Pressure Booster Systems

 

Exact water pressure may be critical

R. L. Deppmann Company works with building owners, contractors, and engineers to provide pressure boosting solutions that meet your capacity, control, communication, space, and budget requirements.

We've categorized product choices below based on the specific need and complexity of the application. These categories - Point of Use, Good, Better, Best, and Premium - are not statements about the quality of the products, but rather designations intended to help you identify the right product for your specific application.


Point of Use Pressure Boosting Applications

When you need to get more flow or pressure for a specific application, point of use pressure boosters are ideal.

Does your Medical Office Building (MOB) Autoclave have enough pressure during some hours of the day, but not during others? Would your hospital cart washer work faster if it just had 15 PSIG more? Do the penthouse occupants in your building need more water in their deluge shower?

Features/Highlights

  • Inline pump requires no floor space
  • Variable or constant speed models
  • Lower installed cost than other systems
  • Immediate delivery
  • Good for retrofit
  • Fast installation
  • Simple controls

Capacity Ranges

Obviously, the capacity must match the need. We find many of
the commercial and health care needs are simple 5-50 GPM
systems with a quick 20-40 PSIG boost. In process systems,
the needs rise substantially.

"Good" Pressure Boosters

Bell & Gossett Model "Aquaboost" Pressure Booster Package

When your project requires a domestic water pressure booster with lower flow rates and just a little more pressure increase, the Variable Speed Aquaboost, Bell & Gossett and Goulds Water Technology, may be your package of choice.

Larger than a Point of Use pressure booster, this cost-effective system is perfect for smaller two- or three-story commercial structures, healthcare medical offices, and apartment buildings. This low profile packaged system uses B&G 3530 stainless steel pumps and a Xylem-designed controller for reasonably steady delivery pressure at an attractive price. Exclusive Multi-Master Control feature allows duplex units to continue operation if one pump or its control fails.

The system-mounted transducer will adjust the speed to provide a constant pressure as the load varies and the suction pressure changes. Reducing the speed will reduce the energy used and the electrical operating costs.

Features/Highlights

  • Two day availability on many packages
  • Simplex or duplex
  • Single point wiring connection with disconnect
  • Variable speed energy savings

Optional Accessories

  1. Low suction pressure cutout switch. We may supply this optional switch and ship it loose for installation and wiring by others.
  2. Bell & Gossett No Flow Shutdown Tank. We recommend this tank for steady pressure operation at low or no flow rate.
  3. Miljoco Suction Pressure Gauge PLF2598L-PBF-05
  4. Metraflex flexible pipe connectors (BBSC-1-1/2”, 2”, 3”). Duplex units match the pipe size of the booster system. Simplex units use 1-1/2” to 50 GPM, 2” to 90 GPM, and 3” above 90 GPM.

    "Premium" Pressure Boosters

    Bell & Gossett Model "TechnoForce XLS" Pressure Booster Package

    The B&G TechnoForce XLS has all the features and benefits of the "Best" Bell & Gossett TechnoForce e-MT Pressure Booster Package but includes two very different options. .

    Occasionally, the total flow is very large but the minimum flow is small and occurs often. This system allows the engineer to employ a small jockey pump along with larger flow pumps.

    The XLS is great for clients who have a system that cannot go down and a power generator is employed. It will allow the client to limit the KW used and avoid staging on pumps that would exceed the available power from the generator. Think hospitals and demanding clients.

    Now that you’ve identified whether you need Point of Use, or a Best, Better, or Good solution to fit your client’s needs, let's talk about the design and engineering of the system.

    Deppmann pressure booster design tools can help you determine the capacities you need for your specific system.

    Features/Highlights

    • Do you know what pressure your system requires? This R.L. Deppmann handy tool will guide you through the steps to determine the scheduled suction, discharge, and differential pressures which the B&G pressure Booster will need to provide.
    • The no flow shutdown tank is used to avoid cycling of the pressure booster, to maintain the minimum flow required for trouble free and long life of the operating pump, and to save energy. Do you know the capacities and B&G model number for the no flow shutdown tank you require? This tool will help you figure out exactly what you need. Coming Later in 2019.
    • Do you know how many pumps you should select to do the job? Do you know what the design flow rates are for those pumps? (Do you need 100%/100% or 50%/50% or something else?) This program helps guide you through the decision making process. Coming Later in 2019.

     


    ​Pressure Boosters "Parts & Service"

    R. L. Deppmann Service Techs have to expertise to troubleshoot and repair our most complex pressure boosters down to the simple point of use products.

    Have you had a Pressure Booster “Tune-up” in the last three years?

    Pressure Boosters, like many most other pieces of equipment, require periodic maintenance. We recommend a troubleshooting service visit to adjust the parameters to match current needs and well as a review of any service trips or error messages. We check the operation of the sensors, controls, pumps, motors, and valves. If your system is an older constant speed system we can clean and repair the PRV/check valves and even offer an analysis of energy savings to convert to variable speed.

    Frequently Asked Questions

    Does my system need maintenance?

    • There is a list of maintenance requirements which varies depending on the model you have. The pumps in general do not need much attention. The older constant speed pressure boosters do have pressure regulating valves that should be cleaned and reset every 3-4 years.

    Are parts available for my system?

    • Most parts are available for the pumps, valves, and sensors. Some of the electronic parts in older Technologic 1000, 2000, and 5500 series are no longer available due to upgrades in microprocessors. We can offer upgrades.

    How much money will I save if I upgrade to the newer variable speed technology instead of my constant speed unit?

    • The actual savings depends on the size of your system and the varying suction pressure from the city in your area. Our sales engineering department can do a free analysis and give you an idea. Here is an example of energy savings.

    Example of savings converting to variable speed.

    Assume you have a larger 10 story apartment building with (2) 20 HP 3500 RPM constant speed pumps on your Domestic water pressure booster. Assume you pay 14 cents per KWH and the system was designed on the 1980s normal minimum suction pressure default of 30 PSIG.  If the city pressure is normally 50 PSIG, how much can you save with a R. L. Deppmann variable speed conversion kit?

    • Before = $7,700.00 operating cost per year
    • After = $3,800.00 operating cost per year
    • SAVINGS EXAMPLE: $3,900.00 PER YEAR
