Orbray develop and manufacture compact diaphragm pumps equipped with an in-house motors.
Based on our high-efficiency motor, we offer a diaphragm-type li quid pump and an air pump that are compact, lightweight, and highly corrosion resistant. Stable self-sufficiency and flow characteristics are realized by our patented check valve structure that is low noise and maintenance-free.
Features
- Lightweight & Compact
- Long life, high chemical resistance
- Maintenance-free
- Oil-free
- Low noise
- Check valve structure
- No priming required
Principle and Mechanism
- The rotational motion of the motor is converted into a linear motion of the diaphragm using an eccentric crank.
- Pressure changes in the pump chamber are generated with the vertical movement of the diaphragm.
- With the pressure change in the pump chamber, the check valve opens and closes to generate a flow.
