For maintenance of diaphragms, first remove the suction line of the
pump and than block the pump discharge line.Cut off the compressed
air supplybleed thepressure from the pump and disconnectthe air
supply line from the pump. Drainany remaining liquid from the
pump.Inspect the pump assembly drawings and maintenance
diagrams.Remove the manifolds.Remove the pump ball and ball
seats.Then remove the outer covers of the pump.
*First: Removal of diaphragm assemblies
Use M16 wrench or socket to unscrew the outer diaphragm holder by
turning counterclockwise direction and remove the diaphragm
assembly from thediaphragmrod.Then take onediaphragm together
with outer and inner diaphragm holders and the otherdiaphragm with
its diaphragm rod out.In order to disassembly first diaphragm with its
holder, hold the diaphragm assembly with a vice by clamping the
inner holder and remove the outer holder by turning it
counterclockwise with M16 spanner.
Hold the diaphragm rod of other diaphragm assembly with a vice and
dismantle diaphragm with a spanner.Perform dismantling the other
diaphragm in the same manner.Check the diaphragm for cuts,
bursting, abrasion and chemical corrosion.Replace the diaphragms
as necessary.
*Second: Installing diaphragms
Insert M16 capscrews onto the outer diaphragm holder and push the
diaphragm into the center hole. Install the capscrews onto inner
diaphragm holder and screw it onto the rod by turning clockwise.Hold
loose assembly with a vice.Screw M16 wrench with a spanner.
*Third: Installing diaphragm assembly onto pump
Make sure the bumper is installed over the diaphragm rod. Screw the
rod of the diaphragm assembly by turning clockwise into threaded
hole until it is in the same direction with the end of the inner
diaphragm plate. Insert rod into pump.Bring the capscrew holes on
the diaphragm in line with inner chamber capscrew holes.Install outer
chamber onto the pump by capscrews and ring nuts.
On the opposite side of the pump,pull the diaphragm rod out as far
aspossible. Make sure the second bumperis installed over the
diaphragm rod.Screw the exposed part of the diaphragm assembly
shaft in clockwise direction onto the diaphragm rod as much as
possible and leave the gap sufficient enough to adjust the capscrew
holes on the diaphragm in line with inner casing capscrew holes.
Install the part of outer casing onto the pump with capscrews, nuts
and washers. Install the manifolds onto the pump with capscrews,
nuts and washers. Perform the necessary connections onto the
pump. Now the pump is ready for the operation.
