Spring Maintenance Checklist for Industrial Operations

At Sunair, we've partnered with plant managers and maintenance engineers across chemical processing, petroleum refining, water treatment, and food production facilities for more than 50 years, learning that comprehensive spring maintenance (alongside regular industrial pump maintenance) is not an expense—but a strategic investment that delivers substantial returns.

We’ve put together this spring checklist to ensure your industrial operations remain smooth, avoiding costly downtime or compromised production quality. 

Key Takeaways

• Your post-winter assessment must address hidden damage to foundations, metal components, mechanical seals, and electrical systems before summer's increased operational demands begin.
• Proper pump maintenance requires verifying alignment, checking impeller clearance, examining casings for corrosion, and testing performance against baseline measurements, along with complete lubrication system renewal.
• Mechanical seals deserve your special attention during seasonal transitions—inspect seal faces, verify spring tension, and examine support systems to prevent costly leaks and downtime.
• Compressor systems need condensate drain cleaning, filter replacement, cooling system preparation, and control system verification to handle summer's humidity and temperature challenges.
• Thorough cooling system maintenance, including coil cleaning, refrigerant management, and water treatment helps improve ROI through improved efficiency, extended equipment life, and reduced emergency repairs.

Your Post-Winter Assessment Starts With Addressing Hidden Damage

Foundation Integrity Checks

Your spring maintenance must include a thorough inspection of:

• Visible cracks
• Mounting points
• Anchor bolt integrity
• Settlement indicators
• Potential water infiltration areas
• Laser alignment verification

Corrosion Remediation

Spring maintenance must include inspection of:

• All metal surfaces
• Pump casings
• Pipe joints
• Support structures exposed to winter conditions

Seal Integrity Verification

• Inspect all mechanical seals

Electrical System Inspection

• Open all enclosures
• Thermal imaging to identify hotspots
• Test insulation resistance

Going Beyond Basic Industrial Pump Maintenance & Inspection

Critical Spring Inspection Points

Verify Proper Alignment

• Verify all pump-to-motor alignments

Check Impeller Clearance

• Adjust the impeller clearance to manufacturer's specifications

Examine Casings

• Visual examination
• Ultrasonic thickness testing

Test Performance Against Baseline

• Measure flow rate
• Measure suction and discharge pressure
• Measure power consumption
• Record vibration signatures
• Capture temperature profiles
• Measure noise levels

Lubrication Requirements

• Complete oil change
• Verify proper viscosity
• Inspect automatic lubrication systems
• Lubricate bearings properly

Mechanical Seal Maintenance

Seal Faces

• Remove and inspect seal faces under magnification
• Look for irregularities

Spring Tension

• Verify spring tension

Environmental Controls

• Inspect all environmental control systems

Preparing Compressor Systems

Condensate Management

• Clean all traps and drains

Air Intake Systems

• Replace intake filters
• Inspect intake ducting
• Clean intake screens
• Verify pressure monitoring systems

Cooling System Preparation

• Clean heat exchanger surfaces
• Check for scale buildup
• Verify temperature control valves
• Inspect cooling fans
• Confirm airflow around air-cooled units
• Test thermal overload protection

Control System Verification

• Calibrate pressure and temperature sensors
• Test shutdown sequences
• Verify load/unload control settings
• Check sequence controls
• Confirm energy management system functionality
• Update firmware if necessary

Cooling System Final Checklist

• Coil cleaning
• Refrigerant leak detection and charge check
• Control system testing
• Water chemistry/treatment check
