The KLD Engineering Advantage

Engineered Solutions for Common Flygt Failure Points

We analyze common OEM component failures and engineer targeted upgrades. See how our parts solve the problems that lead to downtime.

Component	Common OEM Failure Points	The KLD Engineered Solution
Impellers	Rapid wear in corrosive + abrasive media Pitting from chemical attack Brittle fracturing from solids impact Efficiency loss due to vane erosion	CD4MCuN Duplex Steel construction Simultaneous resistance to corrosion & abrasion High toughness absorbs impact energy Maintains hydraulic profile for longer
Casings (Volutes)	Erosion of the cutwater, reducing efficiency Internal pitting leading to pressure loss Wear that increases impeller clearance	Cast in highly durable, erosion-resistant alloys Maintains hydraulic geometry for peak efficiency Extends the operational life of the entire wet end
Wear Rings	Soft material wears quickly, increasing recirculation Corrosion opens clearances, slashing efficiency Frequent replacement required to restore performance	Machined from hardened stainless steel alloys Resists both abrasive wear and chemical corrosion Maintains tight tolerances for sustained efficiency
Shafts	Corrosion under the sleeve or at seal locations Fatigue failure from high torque cycles Bending (runout) leading to seal and bearing failure	Machined from high-tensile strength stainless steel Superior resistance to fatigue and corrosion Ground to precise tolerances to eliminate vibration

Product Spotlight: Flygt Impeller 6495901 Upgrade

Specifically engineered for the workhorse Flygt 2600 series dewatering pumps (e.g., Flygt 2660), the KLD aftermarket 6495901 impeller is a direct upgrade for high-wear applications. Found in the toughest dewatering jobs in mining, tunneling, and construction, this impeller often fails when faced with both corrosive water and abrasive solids. Our version is the definitive solution.
