The graphite shovel 70x45x5 is designed for dry-running rotary pumps with a groove size of 70x45x5 mm.
The graphite shovel 70x45x5 is designed for installation in dry rotary pumps with a groove size of 70x45x5 mm. The 70x45x5 mm graphite shovel is manufactured from a composite material based on graphite and a special fibre. This composition makes the plate less brittle and more resistant to wear.
To replace and lapping the graphite shovels: - remove the 3 bolts on the pump (5 mm hex);
- remove pump cover;
- replace the old plates with new ones, having cleaned the working part from dust and dirt;
- for lapping a sheet of abrasive paper 400 20x20 cm in size is needed. Cover the working part of the pump with it, press it against the pump cover and run the pump for 2-3 seconds. The vanes will rub down to the correct size and may need to be repeated if necessary;
- close pump cover, screw in place.
