Canned Motor Pumps with explosion protection for hazardous explosive areas
Canned Motor Pumps with explosion protection are used wherever flammable or potentially explosive media need to be pumped safely – for example, in the chemical, petrochemical or energy industries. They are suitable for numerous standard applications where leak-tightness, operational safety and availability are crucial.
Thanks to their modular design / construction, Canned Motor Pumps can be flexibly configured and adapted to the specific process requirements. Different design variants allow for a precisely tailored selection depending on the fluid, temperature range and area of application – ensuring maximum safety and efficiency during operation.
