9 PUMP INSTALLATION
9.1 Installation
The pump must be xed horizontally using the M16x1.5
threaded support feet. Tighten the screws with a torque of
210Nm.
The base must be perfectly at and rigid enough as not
to allow bending or misalignment on the pump coupling
axis/transmission due to torque transmitted during operation.
The unit cannot be xed rigidly to the oor but must
interposed with vibration dampers.
For special applications contact the Technical or Customer
Service Departments.
A lifting bracket is mounted on the pump for easy installation,
as per the gure below.
