Pump Coupling Tensioners
Fast, Accurate, Safe & Cost Effective
Traditionally, installing and removing coupling flanges on tapered shafts has been accomplished by heating the flange or by using a jury–rigged assortment of mechanical jacks. These methods are time consuming and can be a safety hazard.
Fast:
The Pump Coupling Tensioner reduces a 12–hour chore to a 20–minute task. There is no need to wait for the coupling to heat up or cool down.
Accurate:
It has the power to accurately advance the coupling to its proper position on the shaft. There is no time–consuming rework associated with a mispositioned coupling.
Safe:
It is designed to fit the specific coupling. Controlled hydraulic pressure pulls the shaft and coupler together or pushed them apart. No heating is required.
Cost Effective:
It is reversible, so it performs both the assembly and the disassembly task. For most designs the hydraulic pressure is provided by a standard (10,000 psi) hand pump and hose. Higher operating pressures, up to 33,000 psi, are available.
Pump Coupling Tensioner Applications
- Condensate Booster Pump (CBP)
- Reactor Coolant Pump (RPC)
- Reactor Feed Pump (RFP)
- Reactor Recirculation Pump (RRP)
- Feedwater Pump
- Heater Drain Pump
- Steam Generator Feed Pump (Both Main & Auxiliary Pumps)
- Any Primary or Secondary Pump with a Tapered Shaft
- Any Piece of Rotating Equipment with a Tapered Shaft
Assembly
Thread the Pump Coupling Tensioner onto the tapered shaft. Connect the hose assembly and the hand pump, then increase the pressure to push the coupler flange to the desired location on the shaft.
Disassembly
Thread the opposite end of the Pump Coupling Tensioner onto the tapered shaft. Install the Backup Plate for the Tensioner to push against. Attach the hose assembly and the hand pump, then increase the pressure to push the flange off of the tapered shaft.
