FAQs
Q: Are the pumps resistant to strong acids and alkalis?
A: The PTFE-coated diaphragm and FKM valves provide good resistance to a wide range of moderately corrosive gases. They are NOT recommended for strong acids (e.g. HF, concentrated H₂SO₄) or strong alkalis. Contact us for chemical compatibility guidance.
Q: Do the pumps require oil or regular maintenance?
A: No. All C-Series pumps are diaphragm-driven and completely oil-free — no lubricant, no oil changes, and no oil mist. Maintenance requirements are minimal.
Q: What is the thermal protection device?
A: Every C-Series motor includes a built-in thermal cut-off that automatically shuts the pump down if it overheats, then resumes operation once the motor has cooled to a safe temperature.
Q: Is a 220V/50Hz version available?
A: Yes. All models are available in both 110V/60Hz and 220V/50Hz versions. Contact Hi Pro Science to confirm your preferred voltage variant.
