Advantages:
The small seal for increased pressure. The BT-PN is a mechanical seal with a simple but effective design for mass-produced pumps. The special spring arrangement allows a short axial installation length. This advantage is combined with an increased working pressure capability and because the spring is free from torque transmission.
