AVOID CAVITATION DAMAGE
One or several of the conditions shown in the chart below may contribute to cavitation in a system resulting in
premature wear, system downtime and unnecessary operating costs.
CONDITION
SOLUTION
Inadequate Inlet Line Hose Size
Increase hose size to hose size 3/4”-5/8”.
Water Hammering Liquid
Acceleration/Deacceleration
Hose should be no longer than 50’.
Rigid Inlet Plumbing
Use flexible wire reinforced hose to absorb pulsation and pressure
spikes.
Excessive Elbows in Inlet Plumbing
Keep elbows to a minimum and less than 90°.
Excessive Liquid Temperature
Use Thermo Valve in bypass line.
Do not exceed pump temperature 104°F.
Substitute closed loop with baffled holding tank.
Adequately sized tank for frequent or high volume bypass.
Pressure feed high temperature liquids.
Air Leaks in Plumbing
Check all connections.
Use PTFE thread tape or pipe thread sealant.
Agitation in Supply Tank
Size tank according to pump output - Minimum 6-10 times system GPM.
Baffle tank to purge air from liquid and separate inlet form discharge.
Clogged Filters
Perform regular maintenance or use clean filters to monitor build up.
Use adequate mesh size for liquid and pump specifications.
