Maintenance of a Pump Head Without Seal Wash Option
1
Place the pump head on a flat surface. Loosen the lock
screw (two turns) and while holding the lower half of the
assembly (piston housing) carefully pull the pump
housing away from the piston housing.
2 Remove the support rings from the piston housing and lift
the housing away from the pistons.
3 Check the piston surface and remove any deposits or
layers. Cleaning can be done with alcohol or tooth paste.
Replace piston if scratched.
4 Using the steel side of the insert tool carefully remove the
seal from the pump housing. Remove wear retainers, if
still present.
