BODY AND MANIFOLD DRAINING
Suction and delivery valve ball lifters may be fitted to F Series Slim Style metallic pumps as an option
where rapid pump draining is required.
On pumps fitted with this option there are external levers for operating the suction and delivery valve balls.
The levers must be turned to the “run” position for normal use and turned to the “drain” position to lift
the valve balls only when the pump is not running.
The valve ball lifter spindles are each retained with a securing nut which should remain tightened to a
torque of 3 Nm (2.2 lb/ft ) to prevent leakage. A second nut on each spindle is provided to secure the
operating lever and should also be tightened to a torque of 3 Nm (2.2 lb/ft).
