Q: What is the material of the vanes in the PV7 series pumps?
A: The vanes are made of high-strength cast iron or phenolic resin composite materials, which have good wear resistance and self-lubriing properties to adapt to the high-speed sliding environment inside the pump.
Q: Can the PV7 series pump be driven by an electric motor or an internal combustion engine?
A: It can be driven by both; when driven by an internal combustion engine, a flexible coupling with good shock absorption performance should be used, and the engine speed should be stabilized to avoid excessive speed fluctuations affecting the pump's service life.
Q: What is the allowable radial load on the pump shaft of the PV7 series?
A: The allowable radial load is limited; refer to the product manual for specific values. Excessive radial load will cause bearing wear and shaft deflection, so avoid installing pulleys or gears directly on the pump shaft.
Q: How to deal with the problem of shaft seal leakage of PV7 series pumps?
A: First, check whether the shaft seal is worn or aged; if so, replace it in time. In addition, check whether the pump shaft has runout or the oil pressure is too high, and eliminate the root cause before reassembly.
Q: Does the PV7 series pump have a built-in filter?
A: Standard models do not have a built-in filter; it is necessary to configure suction filters, return filters, and high-pressure filters in the system according to the actual needs to ensure oil cleanliness.
