These pages are for information. The section below headed maintenance is for your information but not as instructions to be followed by persons who are not qualified by training and certification from PulseGuard Inc, PulseGuard Ltd. PulseGuard China, PulseGuard India.

The PulseGuard pulse dampener products are for pressure purposes and may be dangerous. PulseGuard pulsation dampeners should therefore only be serviced / maintained by qualified personnel, appropriately certified, with current up to date certificates.

PulseGuard US UK India and China will rebuild, test, and re-pressure certify PulseGuard pulsation dampening equipment at the same price as the cost of a spares kit from the factory. If you do not have a local certified rebuild service facility, apart from the spares cost the only expenditure required of you is to pay for the shipping to your nearest PulseGuard certified point of assistance.
