Packing Seal Fire Pump

The initial cost of gland pump packing is low when compared to the costs associated with mechanical seal.

Packing seal fire pump. Mechanical seals in these pumps could fail during operation thus reducing the output. Choose from soft and rigid compression seal fittings that can be used with abrasive slurries food mixtures steam and hot sludges. Flexible graphite pump packing is prone to particle transfer in reciprocating pumps which will coat the length of a pump rod removing flexable graphite from the seal area and permit leakage. Packing is used in fire pumps because these are critical pumps that need to operate when they need to operate.

This is why pump packing is the primary source of packing for fire pumps and other applications that can t risk catastrophic failure. We also offer kits from patterson and fair banks please contact us with your pump information for purchasing. A mechanical seal and more specifically a double mechanical seal should always be used when the pumped fluid presents a safety health or environmental hazard. If it is a centrifugal pump nfpa 20 has no requirements on the type of seal.

If it is a positive displacement pump nfpa 20 prohibits the use of packing and only permits either a mechanical or a lip seal. Compression packing seals 552 products look to grainger for a wide range of compression seals to help form pressure tight bonds between pumping equipment and component parts. Fire pump packing pump packing pump packing adjustment pump packing application pump packing cutter pump packing definition pump packing gland pump packing g. Whereas mechanical seal failure can necessitate the shutdown of the pump.

Packing cannot be 100 leak free. Even when leakage isn t visible harmful vapors could be escaping. This is also true for single mechanical seals. Chemical resistant packing seals also known as 100 gfo these expanded ptfe seals contain graphite powder which dissipates heat away from the shaft and allows pumps to run cool at high speeds.

Why use a mechanical seal. Repacking and regular maintenance is import for protecting your building as well as preventing expensive repairs later.
