Why Silvan Selecta BP 20/15 Power Pump does not reach correct pressure?
- JjosephmorrisAug 7, 2025
If your Silvan Selecta Power Pump isn't reaching the correct pressure, several factors could be responsible. First, ensure the pump is operating at its full 540 rpm. Other potential causes include a blocked suction filter, a suction filter stop valve that's partly closed, or a pressure regulator that isn't correctly adjusted. The pressure regulator valve and seats could also be worn, or the pressure gauge might be faulty. Finally, check for ruptured pump diaphragms, indicated by grey or milky pump oil.
