RV type screw pump is a special structural pump designed according to American standards, specifically designed for small flow liquid transfer systems. In addition to its general structural working characteristics, it also has

Advantages of RV type screw pump:
The axial size is small, 1/3-1/2 shorter than the general structure of the pump, and the pump tends to be miniaturized.
Low temperature impact and low working torque.
Strong self-priming ability, up to 7-8m, with stable flow even at very low speeds. Usually used as a metering and dosing pump.
Low energy consumption, suitable for making micro pumps, even 40W motors can work normally.
In the RV series product models, 0.4, 0.8, and 1.5 represent flow rates of 0.4 liters, 0.8 liters, and 1.5 liters per minute at 0MPa and 400r/min. The latter number 3 represents an in stage pump that can generate a working pressure of 1.6-1.8MPa.
Similarly, the first number in 3.2, 6.2, and 12.2 indicates that at 0MPa and 400r/min, its flow rate is 3 liters, 6 liters, and 12 liters per minute, while the second number 2 represents a two-stage pump that can generate a working pressure of 1.0-1.2MPa.
