ROTAN ED Internal Gear Pump

ROTAN ED Internal Gear Pump

Magnetically coupled internal gear pump for ultimate protection against leakage

ED is for Environmental Duty. As only minimal maintenance is necessary, ED pumps will be a very economical solution compared with traditionally sealed pumps, especially where the application requires the use of double mechanical shaft seals.

Often these applications are very arduous resulting in the seals and support system requiring regular attention and/or replacement. Thus, the life cycle costs for ED pumps are generally much lower than for pumps using two seals.
