GENERAL DESCRIPTION
For all Berarma pumps equipped with the through shaft option for the construction of multiple pumps (option “.03.“), the coupling units described below are available which allow to combine the following secondary pumps on the same axis:
- Berarma pumps
- pumps with ISO 3019-2 4 holes flange and cylindrical shaft
- pumps with rectangular flange and tapered shaft (like external gear pumps)
- pumps with SAE flange and cylindrical shaft
- other flange and/or shaft types could be manufactured on request
The ordering code for a combined pump should be specified according to coupling sequence:
- primary pump code (with option “A”) +
- coupling unit code +
- secondary pump code
To install a coupling unit, the following instructions must be observed:
- from the primary pump (1) unscrew the screws (2) which will not be reassembled
- from the primary pump (1) remove the cover (3) and its seal (4) which will not be reassembled
- from the primary pump (1), only for 01 PHP 05 pumps, remove the spacer ring (5) which will not be reassembled
- mount the coupling unit (6) paying attention to the seals to avoid oil leaks
- Note: Primary pump drain fluid will fill the coupling bell
- mount the secondary pump (7)
