Procedure for greasing the IP55 version (MEC 160-180): in pumps produced with degree of
motor protection IP55 and in which the bearings greasing system is provided, the grease discharge
hole is closed by a brass cap M10x1 situated at an angle of 90° to the grease nipple. Unscrew and
remove the cap M10x1, apply grease to the grease nipple using a suitable grease pump, continuing
until clean grease comes out of the discharge hole. Switch on the pump and let it run for about an
hour so as to bring the bearing(s) to running heat and thus enable the excess grease to flow out.
Screw the cap M1x1 back in place.
