Challenges

Most industrial centrifugal pumps carry a significant capital equipment value. It is important to extend their service lives and ensure that they run efficiently. Proactive maintenance can reduce the risk of breakdowns and increase pump reliability and longevity.

Bearing Frame & Housing 

Bearing Frame & Housing

Challenge 1: Oil Leaks from Threaded Assemblies

The gaps between threads of drain plugs, oiler nipples, fittings etc. can lead to oil leaks due to constant pressure changes within the bearing housing. Not only do these leaks increase costs but also lead to the seizure of fittings and safety hazards.

Solution: Seal threaded assemblies with LOCTITE 567 Thread Sealant

Challenge 2: Bearing Spinout, Corrosion and Component Damage

Bearings are prone to spinning either on their shafts, or within their housings, resulting in damage to these parts regardless of whether they have been pressed, shrunk or slip fitted in place. The gap that exists between a bearing and shaft is an area where rust can form and cause damage to the parts.

Solution: Fit and seal bearings with LOCTITE 641 Bearing Retainer

Frame Adapter 

Frame Adapter

Challenge 1: Gasket Failure between Bearing Frame and Frame Adapter

Leaks from the frame connection can mean money lost in oil consumption and potential safety hazards. This happens because pre-cut gaskets cannot tackle the gap between flange surfaces. Flange imperfections are potential leak paths that pre-cut gaskets cannot seal and they relax over time to make the gaps large enough for leaks to happen.

Solution: Seal flanges with LOCTITE 518 Flange Sealant

Challenge 2: Fastener Loosening and Corrosion to Frame Adapter Mounting Bolts

Bolts are always under strain caused by torque, vibration, shock, thermal expansion and contraction. The gaps between the engaging nuts and bolts allow these external factors to challenge the clamp load.

Solution: Lock and seal bolts with LOCTITE 243 Threadlocker

Pump Casing 

Pump Casing

Challenge: Corrosion and Seizure of Pump Casing Bolts

The severe pump environments of constant temperature, pressure and humidity changes cause the pump casing bolts to corrode and seize. Seized casing bolts make pump maintenance difficult and create additional labor associated with drilling and tapping the bolt hole.

Solution: Seal and Protect Bolts with LOCTITE 243 Threadlocker

Challenge: Leaks between the Stuffing Box and Casing

The use of cut gaskets has inherent problems. Neither does it occupy all flange irregularities, nor does it maintain elasticity. This leads to creation of leak paths that corrode and damage the flange surfaces.

Solution: Seal flanges with LOCTITE 518 Flange Sealants

Coupling 

Coupling

Challenge: Misalignment and Damage Due to Coupling Loosening

Couplings are held in place by a key and a set screw. If the set screw loosens, the coupling can begin to slide along the shaft and disengage, or it can begin to wallow out the keyway.

Solution 1: Lock set screws in place with LOCTITE 222 Threadlocker (for > ¼") 
Solution 2: Lock set screws in place with LOCTITE 243 Threadlocker (for > ¼")

Pump Base Mounting 

Pump Base Mounting

Challenge: Misalignment Due to Loose Mounting Bolts

Vibration and possible impact shock can work to loosen the mounting bolts. Loose bolts result in a loss of clamp load, which allows the pump to lose its level and aligned configuration.

Solutions: Maintain alignment by securing mounting bolt with LOCTITE 263 Threadlocker
