②The outlet pressure must always be higher than the inlet pressure.

Model Code

Installation and Use

1. During installation, the concentricity tolerance between the pump shaft and the motor must be less than 0.10mm (TIR), the maximum allowable angular error must be less than 0.2 degrees, and a flexible coupling must be used; the pump shaft must not bear radial and axial loads; the bracket must be strong and rigid, and able to fully absorb vibration.

2. Set the suction pressure of the pump inlet port: The recommended inlet pressure is 0 to 35 Kpa.

3. The oil should be kept clean, and the pipelines and oil tank must be thoroughly cleaned; the cleanliness of the oil should be within NSA12.

4. Normal pump operation (under rated conditions) is based on the use of SAE10W oil (or equivalent viscosity) within the range of 38℃ to 82℃.

5. Check the inlet, outlet and rotation direction before starting the pump. After fixing the pump, manually rotate the pump shaft evenly and flexibly. During the first startup, if the pump does not pump water immediately, air should be discharged from the pump's delivery pipeline.

6. During the first use, the pump body and oil suction pipe should be filled with oil, and the pump should not run without oil.

7. Do not start the pump when the outlet pressure is lower than the inlet pressure. This will cause operating noise and blade instability.

8. Cold start conditions: When operating SAE10W oil, the viscosity is in the range of 860 to 40 cSt, and the speed and pressure should be limited to 50% or less of their respective rated values until the system warms up. When the fluid viscosity is greater than 860 cSt, extreme caution must be exercised when starting the equipment, and attention should be paid to heating the entire system, including remote cylinders and motors.

9. At high temperatures, the viscosity should not be lower than 13cSt, and the temperature should not exceed 99℃, because the expected life of the cartridge air bag and elastomer will be reduced.
