Fireproofing Equipment Repair in Sterling, VA: Keep Your SFRM Pumps Running

Don’t let a clogged pump kill your timeline.

In the world of commercial fireproofing, a downed pump isn’t just a mechanical failure—it’s a financial hemorrhage. When your crew is standing ready at a job site and your SFRM (Spray-applied Fire Resistive Material) isn’t moving, every minute is lost profit.

At Chandler & Sons Automotive, we understand the high-stakes world of passive fire protection. We don’t just “fix engines”; we specialize in the high-torque, heavy-wear machinery required for cementitious and intumescent fireproofing.

Frequently Asked Questions

How often should SFRM continuous mixers be serviced?

Continuous mixers should undergo a deep-clean and mechanical inspection every 50–100 hours of operation. Because cementitious fireproofing is highly abrasive, seals and mixing paddles wear significantly faster than in standard mortar applications.

Why is my piston pump losing pressure during fireproofing?

Loss of pressure is usually caused by worn packings, damaged ball seats, or a failing hydraulic motor. In SFRM applications, the abrasive nature of the material can score the piston rod, leading to rapid pressure drops.
