Leak Proof Balanced Mechanical Seal C45B

The C45B is a leak proof balanced mechanical seal built to stop product loss on hard working industrial pumps. A balanced multi spring structure holds the faces evenly loaded, so the leak proof balanced mechanical seal keeps a tight seal even when pressure and shaft movement change. Because it is a balanced mechanical seal, face pressure stays low, friction heat drops and the faces wear slowly, which keeps the leak proof performance steady from one shutdown to the next.

Each C45B leak proof balanced mechanical seal is pressure tested before shipment, and a flexible O ring secondary seal absorbs vibration and misalignment, so the seal stays leak proof on heavy duty water, oil and chemical pumps. The compact single end face design fits standard cavities, and faces in carbon, silicon carbide or tungsten carbide can be matched to the medium. With a leak proof balanced mechanical seal in place, maintenance teams see fewer drips, less product waste and longer pump uptime. The C45B is available in both metric and inch shaft sizes, so it fits a wide range of imported and domestic pumps with no cavity change.

Frequently Asked Questions

Q1: How does the C45B stay leak proof?
A: The C45B is a balanced multi spring mechanical seal. Even face loading plus a flexible O ring secondary seal keeps the faces closed, so this balanced mechanical seal stays leak proof under changing pressure and shaft movement.

Q2: Is the C45B a balanced mechanical seal?
A: Yes. The C45B is a balanced mechanical seal, so face pressure stays low and heat build up is reduced, which helps the leak proof seal last longer on heavy duty industrial pumps.

Q3: Which media can this leak proof balanced mechanical seal handle?
A: It handles water, oil and weakly corrosive chemical media. For stronger chemicals, choose silicon carbide or tungsten carbide faces with an FKM O ring.

Q4: How is the seal shipped and what is the MOQ?
A: Each leak proof balanced mechanical seal is packed in a white box with a shock-proof foam insert and an export carton. MOQ is 1 piece, and delivery is normally 3 to 10 working days.
