Pump Coupling Tensioners
Hydraulics Technology offers hydraulic pump coupling tensioners to help you with your application in a way that is cost effective, fast, safe, and accurate.
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.
Benefits of Pump Coupling Tensioners
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.
Hydraulic pump coupling tensioners have the power to accurately advance the coupling to its proper position on the shaft. There is no time–consuming rework associated with a mispositioned pump coupling tensioner.
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.
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
Hydraulic Pump Coupling 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.
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.
