ROTAN® ED (Magnetic Coupling) Series Gear Pumps

ROTAN

ED stands for Environmental Duty.

Because they require minimal maintenance, ED pumps offer a highly economical solution compared to conventional sealed pumps, especially in applications requiring double mechanical seals.

These types of applications typically have demanding operating conditions, resulting in frequent maintenance or replacement of the seal and support system. Therefore, the life cycle costs of ED pumps are generally much lower compared to pumps using double seals.
