Rolling pumps contain multiple diaphragms to minimize the pulsation, noiseless operation, long life, and high pressure.
This mechanism is an achievement of OKEN SEIKO's unique design and development technology.
Mechanism of rolling pumps is simple and easy to implement using multiple cylinders per motor .
This is the reason that our rolling pumps feature space saving and high flow .
In addition, this structure also reduces the motor torque variation and thereby minimizes pulsation.
These pumps feature very high flow and high compression pressure (80 to 120 kPa ) compared to their sizes.
Their discharge valve construction (hat valve) enables silent operation, with which the noise level is maintained low from no-load to maximum pressure conditions.
