GENERAL

The Fluid Kinetics Stabilizer/Separator, close-coupled to the pump suction flange, provides three basic functions necessary for smooth, low-maintenance operation.

Volume Effect - Acting as a mini-storage tank, the Stabilizer/Separator provides a full charge of liquid when the pump valves open. In systems with marginal available net positive suction head (NPSH), it prevents cavitations. Also, because of its location, it acoustically uncouples the pump from the line eliminating acceleration head consideration.

Dampening Effect - The gas charge provides a capacitance or spring effect to absorb pulsation created by the abrupt flow change as the valves open and close.

Separation Effect - Entrained gas or vapor is removed before it can enter the pump suction manifold where the sudden pressure changes can cause gas to break out of solution and create partial cavitation.

DESIGN

Flow enters and leaves the Stabilizer/Separator tangentially, forming a low-velocity vortex. This vortex and the increased path length created by the elevation difference between inlet and outlet stimulates the release of any entrained gas. The freed gas moves through the perforated center tube to the gas or air pocket maintained at the top of the unit.

The only maintenance required is the periodic replenishment of the gas charge. In some applications with gas-rich liquids, it is necessary to vent off the separated gas. Gas/liquid level can be visually observed through the sight glass. Since disassembly is not required, normal operating personnel can safely recharge the Stabilizer/Separator.

CONSTRUCTION

The Stabilizer/Separator is of welded steel construction. Standard models are rated 100 psig in accordance with ANSI B31.3 Code. Inlet and outlet connections are ANSI 150-lb raised face flanges sized to match the pump suction flange. ASME Code construction is available.

An all-brass water sight gauge with shutoff valves is furnished for visual observation of liquid/gas level. Heavy-duty sightglass is available for other fluids. Gas fill and drain connections are 3000-lb NPT couplings.

Any gas compatible with the fluid can be used as a charging medium. Air or nitrogen are commonly used.

In highly corrosive service, the stabilizer can be supplied with non-corrodible internals and epoxy coating of wetted steel surfaces.

APPLICATION

The Fluid Kinetics Stabilizer/Separator should be used in any system where:
There is an NPSH problem.
A gas-rich fluid is being handled.
There is other evidence of suction cavitations (i.e., excessive vibration or excessive pump maintenance.
Installation is simply accomplished by direct-connecting the Stabilizer/Separator to the pump suction flange. Any compatible gas may be used as a charging medium.
