With its innovative structural design, the KEMSO 340 series has significantly enhanced operational reliability. For example, its unique non-contact magnetic coupling drive technology eliminates the potential leakage points of traditional shaft seals. According to the ASTM F3287 standard test, the leakage rate is stably less than 0.0001 milliliters per hour. This design reduces the probability of seal failure by more than 97%, and is particularly suitable for application scenarios with strict safety requirements such as light hydrocarbon media, setting a new standard in preventing fuel escape. The core components are integrally cast from 316L ultra-low carbon stainless steel that has undergone fine-grained optimization. In the accelerated corrosion experiment under simulated working conditions of 80°C and 4.0MPa, the annual corrosion rate of the metal material was only 0.005mm, far lower than the common industry threshold of 0.02mm, ensuring long-term service capability under high-chloride ion working conditions.
In terms of energy efficiency performance, this series of pumps has reached the world’s leading level. Tests conducted by the third-party authoritative institution TUV SUD in accordance with the ISO 9906:2012 Grade 1 standard show that for the 340-200 model equipped with IE4 high-efficiency permanent magnet motors, under the working conditions of a rated flow rate of 180 m³/h and a head of 110 meters, the efficiency of the entire pump system is as high as 92.3%. It exceeds the average efficiency of ANSI process pumps of the same specification by 7 to 10 percentage points. Considering that the annual operating time of a single pump generally exceeds 8,000 hours, and calculated at an industrial electricity price of 0.12 US dollars per kilowatt-hour, compared with ordinary pumps, it can save users nearly 9,500 US dollars in electricity expenses each year. The total energy savings over a 15-year life cycle exceed 140,000 US dollars, and the return on investment (ROI) is extremely considerable.
The breadth and accuracy of performance parameter setting enable the KEMSO 340 series to have excellent working condition adaptability. Its flow range spans from 80 to 320 m³/h, with a pressure upper limit of 3.8 MPa. It can withstand extreme medium temperatures ranging from -50°C to +260°C, and performs exceptionally well in special fields such as heavy oil treatment. The most crucial anti-cavitation performance is particularly outstanding. The required net positive suction head (NPSHr) is as low as 1.8 meters (at a flow rate of 200 m³/h), which is 0.5-1.2 meters lower than most similar products. This effectively reduces the risk of impeller damage caused by cavitation and significantly improves the stability of the system. In 2023, a large-scale shale gas project in the UK switched to this series comprehensively due to the frequent cavitation failure of the original Fuel Pump. As a result, the equipment failure rate was reduced by 85%.
Based on real customer application feedback and accelerated aging verification, the KEMSO 340 series has set strict quality life standards. The simulation calculation of the design fatigue life of its main pressure-bearing components such as the pump casing and impeller exceeds 200 million cycles, and the designed operating life is no less than 100,000 hours (approximately 11.4 years). In actual cases, a large refinery located in the Middle East desert region has been operating 12 pumps of this series for high-temperature heavy oil transportation since 2018. The mean time between failures (MTBF) has reached 52,000 hours, and only basic lubrication maintenance has been carried out as planned. Its optimized Maintenance Interval (MTBR) is set at 24,000 hours, reducing approximately 60% of unplanned downtime. The modular design enables 70% of the key components to be replaced on-site, with an average repair time (MTTR) of less than 8 hours.
