Wilo BL 65/220-30/2 pump (art. No. 2786221)
A single-stage centrifugal pump with a block-type dry rotor for installation on a foundation. Block design with low noise and vibration with an intermediate housing and a fixed unified (standard) electric motor. With a bellows sliding mechanical seal with forced washing independent of the direction of rotation (with 37 kW/4-pole and 45 kW/2-pole, optionally with a cartridge mechanical seal in the Back-Pull-Out system to replace the sliding mechanical seal without dismantling the electric motor) and a cavitation-reducing impeller. The flanges have fittings R 1/8 for pressure measurement. A cataphoresis coating is applied to the pump housing and the intermediate housing. Serial electric motors with IE3 technology. Pumps with electric motors ≥ 5.5 kW are equipped with a thermal sensor to protect the electric motor.
