  • Page 19: Repairs

    If the pump liquid temperature is above 80 ℃, high-temperature grease is recommended, e.g. SKF LGHP2. DESMI use SKF LGHP2 as standard. Vibration levels higher than 7 mm/s at pump bearing are considered damaging and will normally result in significantly shorter grease and/or bearing life – especially for pumps not running. Hence shorter re- greasing intervals might be required for pumps installed where external excited vibration levels can be higher than 7 mm/s.

The test pressure is stated in the test certificate and stamped into the discharge flange of the pump. ____________________________________________________________________________________ DESMI Pumping Technology A/S Tagholm 1 9400 Nø rresundby – Denmark...
