That "F Class" on your pump's nameplate? It matters more than you think 🌡️⚙️
Insulation class tells you the max winding temperature before the motor's insulation breaks down:
A: 105°C · B: 130°C · F: 155°C · H: 180°C
Vriha motors use Class F insulation — today's industrial standard.
Why it matters: every 10°C over rating roughly halves insulation life. More thermal margin means a longer-lasting, more reliable motor.
