Selecting a booster with ACE Online is divided into two main sections:

1. Pre-select: information cannot be edited or modified once the selection is complete and consists of three parts Entering general information, type of water supply and pressure and system configuration. Selecting the booster package. Selecting pumps for the package.

2. Post-select: information can be modified even after the selection is complete and consists of one part

Selecting the options for the booster package, control panel and drawdown tank.

Each part will be explained in further detail; as well, you will be taken through the various screens required to obtain a booster selection assuming that you are currently in the main booster selection screen (Figure 1).

Pre-select Part 1

To enter the general information NOTE: If you have calculated the total system flow or pumping head using the ACE Online tool beforehand, continue from step 3. 1. From the dropdown menu, select the Building Type. 2. In the Required System Capacity field, enter the total system flow (choose the appropriate unit from the

dropdown menu). 3. In the Required Pumping Head (THD) field, enter the total pump head (choose the appropriate unit from the

dropdown menu). 4. Select the number of pumps required for your booster package. 5. From the dropdown menu, select the appropriate package voltage.

To enter the type of supply and supply pressures NOTE: For water supply provided by a tank or cistern the project engineer must ensure that there will be a flooded suction as well as a net positive suction head (NPSH) to prevent cavitation and guarantee proper operation on site. For water supply provided by the city main do the following 1. Enter the minimum supply pressure (used to calculate the total booster pressure) in the Minimum Supply

Pressure field. 2. Enter the maximum supply pressure (used to calculate the pump shutoff pressure and determine the

construction of the package, for example 150# or 300# rating) in the Maximum Supply Pressure field.

To select the system configuration 1. Select the Operating Sequence (continuous or intermittent). 2. Select the Lead/Lag Booster Capacity Split (equal or unequal). 3. Select the System Speed Configuration (constant or variable). NOTE: The software adds 2psi to the boost pressure for variable speed packages to account for check valve losses and 5psi for constant speed packages to account for PRV losses. 4. To continue click System Search. A list of the most suitable booster packages will appear.

NOTE: Variable speed booster package only have equally split flow capacity. As well, Hotel or Healthcare Facility and Commercial building types only have the constant speed, unequally split flow system configuration.

Appendix A: Booster Design Basics

This information is intended to provide an overview of booster design basics and provides a better understanding of how to use the Booster Selection Module in ACE Online.

S. A. Armstrong provides both constant speed and variable speed booster packages. For the constant speed package you have the choice of equally or unequally split flows, however, for the variable speed you can only choose equally split flows. But how do you know what package to choose, how many pumps to use in your package or how to split the flow between the pumps? You will find the answer to this and other important questions regarding boosters here.

If you have any further questions that are outside of the scope of this appendix, refer to the Booster Design Handbook available at: www.armstrongpumps.com or contact the Technical Support Department at Armstrong.

To select a booster package you need to ensure you have the following

1. Total system flow (if not provided, you can calculate it by clicking Calculate Required Booster Flow? see Figures 1 and 2 and refer to the section on Calculating Total System Flow for more information).

2. Total pump head (if not provided, you can calculate it by clicking Calculate Required Boost Pressure? see Figures 1 and 3 and refer to the section on Calculating Total Pump Head for more information).

3. Minimum and maximum supply pressure (see Figure 1)

NOTE:

In ACE Online, the minimum supply pressure is used to calculate the overall system boost pressure. The maximum supply pressure is used to calculate the pumps maximum working pressure (MWP) using the maximum supply pressure and the pumps churn (or shut-off pressure) which plays a critical role in determining the pump construction and pressure rating (150# or 300#) of the booster package.

This information is based on Fire Test reports for the site and is usually provided by the project engineer. However, this may not always be the case in many preliminary designs, especially for budgetary pricing requests; when this information is not available, in Ontario the safety defaults used are

Minimum supply pressure = 30psi Maximum supply pressure = 80psi

Frequently Asked Questions

How many pumps should I include in this package (1, 2, 3, 4)?

This depends on your overall flow rate. A good rule of thumb is to consider a duplex (two pump) package for flow rates of 200gpm or higher and a triplex (three pump) package for flow rates of 300gpm or higher.

Will my system be running from a tank, cistern or using the city main?

If you are operating from a tank or cistern you need to ensure that the pumps you select have sufficient NPSH since the pumps provided by S. A. Armstrong require a flooded suction and net positive suction head (NPSH) to prevent cavitation and to run properly as well. As long as these requirements are met, running from a tank or cistern is no different than using the city main. In both cases you will need to enter the minimum and maximum supply pressure.

Will my system run continuously or will there be periods of low or no flow?

If your system will be required to run continuously, you will not need a drawdown tank. However, if there are periods of low flow or no-flow, you will have an intermittant system in which case you will require a drawdown tank. Drawdown tanks can be:

Remote mounted, therefore their construction is unaffected by the booster pressure. Skid or adjacent mounted, therefore the system pressure will affect the tank pressure rating. NOTE: A for sizing a drawdown tank is to use 20gal to 30gal of drawdown volume or 1/6 of the total flow.


11

Will I require a constant speed or variable speed booster package?

A variable speed booster package provides continuous pressure regulation without the need for pressure reducing valves. Examples of scenarios for which variable speed booster packages provide more significant cost savings are

Buildings with long runs of piping such as schools and hospitals. Buildings with undersized piping such as older apartment buildings. Buildings requiring motors sizes 10hp or larger (larger motors yield greater cost savings). Neighborhoods with varying supply pressures. Where the electric utility charges for daily or hourly peak power rather than cumulative power consumption. Solution to systems which have problems with water hammering or excessive maintenance of pressure reducing

valves.

A constant speed booster package is better suited to

Smaller systems with motor sizes less than 10hp (smaller motors do not yield as significant a cost savings). How should the flow be split through the pumps, equally or unequally?

Pumps used for variable speed booster packages only have equally split flows. However, pumps used for constant speed booster packages have both equally and unequally split flows; refer to Tables 1 and 2 below.

Table 1: Pump Capacity Splits for Duplex Booster Package

P-1 P-2 Why You would Choose this Split

33% 67% Very economical (especially for 200gpm and over). Effective use of pumping power. Ability to use 3-step sequencing control therefore optimizing BHP to flow.

50% 50% Economical for flow capacities below 200gpm. Equal ware between the pumps. Parts are interchangeable.

100% 100% Provides full standby incase of pump failure. Not effective use of BHP therefore suitable for packages with small motor sizes.

Table 2: Pump Capacity Splits for Triplex Booster Package

P-1 P-2 P-3 Why You would Choose this Split

20% 40% 40% Very economical (especially for 300gpm and over). Effective use of pumping power. Ability to use 5-step sequencing control therefore optimizing BHP to flow. P-1 acts as jockey for long periods of low-flow.

33% 33% 33% Suitable when minimum loads exceed 20%. Suitable for hospitals when there is no low-flow periods. Allows for 3-step sequencing
