5-c. INSTALLATION AND ELECTRICAL CONNECTIONS
Ansimag K Series pumps are easily inspected without removing the casing from any piping, by
separating the drive end from the wet-end. In a close-coupled pump this requires moving the motor,
drive magnet and bracket backwards and away from the casing. To be able to do this the motor must
have sufficient clearance behind the motor fan cover to move the motor backward approximately 6"
[150 mm]. Close-coupled installations should feature the following:
1. Allow at least 6" [150 mm] of clearance behind the motor.
2. The base plate under the motor must be flat and long enough to allow for safe movement of the
motor.
3. The motor electrical wiring should include a flexible section near the motor to allow movement of
6" for servicing of the pump without disconnecting piping. The recommended installation is
illustrated in Figure 5-3.

5-d. EARTHING
ARRANGEMENT
Pumps that have been supplied in accordance to the ATEX Directive (94/9/EC) will be identified by a label with
the following symbol on it:
Such units are supplied with an earthing ground lug that is attached by a M6 screw (60-70 in-lb) and a lock
washer (kit, P4107) to the bracket. Once the unit is installed and leveled, it should be wired to earth with a
suitable earthing cable.
