Thermal Fluid Pump Protection System​

PumpGuard thermal fluid pump protection system provides localized fire suppression and monitoring for thermal fluid pumps to protect your equipment, process, and people.

The most common cause of fire in thermal fluid systems is the degradation and failure of mechanical seals in thermal fluid pumps.

What would a plant fire cost you?

  • Personnel injury or death

  • Capital equipment loss

  • Production downtime

  • Extensive foam cleanup

Our PumpGuard fluid pump safety system adds layers of protection to reduce the risk of thermal fluid pump fires!


PumpGuard+​ Pump Safety Systems 

Wechsler Technologies' PumpGuard+ Fire Suppression System includes all of the features of the base PumpGuard package PLUS dual-zone fire suppression to both the mechanical seal AND the pump volute housing, providing total protection of the entire pump area.

Three Layers of Pump Protection

  • Forced air cooling to prolong seal life
    Dual guard housing (patent pending) directs fluid pump motor cooling air across the pump’s mechanical seal, reducing the seal’s operating temperature and prolonging its.

  • Preventive monitoring to predict possible failure
    Monitor key indicators of thermal fluid pu
    mp health including seal temperature, vibration, and leak detection, to detect early signs of oil pump failure before a fire occurs.

  • Active local fire suppression for ultimate protection
    Foam fire suppressant delivered via spray nozzle directly to the source of the fire - the pump, minimizing affected areas and required cleanup.

PumpGuard Thermal Oil Fire Suppression System Components

1. PumpGuard Base System

Complete, pre-engineered package including the dual guard housing for forced air cooling and fire containment, fire-sensing temperature switch, and active, localized fire suppression

2. PumpGuard +

Dual-zone fire suppression coverage to both the mechanical seal AND the volute housing, providing total protection of the entire pump area

3. Seal Protection Package

Monitor seal temperature and vibration to ensure pump health

4. Leak Detection System

Detect leaks due to seal wear and shutdown the pump on catastrophic failure

5. Multi-Point Monitoring System

Monitor all of the inputs from each PumpGuard System at a central HMI and transmit the inputs to the main PLC through a communications network

How Wechlser Technologies  Prevents Thermal Oil Fires


The video here provides a more detailed look at our PumpGuard systems, showcasing how they help prevent oil pump fires from occurring, and suppress fires when part failures occur. 

PumpGuard Safety Features


No other thermal oil pump protection system provides the level of coverage of benefits PumpGuard does. PumpGuard thermal oil pump safety system provides benefits including:


Preventative Measures

  • Active forced air cooling at the mechanical seal 

Early Failure Monitoring

  • Leak, temperature, and vibration monitoring

Failure Source Detection

  • Early leak detection at seal pump

Targeted Fire Suppression

  • Fire suppression directed at pump seals 

Reduced Downtime  

  • Faster recovery and cleanup in the case of part failure or fire incident
