What types of hydraulic oil are compatible with PV7 series pumps?
It is compatible with mineral-based hydraulic oils, synthetic hydraulic oils, and biodegradable hydraulic oils that meet the requirements of ISO 6743-4 (egory HM, HV, HG). The recommended viscosity range is 10-40 mm²/s at operating temperature.
How to select the appropriate displacement model of PV7 series pumps?
Select according to the system's required flow rate and working pressure. The displacement range of PV7 series is 4-180 cm³/rev; calculate the flow rate via the formula: Flow (L/min) = Displacement (cm³/rev) × Speed (rpm) ÷ 1000, and match it with the system's actual flow demand.
Can the PV7 series pumps be operated in both clockwise and counterclockwise directions?
Most standard PV7 models are designed for fixed rotational direction, but customized models with reversible rotation are available upon request; confirm the rotation direction requirements with the supplier before purchase.
What is the recommended oil temperature range for PV7 series pumps during operation?
The optimal operating oil temperature is 40-60 °C; the allowable short-term maximum temperature should not exceed 80 °C, and the minimum temperature should not be lower than 10 °C to avoid viscosity abnormalities affecting performance.
What causes abnormal noise during the operation of PV7 series pumps?
Common causes include insufficient oil suction (such as clogged suction filters, too-small suction pipe diameters), air mixed in the hydraulic oil, excessive oil viscosity, worn pump internal components, or loose mounting bolts.
