CH. 4 - MOTOR ASSEMBLY
K-SERIES, SCM 4 PLUS®, SCM 4 HF and SA 6 pumps are designed to be coupled with 4" motors (K-SERIES, SCM
4 PLUS®, SCM 4 HF and SA 6) and 6" motors (SA 6) in accordance with NEMA standards.
Perform the following operations to guarantee a correct coupling:
- remove the raceway that protects the cable and the sand-protection filter
- manually check the rotation of the motor shaft and the hydraulic unit
- verify that the coupling and the coupling axis are clean
- join the pump body and the motor, verifying that the electric cable is correctly positioned next to grooves on the
hydraulic unit supports
- tighten the nuts on the 4 motor tie rods, alternatively on the diagonals
- position the electric cable along the pump and reassemble the protection raceway by tightening the screws to the
hydraulic unit
- fix the sand protection filter to the lower support of the hydraulic unit body by using the screws provided for this
purpose
