Air Pressure Booster Systems
What design standards are met?
System receiver tanks have an ASME U stamp and CRN number. Boosters are designed with a minimum 4:1 safety factor.

How do I control discharge pressure?
The booster comes with a built-in pressure regulator to adjust the maximum discharge pressure. During operation the booster will provide a discharge pressure that is typically 2-10% lower than the maximum discharge pressure. It is important to note that if the flow rate varies the discharge pressure will also vary. To maintain a constant discharge pressure, MPS recommends a tank mounted system with an additional discharge pressure regulator.
What is the difference between operational discharge pressure and the maximum discharge pressure?
The operational discharge pressure is the discharge pressure the booster produces while providing the desired flow rate. This pressure is lower than the maximum discharge pressure. As the booster approaches its maximum discharge pressure, it begins to slow down and the flowrate decreases. At the maximum discharge pressure it stops cycling because all of the forces in the booster are balanced. When a booster fills a tank, it stops automatically when it reaches the maximum discharge pressure. It restarts automatically when the pressure in the tank drops.
How do I control flowrate?
The booster automatically adjusts its cycle rate to match the desired flowrate. No additional flow controls are required.
What is the operating life of an air booster system?
Air boosters are designed for 20 million cycles. The flowrate and supply pressure must be known to determine the life in hours. For example, with a supply pressure of 80 psi Model R03S will have an operating life of hours at a flowrate of 10 scfm and hours at a flowrate of 20 scfm. They can operate 24 hours a day, seven days a week.
What drive air quality is required?
Most boosters in an indoor factory environment operate problem-free on shop air with a +40• F pressure dewpoint and particulate filtration of 5• or better.
How much air is used to drive the booster?
Drive air consumption is approximately 1/2 to 1 times the amount of pressure-boosted air depending on the pressure boost ratio. For example, if 10 scfm of high pressure air is required, the Bootstrap Compressor will need 15-20 scfm of shop air, and 5-10 scfm of that air will be vented through an exhaust silencer.

Consult our engineering team with these determinants to select the right system.
Is there a way to tell when maintenance is required?
Maintenance is required when:
- The booster is leaking or not building pressure
- The booster is not cycling
Why do boosters fail?
The most common causes of booster failure are:
- Particulate contamination causing a jammed control valve
- Dynamic seals are worn out
MPS offers rebuild kits and rebuild services. Please call us to get a return authorization number and then we will analyze and quote the repair upon receipt. Quotes for all repairs are at no charge.
Is there a way to reduce downtime when a booster system needs maintenance?
Many customers keep a spare booster in stock. They depressurize the booster system, remove the worn out booster, and install the new booster.
Redundant booster systems are also available. A redundant booster system has a spare booster (or boosters) incorporated into the system. Valves are provided so that one booster can be completely isolated and safely removed from the system while the second booster is operating. This eliminates any downtime due to maintenance requirements.

Booster pumping in series questions | Page 2 - Eng-Tips
Pipeline booster pumps when the pumps are a long way apart can operate in both cases, e.g. you have a large hill in the middle, one pump generates enough head to get arrive at the base of the hill (but not enough to get over the hill) with a low pressure, enough to feed a larger head pump to generate enough head to get over the hill.
A different profile would mean that one pump at the start would be able to pump some liquid from one end to the other, but to get a higher flow you need a second pump half way along the line.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it. Actually flow control VFD shouldn't be used for pumps. That's for gas systems. How do you control flow in a liquid piping system. Open or close an inlet valve, or open or close an outlet valve. VFD flow control only works for pump systems when there are no valves in the system. How often is that. Pressure control VFD works for pumps with, or without valves. You know what NPSHR you have to maintain to keep the pumps running properly, so use pressure control to VFD to keep suction pressure >= NPSHR. Speed up pumps when suction pressure is greater than NPSHR, and slow down (to a stop) when NPSHA drops below NPSHR. Combine with a maximum pressure trip, for when pressures rise due to outlet valve closure. If you get too much flow at the discharge close down on the outlet valve and back the pump up on the curve anywhere, at least until it reaches the high pressure trip. You could do that by an outlet flow control valve, but why try to control the pump with that? The pressure control settings are already doing that for you.
No. Back pressure at the end of a pipe is often supplied by static head alone. You don't always need a valve. In the case of a pressure controlled vfd without a pipeline end valve, the pumps will run at full speed, or whatever lower speed becomes might become the limiting speed such that suction pressure remains above NPSHR.
If you absolutely must control FLOW from the end of the pipeline (be sure you really do have to control flow), you might be able to do that with a pump somewhere within the system (this applies to flow or pressure control of that pump), but only if the system hydraulic characteristics allow it. If the pump's downstream pipeline goes over a high hill, then down again to a lower elevation, you will probably have to use a valve at the end of the pipeline, or your pipeline might not run full in the downhill segment. In such circumstances high flow rates might have enough head loss that the pressure loss per unit length acts the same as an end valve (kind of a distributed backpressure) and the design flow rate can flow without a valve holding backpressure at the pipeline's end, although at other lower flow rates some back pressure might be required at the end of the pipeline to keep the pipeline flowing full at any lower flow rate. If you don't mind pipelines not flowing full, then you wouldn't need a valve at the end of the pipeline.
In chemical plant work flow control is often required. That is not true in liquid pipelines where the business objective of the pipeline is to move as much product as possible in the fastest time possible. You have to first realize that flow control is inherently contrary to the business objectives of liquid pipelines. It is actually the same for gas pipelines, but due to the compressibility of gas, there is wide pressure variation with flow which can vary constantly with temperature and line pack so customer requirements are usually based on meeting specific flow rates at specific minimum delivery pressures. It is rarely necessary that liquid pipelines actually have a specific required delivery flow rate from the end of a pipeline. Most liquid transportation contracts are based on moving a specific volume (10,000,000 bbls of your oil and maybe 20,000,000 of somebody elses) within a given month. We are usually not interested in doing that at anything but the fastest flow rate possible within a given system. For that example a design flow rate might be 1,000,000 bbls/day, but if we could do it at 1,100,000, we just might want to do it. That flexibility to flow at higher capacity should not be limited by somebody's arbitrary flow rate setting. It should only be limited by the maximum flow rate when the pumps start hitting NPSHR. That is a pressure setting, not flow rate.
