SCHEDULED MAINTENANCE
STRAINERS
Strainers must be cleaned regularly to avoid pump starvation.
Schedule will depend upon the application and conditions.
LUBRICATION
NOTICE:
To avoid possible entanglement in moving parts do not
lubricate the gear reducer or any other parts while the
pump is running
.
Sleeve bearings (bushings) are lubricated by the liquid being
pumped. Additional lubrication is not required.
IF EQUIPPED: Blackmer gear reducers are shipped from the
factory without oil in the gearcase. Fill with the grade of oil
indicated on the reducer tag. Change the oil after the first 48
hours of use and approximately every 500 hours of use
thereafter.
VANE REPLACEMENT
NOTICE:
Maintenance shall be performed by qualified technicians
only. Follow the appropriate procedures and warnings
as presented in manual.
1. Remove the head assembly and all other parts on the
outboard (non-driven) side of the pump. See the "Pump
Disassembly" Section.
2. Turn the shaft by hand until a vane (14) comes to the top
(12 o'clock) position of the rotor.
Figure 5 – Vane Replacement
3. Remove and replace the vane, making sure to install the
vane with the rounded edge outward to contact the
cylinder.
4. Rotate the shaft until the next rotor slot is in the top
position, and replace the vane.
5. Continue this procedure until all new vanes are in place.
6. Reassemble the pump as instructed in "Pump
Assembly."
