Most Common Reasons Pump Components Fail (And How Precision CNC Machined Parts Prevent Breakdowns)

Pump failures are one of the most expensive problems in fluid-handling industries. From corrosion to misalignment, even a tiny tolerance error can shut down entire systems. At Rajgranth Industries Pvt. Ltd., we manufacture high-precision CNC machined components for pump manufacturers worldwide— designed to eliminate these failure points completely.

Corrosion eats away pump parts from the inside, weakening the structure and causing leakage or complete breakdown.

Why It Happens

• Harsh chemicals
• Continuous exposure to water
• Poor grade stainless steel
• Contaminants in liquids

How Rajgranth Industries Fixes This

• High-grade Stainless Steel (SS316, SS304)
• Duplex & Super Duplex Materials
• Precision surface finishing

Misalignment between rotating pump parts increases vibration, friction, and energy loss—eventually causing bearing and shaft damage.

Common Causes

• Improper installation
• Low-quality connectors
• Off-center machining
• Wear over time

How Rajgranth Industries Prevents Misalignment

• Micron-level concentricity
• Perfect axial alignment
• Superior dimensional accuracy

Even a fraction of a millimeter inaccuracy can reduce pump efficiency, increase wear, and shorten lifespan.

Typical Problems

• Increased friction
• Uneven loading
• Low flow efficiency

How Rajgranth Industries Solves It

• CNC turning & milling with tight tolerances
• Precision-ground surfaces
• Accurate geometries for perfect fit

Cheap materials reduce pump life dramatically and often fail under pressure, heat, or chemical exposure.

Effects of Inferior Materials

• Quick wear
• Premature cracking
• Poor strength under load

Rajgranth Industries’ Material Excellence

• Stainless Steel
• Duplex Steel
• Super Duplex
• High-Strength Alloys
