Mounting the diaphragm
Place the same number of U-washers ( 9 ) on the connecting
rod as were there previously. Make sure that no
U-washers (
9 ) fall into the pump housing.
Screw in the diaphragm ( 8 ).
By lightly pressing on the diaphragm push the ridge on the
underside of the diaphragm into the groove of the housing.
Mounting the valve plates
Insert the “dust free” valve plates (

( 7 ), making sure they are in the correct position.
Assembling the pump head

The method of assembly will depend on the pump type. For
this reason, please proceed with the section that corresponds
to the pump type you are using (
NF 1.100 version or NF

Insert the resonating diaphragm ( 4 ) in the connecting plate ( 5 )
and cover with the head plate ( 2 ) fitted with a new O-ring ( 3 ).
The positions of the intermediate plate ( 7 ), the connecting plate
( 5 ) and the head plate ( 2 ) are determined by the 3 locators
(head screw elements).
Insert the four head screws ( 1 ) in the through holes of the
pump head.
Make sure that the flow direction of the pump head (see direc-
tional arrow on the head plate ( 2 )) is the same as previously.
Place the pump head onto the pump housing and alternately
tighten the four head screws ( 1 ). The maximum tightening
torque is 1.5 Nm.
