The pump housings of the WITA® heating circulation pumps are equipped with a standard cataphoresis coating, which is intended to prevent oxygen deposits and thus corrosion. As a standard feature, WITA offers this process not only for solar pumps, but also for circulation pumps.
In addition, all WITA® high-efficiency pumps are equipped with an anti-block function in comparison to conventional standard pumps.
The electric motor produces slight shaking movements during start-up. A blockage of the pump after the summer break is thus almost excluded.
