Pulsation
dampers (Suction-side and Discharge-side
air vessels and Accumulators)
Suction-side and Discharge-side
air vessels as well as Accumulators are used in long
suction and discharge pipes to smooth the pulsation of the
flow. The also inhibit shock waves arising from mass accelerations
Strainers
prevent malfunctions in metering pumps and protect the
pump from damage.
Relief
valves
Plunger and membrane pumps are positive displacement pumps,
i.e. the delivered volume is independent of discharge pressure.
A relief valve prevents a rise in pressure in excess of desighn
values.
Pressure
sustaining valves
are fitted in the discharge pipe when the suction pressure
is higher than the discharge pressure..
Injection
points
are used for adding small quantities of liquids to large
flows.
Automation
Electric
stroke length adjustment
Stroke length adjustment with an electric motor is applicable
to nearly all application, and special components are available
for explosion-proof situations.
