Maintenance and service

Liquiflo FTS Transfer Pump User Manual
Series No. FTS400

47

1.

Ensure that all springs, wiper blades, and wear plates are properly installed on each rotating assembly before
installation.

2.

Grease the narrow ends of the shafts with Mobilgrease

XHP™ 222. This is to ensure the shaft seals in the center

plate do not hang up on the corners of each step on the shafts.

3.

Align the bearing holes of the center plate with the drive shafts and carefully lower the center plate over the shafts
until it contacts the pump lobe wear plates, 1. When pushing the center plate over the drive shafts, apply even and
steady pressure to ensure you do not damage the shaft seals during installation.
