3. Maintenance
3.1 General Maintenance
. Check periodically for product or air leakage. Tighten any joint where leakage is occuring.
. When pumping hazardous or toxic liquids, diaphragms should be replaced at regularly scheduled intervals based
upon pump usage.
3. When pumping highly abrasive fluids reduce discharge flow rate to prolong life of diaphragm, valve balls, valve
seats etc. or optionally use a larger pump which can be operated at a lower stroke frequency.
4. If you are pumping a fluid that will settle or compact the pump must be flushed before shut down.
5. In freezing temperatures, the pump must be completely drained when idle.
3.2 Maintenance Model 1/4"
3.2.1 Maintenance of Check Valve, Gasket and O-Ring
. Flush the pump to be certain all corrosive or hazardous materials are removed. Remove suction, discharge and
air supply lines.
. Remove the nuts (8) and slide the six cap screws (7) that hold the pump together out of the pump. Remove the
eight screws (5) and two screws (5A) from the left and right manifold plates (,9) and inspect the gaskets ().
The suction (or lower) check valves are an integral part of the left and right chambers and should not be dis-
mantled. If replacement of the valve seats is necessary, items (6) and (8) which contain the valves must be
replaced.
The upper discharge valve disks (3) are not sealed into the chambers and may be inspected for wear.
Caution!
Due to the distortion of gaskets under pressure, gaskets may need to be replaced after pump has been disas-
sembled to assure a positive seal.
3. To inspect manifold tube o-rings (7) remove right chamber (8).
4. Both diaphragms (9) can be inspected after removing the right and left chamber (6.8). If diaphragms appear
worn or ruptured go to step 7. If diaphragms do not need replacing, proceed with steps 5 and 6.
5. To reassemble: Insert the discharge valve disks (3) into place. Press gaskets () into groove in chambers (6, 8).
