Rolling pump

What is Rolling Pump?

We call diaphragm-micro pumps as "Rolling Pump".
Rolling pumps include three types of pump, air pumps, vacuum pumps, and liquid pumps.
Every type has variety of model, and they surely will satisfy your requirements.

Mechanism of rolling pump

Rolling pump organization chart
Rolling pumps contain multiple diaphragm-driven cylinders 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 valves ) enables silent operation, with which the noise level is maintained low from no-load to mazimum pressure conditions.
Liquid pump
   These pumps feature excellent suction performance (3mAq) and forcing performance (40mAq).
