• Ret the clamping plate making sure the rounded outside edge faces the diaphragm, also ensure that the
outer sealing edge of the diaphragm is located securely in the grooves between the body and gear housing
(failure to do this will cause the pump NOT to prime).
• Ret clamping rings and tighten screws.
To inspect or replace the tricuspid valve(s), unscrew either or both housings to expose the valve(s). If a valve shows
signs of wear or damage, replace and re-assemble housings ensuring that the valves and diaphragm remain correctly
seated.
