FAQ
A1: Yes. The core installation interfaces match the original model, allowing a direct connection to existing equipment. If the equipment has special space restrictions, we can provide a dimension‑verification service to ensure a seamless replacement.
A2: The seal ring is made of metal‑impregnated retort carbon and is pressure‑treated. It resists corrosion from heat‑transfer oil up to 300 °C and offers excellent wear resistance. Under the rated working conditions it maintains a reliable sealing effect for a long period, thereby reducing the risk of leakage.
