Common failures & inspection points

Shaft alignment and runout deviation exceeding tolerance

Check coupling alignment with dial indicator after installation and weekly during operation; axial/radial deviation must not exceed 0.25 mm (0.010 inch); recheck after one week of operation

Screw clearance wear and gear backlash deterioration

Check axial clearance of shafts (max 0.2 mm / 0.0080 inch) and timing gear clearance (max 0.5 mm / 0.0020 inch); replace timing gears if clearance exceeded; inspect screw shafts and cylinders for damage

Cavitation risk and NPSH margin inadequacy

Verify inlet pressure and flow characteristics; confirm low NPSH requirements are maintained (Houttuin pumps designed for <0.5 bar NPSH); monitor for cavitation noise/vibration indicating suction line issues

Mechanical seal leakage and cooling/lubrication failure

Inspect seal chamber for weeping or stream leaks; verify cooling lines patent if integral cooling present; check seal API Plan (90/Plan 2 for pressurized sealing); monitor gearbox oil level and condition for timely lubrication of timing gears

Excessive vibration from bearing wear or misalignment

Measure overall vibration (ISO 10816); confirm major misalignment will cause shorter coupling/bearing life and vibration spikes; inspect bearings (internal or external) for noise and play; replace if vibration levels abnormal
