Installation & Operation Instructions: CIP Sanitary Flow Through Models

ATEX models must be grounded (earthed) before operation.

Turn pump off and remove all pressure from system prior to dampener installation.

Remove all pressure from dampener AND pumping system before disassembly, removal or maintenance.

Use compressed air or clean dry Nitrogen to charge dampener. DO NOT USE OXYGEN.

DO NOT exceed 150 psi (10.3 bar) maximum allowable working pressure (MAWP). Check maximum pressure rating

specified on dampener serial tag. If tag is missing, consult distributor or factory for specifications.

Always wear safety glasses and other appropriate safety equipment when installing, charging or repairing dampener.

Read and observe all safety warnings and instructions in this Manual before installation, operation or repair.

Before performing a system pressure test, dampener must be charged with 30% of system test pressure to avoid

possible damage to bladder.

Dampener must be cleaned and/or sanitized before use in a sanitary system.

Charge Notes

To be effective, dampener must be properly charged with compressed air or clean dry Nitrogen. DO NOT USE

OXYGEN. The gas used to charge the dampener may be required to meet standards established by 3A, EHEDG

and/or other agencies. The dampener cannot be charged until properly installed in the system.

The CIP dampener is available with two types of air controls for gas charging.

Adjustable Model

The adjustable model uses a self-relieving regulator and pressure gauge to set and control the gas charge in the

dampener. This model provides a means to easily adjust pressure to maximize dampener response but, a

compressed air line must be permanently attached to the dampener.

Chargeable Model

The chargeable model uses a Schrader type fill valve and pressure gauge to pre-charge the dampener. This type of

control is generally used when no source of compressed air is available near the dampener.

IMPORTANT! Do not charge dampener to more than 30% of pump discharge pressure. Overcharging

dampener may result in bladder failure. If dampener is overcharged compared to pump discharge

pressure, bladder will close and pump flow will be reduced or stopped. Symptoms of overcharging

include reduced flow, dampener vibration and/or pump shutdown.

Installation for Pump Discharge Pulsation

Installation Position

The CIP dampener is a flow-through design with 2 ½" tri-clamp connections on each end and should be installed in-line, as

close to the pump discharge as possible to absorb the pulse at its source and before any downstream equipment such as risers,

valves, elbows, meters, or filters. Dampener installation should be no more than ten pipe diameters from pump discharge. For

mechanical cleanability (clean-in-place or CIP), dampener can be installed in a downward angled position to assure complete

drainage. Vertical or horizontal installation is acceptable for in-line application (see FIGURE 1).

IMPORTANT! Dampener must be installed in the system with the arrow on the dampener body

pointing away from the pump and in the direction of fluid flow.

IMPORTANT! The tri-clamp style clamps used to install the dampener in the system must be installed

correctly and tightened completely, the clamps create product seal AND provide compressed gas

sealing so the dampener will hold the pressure charge.
