Inside the pressure area, situation with vaccum applications/ dry pumping mediums we can select double mechanical seals with external coolent or with barrier liquid. Many types of double mechanical seals are available. Cartridge type double mechancial seals also available
Double Mechanical Seal: Double Mechanical Seals are generally used for following circumstances · very dry medium · vacuum applications · higher temperatures · sludge with higher impurities or hard particles With above circumstance we must use double mechanical seal with external cooling provision. In this double mechanical seal assembly setting is more complicate for layman, so we always recommend double mechanical seal with cartridge assembly which is very much easy to assemble for layman.

35mm Double Mechanical Seal With SS Shinifit Stationary
A double mechanical seal is a type of mechanical seal with two primary seals or sets of faces, it can operate in various arrangements with a) a barrier (containment) between the sets of faces or b) a buffer (mixing).The inboard, or “primary seal” keeps the product contained within the pump housing. The outboard, or “secondary seal” prevents the flush liquid from leaking into the atmosphere. Two rotating seal rings are arranged facing away from each other.
Secondary end seal for Grundfos pumps Multi Spring O-Ring, Balanced, Upper Seal, in Oil. Grundfos, Spare, shaft seal seals for the following combinations of shaft diameters: 32 mm / 38 mm 38 mm / 50 mm 50 mm / 65 mm 65 mm / 65 mm Temperature: -30 ° ~ 200 ° Pressure: ≤2.5MPa Speed: ≤15m / s Materials (edit) Moving part: SIC Stationary ring: SIC Bellows: VITON Spring: SS304 / SS316 Metal parts: SS304 / SS316
conical spring doubleseal with O-Ring as a secondary sealing device. These seals are dependent on the direction of rotation, as the torque transmission is done by single conical spring. The direction of rotation is seen from the drive end of the shaft. Right handed springs are provided for the clockwise rotating shaft, and left-handed spring is provided for anti-clockwise rotating shafts. This seal can be easily assembled and dismantled as it consists very few parts. Due to its compact design, no axial or radial extra space is required for installation. These seals are designed to handle contaminated liquids, hence spring clogging does not occur. Application:
Water Pump Circulation
Pump Chemical Process Pump
Sewage & Submersible Pump
Seal Face: Carbon, Ceramic, Silicon, Tungsten Carbide
A double mechanical seal consists of two seals arranged in a series. The inboard, or “primary seal” keeps the product contained within the pump housing. The outboard, or “secondary seal” prevents the flush liquid from leaking into the atmosphere. Two rotating seal rings are arranged facing away from each other..
