Deaeration Valve Assembly
ProMinent’s de-aeration valve assembly helps evacuate gases from pumps, preventing system backpressure and maintaining optimal pump operation. It allows accumulated gases to exit via the bleed valve, ensuring a consistent flow of liquid back to the supply tank. The valve’s design minimizes resistance to flow until it fills with liquid, directing most of the liquid through the main discharge line to maintain pump efficiency.
Product description
Deaeration Valve Assembly
Installation:
1. General
Install the pump in accordance with the instructions contained in the pump operating manual. The de-aeration valve assembly must be installed directly on the outlet side of the discharge check valve.
2. Routing of Bypass Line
The bypass line should be routed back to the top of the chemical storage tank. Install the pump so the bypass line is not submerged in the chemical. It is not recommended to pipe into the calibration columns because they will overflow after a short period.
Warning: install the bypass line so any bypassed air/gas is not rerouted into the suction line.
3. Calibration
In calibrating the pump, use a graduated cylinder as the fluid source. You must collect any fluid returned through the bypass during the calibration and subtract it from the quantity drawn into the suction line.
Maintenance
- Ensure the pump connections are correct and tight
- Maintain a clean liquid end with no buildup of chemical crystalline material. Especially check the bleed valve and discharge ball checks.
Replacing the bleeder valve O-ring:
- Unscrew the bleeder valve and carefully remove the O-ring with a small screwdriver
- Fit a new O-ring into the valve port and screw in the bleeder valve and tighten to 2.2-2.6 ft. Ib. torque

Overview
Help evacuate accumulated gasses – De-aeration Valve
Overview:
Some chemicals "off-gas" (i.e. decompose) when the pump is sitting idle; the gas accumulates and may cause the pump to lose prime. ProMinent's de-aeration valve assembly can help evacuate gases accumulated in the liquid end of the pump automatically even against system backpressure.
The de-aeration valve assembly operates by allowing any accumulated gases to exit, through the bleed valve. A small amount of liquid along with the expelled gases are channeled through the bleed valve and bypassed back to the supply tank. When gas is present in the de-aeration valve the resistance to flow through the bleed valve is relatively low. When the de-aeration valve becomes full of liquid the resistance to flow through the de-aeration valve increases dramatically, forcing most of the liquid to pass through the main discharge line.
