In June of 2024, we SMC exported one diesel oil centrifugal pump for Sri Lanka, this is a horizontal double suction split case pump with capacity of 450 m3/h at 50m head and it is diesel engine drive, the centrifugal pump is used to transfer diesel oil from tank to vessel through 2000 m length pipe by Sri Lanka Ports Authority. After calculated pipe friction loss based on pump installation and performance requirements, we proposed and quoted suitable centrifugal pump for this application. The customers visited us for witness testing and checked pump actual capacity, head, speed, noise, shaft power, vibration and bearing temperature parameters, found all data are in accordance with requirements. As industrial pump provider, not only equipment, but also we are good at technical calculation and consulting relating to pumping system.
