Bi-directional Water Pump Seal JGT100

Bi-directional Water Pump Seal JGT100

The JGT100 is a bi-directional water pump seal that works in either rotation direction, so it can be fitted without setting a drive direction. Its single conical spring sits inside an elastomer bellows away from the pumped product, so this bi-directional water pump seal resists clogging and sticking even in dirty water. The balanced bellows design also gives the bi-directional water pump seal the benefits of a balanced mechanical seal on plain shafts, keeping a stable face load under changing pressure.

The JGT100 bi-directional water pump seal is a direct equivalent to the John Crane Type 1, with US and UK standard dimensions in metric or inch sizes. The square pin locks the seal face for safe, fracture free running, and faces can be carbon, silicon carbide, tungsten carbide or ceramic with NBR, EPDM or Viton secondary seals. Because it is bi-directional, one part covers both left hand and right hand pumps, which simplifies stock and speeds up pump maintenance. For water and waste water service, this bi-directional water pump seal keeps a leak proof seal even when the medium carries solids.

Technical Specifications

Applications

• Water pumps and waste water pumps
• Chemical and process pumps
• Mixers, blenders and agitators
• Air compressors, blowers and fans
• Pulp and paper, food processing and power generation equipment

Key Advantages

• Bi-directional design runs in either rotation direction with no set direction
• Single spring elastomer bellows keeps the spring away from the medium, so no clogging
• Balanced bellows gives balanced seal benefits on plain shafts
• Equivalent to John Crane Type 1 with US and UK standard dimensions
• Insensitive to solid containing and abrasive media for reliable water pump service

Frequently Asked Questions

Q1: What does bi-directional mean for this water pump seal?
A: The JGT100 bi-directional water pump seal can run clockwise or counter clockwise. There is no set rotation direction, so the same seal fits both left hand and right hand water pumps.

Q2: Does the JGT100 replace the John Crane Type 1?
A: Yes. The JGT100 is a John Crane Type 1 equivalent, also known as the JG T-100, with US and UK standard dimensions so it drops into the pump without modification.

Q3: Why does the bi-directional design resist clogging?
A: The single conical spring is enclosed in an elastomer bellows away from the medium, so solids in dirty water cannot jam the spring. This keeps the bi-directional water pump seal clean and stable.

Q4: What media does the JGT100 suit?
A: This bi-directional water pump seal handles water, oil and weakly corrosive media. For solid containing or abrasive water, the elastomer bellows design resists clogging and holds a leak proof seal.
