The former, as the name suggests, operates without mechanical seals, which are typically used in sealed pumps to prevent fluid from leaking.
While sealed pumps have served various industries for decades, seal-less pumps have been gaining traction due to their numerous benefits.
Here are some of the key advantages of seal-less pumps over their sealed counterparts and why industries are increasingly favouring them.
Understanding the fundamentals
Before delving into the benefits, it is important to understand the fundamental difference between sealed and seal-less pumps.
Sealed pumps use mechanical seals to contain the pumped fluid and prevent leaks. These seals require constant monitoring, maintenance and eventual replacement.
Seal-less pumps, on the other hand, do not use mechanical seals. Instead, they rely on magnetic couplings or canned motor designs to eliminate the need for seals entirely, thereby offering a leak-free pumping solution.
