Safely conveying additives in hazardous areas up to 60°C

In the petrochemical industry, various additives are mixed in from drums, for example to protect machine parts or to separate water from crude oil. Conveyance takes place in explosion-protected areas at temperatures up to 60 °C.

Solution
FP 424 / 425 Ex S drum pump and F 460 Ex commutator motor

Task

Retrieve various additives used in the petroleum industry from drums and add them to the process in measured doses. Among other things, these additives are used to protect machine parts or to separate water from crude oil. The system is used in explosion-proof areas at temperatures up to 60 °C.

Requirements
  • Use in hazardous areas (ATEX)  
  • Temperature-resistant up to 60 °C  
  • Suitable for low-viscosity media  
  • Safe drum emptying 
Solution in Detail

The FP 424 Ex S (HT) and FP 425 Ex S (HT) drum pumps, equipped with the F 460 Ex (HT) commutator motor, deliver additives directly from drums. The HT ATEX pump is designed for use in explosion-protected areas and at elevated temperatures.

Result

 

Safe use in potentially explosive atmospheres up to 60 °C

Seal-less pumping reduces wear and maintenance requirements

Nearly complete emptying of barrels (up to 99.98%) minimizes residual quantities

A check valve prevents the fluid from flowing back into empty drums

Reduced disposal and cleaning costs thanks to optimal residual emptying

Use in explosive atmospheres

The HT versions of the drum pumps are specially designed for use in explosion-protected areas. When combined with ATEX-compliant motors, they enable safe operation at ambient temperatures up to 60 °C.
