In a centrifugal end suction pump, the bearings are the primary components that support the rotating shaft and ensure the impeller remains perfectly centered within the volute. Due to the high speeds and continuous operation required in HVAC and industrial cooling, bearings eventually succumb to wear, heat, and moisture. EKG (Malaysia) Sdn Bhd provides specialized End Suction Pump Bearing Replacement services, using precision extraction tools and high-grade components to restore silent, vibration-free operation to your pumping system.
Audible Grinding or Screeching – High-pitched metal-on-metal sounds indicate the bearing races are pitted or lubrication has failed.
Excessive Housing Temperature – Bearings that are too hot to touch often signal internal friction or "over-greasing" issues.
High Vibration Levels – Worn bearings allow the shaft to "wobble," causing vibrations that can damage mechanical seals and couplings.
Metal Filings in Lubricant – For oil-lubricated pumps, the presence of metal flakes is a sign of imminent bearing seizure.
Increased Amp Draw – The motor works harder to overcome the mechanical resistance of a failing bearing, leading to higher energy costs.
Before dismantling, we measure the current vibration velocity and bearing housing temperature to confirm the extent of the damage and identify any underlying misalignment.
Using hydraulic pullers and specialized bearing splitters, we remove the worn bearings without scoring or damaging the pump shaft. We avoid "hammering" techniques that can lead to shaft bending or internal stress.
We perform a micrometer check of the shaft journals and the bearing housing (seat). If the tolerances are out of spec (due to a bearing spinning on the shaft), we provide metal spraying or machining services to restore the correct fit.
We supply and install premium-grade bearings (such as SKF, FAG, or NSK) specifically rated for the RPM and load of your pump. We offer:
Sealed-for-life bearings for maintenance-free operation in standard HVAC loops.
Open bearings with grease zerk fittings for industrial pumps requiring periodic lubrication.
To ensure a perfect interference fit, we use Induction Heaters to expand the new bearings before sliding them onto the shaft. This "shrink-fit" method prevents the mechanical damage associated with cold-pressing bearings.
Once the pump is reassembled, we perform Laser Shaft Alignment between the pump and motor. This is a critical step; even the best bearings will fail prematurely if the pump is misaligned by as little as a few microns.
Precision Overpowering Force – We use the right tools for the job, ensuring your pump shaft remains true and undamaged.
ISO-Certified Technical Team – Our procedures meet international standards for mechanical assembly and safety.
Rapid Turnaround in Selangor – We understand that your cooling system cannot be down for long; we offer efficient on-site or workshop services.
Comprehensive Warranty – We stand behind our work with guarantees on both parts and labor.
Don't let a noisy bearing lead to a seized motor or a snapped shaft. Trust EKG (Malaysia) Sdn Bhd for precision end suction pump bearing replacement. Our expert team will ensure your pumps run quietly, efficiently, and reliably for years to come.
