?
R&D costs are shared internally to lower factory prices. Our emission-compliant products have better cost control compared with competitors with the same configuration.
Do all finished machines undergo full-load aging test after production? How long is the test duration?
Every finished machine must complete a 30-minute full-load aging test after assembly. High-power generators and water pumps are tested for 60 minutes. Defective products are reworked and never packed for shipment.
Are all product molds self-developed or purchased externally?
Core molds for engine cylinder blocks, motor housings and pump bodies are all self-owned. Standard general parts are purchased, while exclusive appearance molds for OEM orders require separate development.
What are the differences in flow and lift among 2/3/4-inch water pumps? How to select the right size?
40mm (1.5 inch): mini model for household garden irrigation;50mm (2 inch): high lift for smallholder vegetable plots;80mm (3 inch): balanced flow and lift for general farmland;100/150/200mm (4-inch and above): large flow for flood drainage.All models feature a standard 6-meter self-priming depth.
How to distinguish clean water pumps, sewage pumps, chemical pumps and high-lift pumps?
① KP standard clean water pumps (2/3/4 inch): for farmland irrigation and fish pond water circulation;
② KPT trash pumps & KPS sludge pumps: capable of pumping sand and debris;
③ KPY chemical pumps: corrosion-resistant pump body for chemical liquid transfer;
④ KPH high-lift pumps: maximum lift of 120 meters for long-distance water delivery in mountainous areas.
