REASSEMBLY
Screw on the inner primary diaphragm to the thrust tube, which is still in the vice, push on the
separator disc and then the large ‘O’ ring, ensuring that the air vent grooves are positioned inwards
towards the back face of the primary diaphragm. Now push in the seal retainer. Position the
separator ring over the assembly to locate in the back bead of the primary diaphragm, ensuring
that this bead seal (integral with the diaphragm), is located into the recess provided on the ring.
Now screw on the back diaphragm ensuring that the PTFE white face is inwards.
If difficulty is experienced fitting the diaphragm, ‘flex’ the unit by immersing in hot, (but not boiling),
water for a few minutes. Under no circumstances should this diaphragm be fitted with the PTFE
(white) side facing outwards. Ensure that the connection tapping on the separator ring is in the correct
position for the Flotronic Sentinel Alarm System, or your own pressure switch if required/fitted.
All Pumps with 10” diameter diaphragms
Place the entire twin pack assembly into pump body and then open appropriate tool number B000,
B100 or B100H (B9000 Chemflo Pumps) fully, and grip around the assembly by clamping the tool
onto pump body rim (see sketch). Locate tool centre peg into the thrust tube hole showing at the
back of the diaphragm, and the screw down tool until diaphragms have been pushed through, the
first diaphragm of the opposite chamber, do not force the diaphragms through further than necessary
as this will shorten diaphragm life. Note that for the F Series ‘K’ Style Chemflo pumps the frame is
attached to the housing clamp bolt positions.
