The standard “multi-purpose” grease (consistent class NLGI-2) is suitable for temperatures up to
120°C.
For higher temperatures the standard grease should be replaced by a high temperature grease
(consistent class NLGI-3). This grease is, depending on the make, suitable for temperatures up to
150°C or 180°C.
When a pump will be applied in a system or under conditions facing extremely high or low
temperatures, the selection of the proper lubricant and correct lubrication interval should be
made in consideration with your grease supplier.
Do not mix different grades, different makes of grease together. Such a mix can cause severe
damage. Consult your local grease supplier.
Relubrication
• Starting with pump size TG H6-40, the ball bearings require lubrication through the grease
nipple every 5000 running hours or every 12 months (which occurs first).
• Add a correct grade of grease (see 3.21.3.5). Do not overfill (see table below).
The ball bearing type 2RS are grease filled for life and need not to be relubricated.
Both ranges ISO 3000 range and American AFBMA 5000 range are possible and have the
same built in dimensions.
• When the anti-friction bearing has been relubricated 4 times it needs to be cleaned.
Replace the old grease with new one or renew the anti-friction bearings.
• In the case of high temperatures, anti-friction bearings must be relubricated every 500 to 1000
running hours:
- when using grease of NLGI-2 class: for service temperatures > 90°C
- when using grease of NLGI-3 class: for service temperatures > 120°C
• When the load is extremely high, in case the grease looses much oil, anti-friction bearings
need relubrication after each peak service. We recommend relubricating while the pump is still
operating but after the peak load has occurred.
3.21.3.6 Sleeve bearings
We recommend checking the pump regularly for wear on the gear wheels and sleeve bearings to
avoid excessive wear of other parts.
• A quick check can be done by using the front pull-out and
back pull-out system. See table for maximum allowable
radial clearance of the sleeve bearings.
• For replacement of the sleeve bearings contact your local
supplier.
