FAQ
▔▔Q1: What does the "1B" mean in the PVS-1B-22N1-12 model code?
A: The "1B" indicates the frame size and the specific type of control mechanism-in this case, a standard pressure compensator type. It allows the pump to automatically reduce its output flow when the system hits the pre-set pressure limit.
Q2: Can the Nachi PVS-1B-22N1-12 pump rotate counter-clockwise?
A: No, the standard PVS-1B-22N1-12 model is designed for clockwise (CW) rotation only when viewed from the shaft end. Running the pump in the wrong direction can cause severe internal damage.
