A discharge separator on a liquid ring vacuum pump serves to separate the liquid (usually water) and gas being discharged from the pump. This separation is crucial for several reasons, including preventing siphoning and ensuring proper pressure for draining the liquid.

Our vacuum pump separators/silencers are standard carbon steel constructed with the rigors of industrial systems in mind.

Providing Noise Reduction

In addition to the primary function of separation, our air/liquid separators can help attenuate unwanted inlet and discharge noise. Minimizing your industrial noise level is an effective way to create a worker-friendly environment.

VPSS Grade II series of air/liquid discharge separator/silencers are designed for atmospheric applications requiring suburban/ residential noise attenuation (30-35 dB).

Our design configuration incorporates a tangential-side transitioned inlet, top air outlet and low-side liquid drain to cenrifugally remove process and sealing liquid from airflow before discharging to atmosphere. This configuration enables our VPSS Grade II series to effectively remove 99% of free liquid.

This can be beneficial in a number of different situations, such as when the vacuum pump is located in an area where noise would be disruptive, or when the vacuum pump is being used in an environment where noise can be a problem.

Vacuum Pump Separator/Silencers Varieties

There are a variety of vacuum pump silencers on the market, and each has its own set of features and benefits.

One type of vacuum pump silencer is the vacuum pump separator. This device is designed to separate the vacuum pump from the rest of the system, which can help to reduce noise levels.

We can provide you with Vacuum Pump Separators or Silencers. Vacuum Pumps are primarily engineered and designed to handle gas, such as air. They will normally operate with an open discharge to the atmosphere. Many times water is used as the liquid compressant on vacuum pumps and the amount of water that is needed depends on the degree of vacuum that is required.

Separator-silencers are used to remove liquid from gas flow vacuum systems. This can be accomplished by using either liquid-sealed rotary positive blowers or liquid ring vacuum pumps. These separator/silencers may be necessary for the inlet (vacuum) and also the discharge of a vacuum pump system. When there are more stringent acoustical environment requirements you will need significant inlet silencing.

Vacuum pumps discharge both water and air into the atmosphere, there are two problems involved: separating the water, and silencing the noise of air flowing from the discharge. Vacuum Pump Systems, Inc. can supply you with the discharge separators/sliencers for your system’s needs.

Two Phases of Operation

When it comes to sizing and selecting the appropriate separator/silencer for a vacuum pump system, there are two phases of operation that must be considered:

1) Start-up: This is where the vacuum pump has begun to evacuate the system, which began at atmospheric pressure. During this phase, power requirements and system pressure drop are at their greatest. As the system is emptied, the inlet pressure falls, resulting in a system pressure drop and lower power demands. The overall flow (ACFM) is rather constant, but because of declining inlet pressure, the volume of the discharge will decrease until normal and general operating conditions become restored.

2) Normal operation: During typical operation, noise levels are at their highest.

Liquid ring vacuum pumps are closed-loop on the suction side and discharge to the atmosphere on the outlet side.

The separator/silencer size is determined by the ACFM inlet gas flow with the seal fluid load in GPM. A second pump (barometric leg) may be required to drain the separator sump due to the vacuum condition.
