Why Suction Stabilizers?

• Pulsation Problems Start on the Suction Side!

• Appendage and Flow-Through Available

• Minimize pump cavitation

• Increase useful life of fluid-end parts

• Reduce cost of system ownership

Cavitation can cause 10X the standard pulsations normally produced = less pump life!

Operators look for discharge dampener failure, but unstable suction is typically the root cause

Suction Stabilizer

Why Suction Stabilizers?

Definitions

Ha = (LVNC)/gxk

= Acceleration head

= Actual length of suction line= Average liquid velocity in suction line

= Speed of pump crankshaft= Constant depending on pump type= Gravitational constant= Constant depending on fluid compressibility

Acceleration Head Loss Formula

Flow-Through suction stabilizers isolate the pump from the remainder of the suction line = dramatic reduction of “L” line impact and overall less Acceleration Head Loss

Why Suction Stabilizers?

= Atmospheric Pressure

= Vertical distance from liquid surface to the pump centerline

= Friction losses in suction piping

= Acceleration head at pump suction= Absolute vapor pressure of liquid at pumping

Definitions

NPSHa = Pt + Hz – Hf – Ha + Pvp

NPSH improved through reduction of Acceleration Head Loss

Suction Stabilizer Performance

Common Stabilizer Solutions

• Simple Gas Cap Tanks – Gas pocket above fluid column

• Gas Charged – Stabilizer with gas cartridge requiring maintenance or replacement upon failure.

• Maintenance-Free Flow-Through – Virtually no maintenance required. • Suction Cellular Stabilizer

• Reactive Stabilizer

Suction Stabilizers – Gas Cap

Gas Cap or “Stand Pipe” or “Air Tank” designs are seldom maintained

Gas cap rapidly absorbed by fluid = Elimination of effect and cavitation introduced

Suction Stabilizers – Gas Charged

Gas-Charged units separate the gas from the fluid via a cartridge, bladder, or cellular membrane = No gas absorption; More stable performance; Improved pump efficiency

Requires cartridge charging and replacement

Maintenance Free

Cellular Suction Stabilizer

Virtually no maintenance required = low life $ cost

Flow-Through Reduces Cavitation

Cellular Suction Stabilizer

Maintenance Free

Flow Through Suction Reactive Stabilizer

• Virtually eliminates Acceleration Head/Pressure Loss

• Applicable to harsher fluids and higher temperatures

• Promotes acoustic isolation

• Consistent performance over a broad range of pressures

Maintenance Free

Flow Through Suction Reactive Stabilizer

Maintenance Free

Maintenance Free Vertical Tank Suction Reactive

Things to Remember

• Suction Stabilizers - Critical to your fluid delivery and ultimate discharge performance

• Discharge Dampeners – Reduction of acceleration and flow-induced pulsations

• Maintenance Free Options – Initially more expensive, but long-term costs lower
