Hydraulic Hand Pump Specific Safety Considerations
Sealweld Products are designed for industrial use only and the Hydraulic Hand Pump should only be used by a
Certified Valve Technician
who is familiar with the working principals, mechanical limitations & working
pressures of the valve being serviced. When working with pressurized valves & lines use extreme caution and do
not take risks or short cuts. Always have a proper size stabbing valve ready in case of a valve fittings failure.
When working with valves in a toxic or low O
2
deficient environment,
ALWAYS
wear a self contained breathing
apparatus and have backup safety watch standing by. Use extreme caution before opening a body vent fitting.
ALWAYS
consult the Valve Manufactures manual prior to commencing work on any valve. Do not exceed
working pressure of valve when filling the body cavity.
NOTE:
Keep injection pressure below 27580 kpa (4000
psi) on cast iron or semi steel valves.
CAUTION:
Never hit the Giant Buttonhead Coupler #17G with hammer or other object to attach or remove the
coupler from a fitting. Doing so may result in damage to the fitting which could cause serious personal injury or
death.
WARNING:
In the event where the internal checks in the valve under service fail, it will be very difficult or
impossible to remove the Giant Buttonhead Coupler #17G. Ensure that you have all the proper tools, procedures
& product readily available should this problem arise.
DANGER:
Product may push back into Sealant Barrel #3
contaminating the Hydraulic Hand Pump.
NEVER
leave a contaminant in the Sealant Barrel #3 of the Hydraulic
Hand Pump.
NEVER
operate a pump
without a properly functioning pressure gauge or if the gauge shows signs of over
pressurization and is in poor operating condition.
The Internal Safety Relief Valve #8
is set to 68950 kPa (10,000
psi). The gauge should never exceed 75843 kPa (11,000 PSI).
ALWAYS
leave By-Pass Valve #7 open and the Sealant Barrel #3 fully loaded when not in use. See
“Storing
the Hydraulic Hand Pump”
on page twenty-eight (28).
WARNING:
Do not use a pump if it has been damaged. Use a mild solvent & clean cloth to keep the pump in
clean operating condition.
NEVER
carry hand pump by its Handle #10 unless it has been latched and secured or carry it by the Hydraulic
Pump Hose Assembly #17.
ALWAYS
replace damaged or missing parts.
WARNING:
Hydraulic pressure created inside the valve with a high pressure grease pump can stretch bolts on
bolted plug valve and cause leakage. Should this occur, release pressure in the pump and Hydraulic Pump Hose
Assembly #17. The flange should sit back down and leakage should stop.
WARNING:
Light valve lubricants, cleaners or liquid products can become a
dangerous
projectile in the event of
a hose or fitting failure while under high pressure.
DO NOT
remove nameplates or labels.
Personal Safety
Stay alert
. Do not use while tired or under the influence of alcohol, drugs or medications.
