Product Description

1. Product Overview
7421 Series micro rolling pump is developed by Keyto independently. It is mainly used in medical equipment, environmental protection equipment, instrumentation, mechanical chemicals, household electrical, laboratory and other high-end fields.
1.1  Characteristics Of 7421 Series Rolling Pump
The principal of rolling pump is the elastic diaphragm reciprocating by centrifugal wheel rotating, to change the volume of chamber, the valve body is central symmetric structure, with three working units inside, each unit can complete an average working cycle every spin. The main material of the pump body is PP, and the diaphragm material is EPDM.  
Characteristics:

1. Compact product structure, small size, large flow;
2. Good dynamic balance, small vibration, low noise;
3. The use of brushless motor, long lifetime, maintenance free;
4. Pump body material is compatible with a variety of working media;
5. High Output pressure
