Description

Pressure booster pumps increase water pressure from city mains or private water systems. Applications include providing high water pressure for washing buildings, dairy walls or floors, hog parlors, poultry houses, rinsing or spray cooling equipment, lawn sprinkling and insecticide spraying.

Single-phase models are equipped with a capacitor start, thermal protected motor. Three-phase models require separate overload protection.

‡ Equipped with carrying handle. 132079 handle available as an option for other models. † Example: If PB0508A031 pump is connected to supply line of sufficient capacity, carrying water at 40 PSI, and the output of the pump is held to 7.3 GPM by a gate

valve, the pump will add 40 PSI to line pressure for a total output pressure of 80 PSI.

* Operation of pump in this range may result in reduced pump life and/or motor damage.

To keep pump and seal lubricated, a minimum flow of 1.5 GPM must always be maintained through the pump.

Pre-Installation

HANDLING

1. Use handle supplied to lift pump.

2. Avoid impact on pump or motor. In particular, avoid impact on discharge end of pump or rear motor access cover.

LOCATION

age and/or personal injury might result from an inoperative or leaking pump due to power outages, discharge line blockage, or any other reason, a backup system(s) should be used.

1. Locate pump as close to the fluid source as possible, keeping the inlet pipe short as possible.

2. Place unit where the pump and piping are protected from the weather and extremes of heat, humidity and below freezing temperatures.

3. Mount unit in a dry location that is easily accessible for inspection and maintenance. If a dry location is not available, mount it on a foundation well above the wet floor.

1. Make workshop child proof - use padlocks, master switches; remove starter keys.

2. Wear safety glasses when working with pumps.

3. Wear a face shield and proper apparel when pumping hazardous chemicals.

4. Keep work area clean, uncluttered and properly lighted; replace all unused tools and equipment.

no smaller than the corresponding ports of the pump (See Figure 1). Smaller pipe will reduce the capacity of the pump. Increase pipe size on long runs.

3. Avoid air pockets in inlet piping or air will accumulate at high points, making priming difficult.

4. Use pipe compound on all joints and connections. Use Teflon tape or plastic joint stik, on plastic pipe. Draw all pipe up tightly.

IMPORTANT: The entire system must be air and water tight for efficient/proper operation.

5. Provide guarding around moving parts.

6. Keep visitors at a safe distance from the work area.

7. Periodically inspect pump and system components.

8. Protect electrical cord. Replace or repair damaged or worn cords immediately.

PUMP INSTALLATION IMPORTANT: Pump is built to handle

clear water only; it is not designed to handle water containing sand, silt or other abrasives.

installed. Failure to do so may cause piping to break, pump to fail, motor bearing failures, etc.

2. If the pump is used as part of a permanent installation, bolt to a rigid foundation.

Use only components that are rated for maximum pressure pump can produce when used in boosting system or any other system. Do not exceed the total maximum pressure boost as listed per model in Performance Charts B.

PRESSURE BOOST SYSTEMS

1. On pressure boost systems, locate

the pump so that there will always be a positive supply of water to the pump (See Figures 6, 7 and 8).

2. For service convenience, install a

gate valve and union in the inlet and discharge line.

Do not use a globe valve or other restricting type of valve that will seriously restrict the pumps discharge capacity.

3. Install a check valve as shown in

Figure 6. Be sure check valve flow arrows point in the direction of water flow.

4. Whenever dirt, sand or debris is

present in the supply water, install a strainer or filter on the inlet side of

the pump (See Figure 7). NOTE: For heavy amounts of sediment, install a trap filter on the inlet side of the pump (See Figure 5). NOTE: Pressure gauges installed before and after the filter will show pressure differential indicating the need for filter replacement or cleaning.

If Air Pockets Form, Water Won’t Flow
