If You Don't Hear It , It must be a Secoh Pump

Secoh pumps were designed to be compact and light by the motor and pump parts being combined in one single construction. The soundproof casing and the muffler integrated in the tank base reduce operating noise which makes Secoh pumps extremely quiet. The muffler along with the specially formed pump chambers, make the exhaust air flow practically pulsation-free. To achieve the lowest vibrations the pump casing is separated from the outer casing by vibration-isolating rubber. Operation is based upon the principle of electromagnetic oscillation, which eliminates the need for any sliding parts, thereby minimizing power consumption and providing a high degree of efficiency. The completely oil-free operation guarantees a dry and unadulterated air flow. The simple mechanism and very few construction parts guarantee a long and reliable period of operation.
