Suction Stabilizer
A suction pulsation dampener should always be utilized, as it will significantly extend the
pump’s operational life and efficiency. This system will typically be installed directly inside the
suction manifold, though external models are available. Pre-charge the pulsation dampener
in accordance
with the manufacturer’s instructions before beginning operations, and ensure
that no valves or turns are placed between the suction pulsation dampener and the suction
manifold inlet.
WARNING
The use of a high pressure source or nitrogen bottle to charge the
suction line pulsation dampener can result in catastrophic equipment
failure and serious injury to personnel.
For full operating instructions and guidelines for this equipment, see the documentation
provided by the pulsation dampener manufacturer.
Line Valves
Only full open valves should be used on the suction line to prevent any reduction or
interruption of flow and thereby ensure the efficient operation of the pump. Drain valves
should be installed at the lowest point in the piping, while vents should be located at the
highest point available. Do not under any circumstances use any valve that has the potential
to choke the flow of fluid through the line.
Suction Pressure Relief Valve
It is recommended that a suction pressure relief valve be used in the suction line to
prevent damage to either pump in the event of a high pressure surge occurring in the line. It
is recommended that the valve be located on the suction manifold of the pump, but may be
located elsewhere on the suction line at the customer’s discretion. The outlet line from the
relief valve should gradually slope down to the tank level, and should be supported to prevent
any dips or low spots where mud could collect, harden and potentially block flow.
The relief valve should be set to 50% greater than the normal operating pressure (70 psi
for normal operations, but this value may vary depending on the specifics of the job).
WARNING
The pressure relief valve outlet must not connect back to the pump
suction line. This can cause uncontrollable pressure surges, which
can result in equipment damage and significant injury to personnel.
