Product information "Standard block 25/160"

The block design enables high circulation rates with little space requirement. The motor can be replaced without having to completely disassemble the pump or remove the mechanical seal. The highly wear-resistant bellows mechanical seal is independent of the direction of rotation and maintenance-free. This is also lubricated by the medium via an internal circulation line and enables a long service life. The pump shaft made of stainless steel 1.4571 is additionally protected by a shaft protection sleeve also made of stainless steel 1.4571. This prevents wear on the pump shaft. Directly mounted, low-noise, surface-cooled, replaceable DIN IEC three-phase standard motor in German brand quality. Energy efficiency class IE3 from 0.55 KW, including PTC sensor with fixed bearing on the pump side. The motors are manufactured ex works with sealed condensation drain holes.
