How to choose the correct seal kit for my hydraulic equipment?

First, confirm the equipment model (e.g., Hydralift Hydraracker sdprosperity, Catwalk Machine RR500-510 Gir) and the original seal kit part number. Second, check the hydraulic system’s working pressure, temperature, and oil type to ensure the seal material (NBR, FKM) is compatible. Our seal kits are matched to specific equipment models to avoid mismatch issues.

2

What are the key maintenance points for non-sparking plugs in hazardous locations?

First, only plug/unplug when the power is off to avoid sparks. Second, clean the plug and check the seal regularly to prevent dust and moisture entry. Third, avoid rough handling to prevent pin bending or shell damage. Fourth, use only non-sparking tools when installing or maintaining the plug to comply with NEC 500 standards.

3

How often should I replace the filter elements and why?

Air filter elements should be replaced every 6 months (cleaned monthly), oil filter elements every 3 months, and hydraulic filter elements when the pressure difference exceeds 0.1MPa. Regular replacement prevents clogging, which reduces system efficiency, causes component wear, and leads to equipment failure. This follows ISO 16232 standards for filtration system maintenance.
