Type 311
Convincing Arguments! In its wide range of cartridge mechanical seals DEPAC also offers a series of O-ring, rolled bellows and welded bellows seals with 1/4" NPT flush and quench connections integrated in the gland. All designs can be supplied optionally with "DEPAC Standard Gland Versions" or for "Large Stuffing Box Diameters". The investment casting method is used for this series. It not only produces glands with a high-quality surface but is also extremely cost-effective, as is reflected in the attractive price for the end customer. Notes Some particularly small pumps come with very small SB cross-sections. The D1dimension requires special attention therefore. The distance D1, D3 to the SB diameter should be no less than approx. 1mm (0.039") in radius if at all possible. |
