|INTRODUCTION: |ESTIMATED TIME: |

| |

|A portable pump is a valuable piece of equipment for every fire department to have. Portable pumps are defined as a “self contained’ pump, which can |

|be carried by one or two firefighters. Portable pumps are not only a value for rural firefighting but can be a great asset in an urban setting and |

|situations. |

|TYPES OF PUMPS | |

| | |

|Posititve Displacement pumps | |

|Do not require priming devices | |

|Pumps are lighter and simpler to operate | |

|Moving parts inside the pump are close fitting which leads to wear and damage if pumping “dirty’ | |

|water | |

| | |

|Centrifugal pumps |Most dept’s have centrigugal portable pumps. |

|Require separate primers | |

|Pumps may be heavier to move |Discuss the specific style of pump your dept |

|Pumps are not as prone to damage and wear |carries |

|Pump packing will need to be maintained | |

| | |

|Capacities and pressure |Discus specific flow rates (l/min) for the |

|Small volume – higher pressures |portable pumps in-sevice at your dept |

|Medium volume – mid –pressure | |

|Large volume – lower pressure | |

| | |

|Engine types | |

|Two-Cycle: There are advantages and dis-advantages to operating with a two-cycle pump. |Discuss and ensure ff’s know which style of |

|Advantages: light-weight, can operate on severe angles due the gas and oil being mixed together |engine your dept uses. |

|Disadvantages: fuel must be correctly pre-mixed with oil, two-cylce engines tend to run “rougher” | |

|than four-cycle engines |If it is necessary to pre-mix the fuel for a |

| |two-stroke engine discuss the mix ratio and |

|Four-Cycle : there are also advantages and dis-advantages to operating a four cycle pump. |type of oil to be used as per pump |

|Advantages: regular gas can be used (no premixing), smoother operation and better motor lubrication |manufacturer. |

|Disadvantages: heavier than two-cycle engines, engine must be on level ground so oil will be picked | |

|up for engine lubrication |Important: make sure ff’s are aware that |

| |four-cycle pumps need to be on fairly level |

| |ground during operation |

| | |

| | |

|MAIN FEATURES | |

| | |

|Starting devices: There are 4 types of starting devices used on portable pumps which include; | |

|Pull start: this is the simpliest type. A cord is wrapped around the flywheel and pulled to start the| |

|engine. Spare cords should be available in case of breakage | |

|Recoil start: cord is attached to the flywheel and automatically rewinds. | |

|Impulse start: with this type a spring is wound with a handle, a button is released and the spring |Discuss starting method of in-service pumps and|

|turns the engine. |any maintenance or trouble shooting that can be|

|Electric start: usually very reliable but does require a properly charged and maintained battery in |performed |

|order to operate. Battery adds weight to the unit. Many electric start units will have a back-up | |

|method of starting (pull start) in case of battery failure | |

| | |

|On / off devices | |

|May simply be an on / off switch or a older device that “grounds out” the spark plug causing the | |

|engine to stop. Regardless of the style devices should be; | |

|Dependable | |

|Located as to not allow the operator to come in contact with hot exhaust or present an opportunity | |

|for electrical shock to the operator | |

|Not cause damage by flooding or stalling the engine | |

| |Ensure stopping procedures are discussed for |

|Fuel tanks |specific pumps |

|Portable pumps may be equipped with fuel tanks attached directly to the engine or may come as a | |

|separate fuel tank feeding the engine with a fuel line (similar to an outboard boat motor) | |

| | |

|Things to consider: | |

|Beware of re-fuelling a tank attached to a engine that is hot. Fuel or fumes may ignite if they come | |

|in contact with a hot motor | |

|If a separate fuel tank is used ensure the fuel line is correctly hooked to the motor from the gas | |

|can | |

|Ensure vents are opened to allow for the proper flow of fuel and to prevent vacuum locks | |

| | |

|Choke: used for cold starts | |

| | |

|Inlets / outlets | |

|Most portable pumps have 65mm inlets and outlets however larger capacity pumps will have both 100mm | |

|inlets and outlets to allow for a greater volume of water. | |

| | |

| | |

| | |

| | |

|Priming devices | |

|Typically there are two types of priming devices; exhaust primer or hand primer | |

|Exhaust primer: most typical priming device. The exhaust system must be in good working order for the| |

|primer to function properly. Operator must be careful not to contact hot exhaust parts when prming | |

|Hand primer: works by pouring water directly into the casing of the pump through an intake pipe to | |

|create a prime | |

| | |

|Pet cock | |

|Drain valve to allow the pump tobe drained of watwer to prevent freezing and or to perform | |

|maintenance. Pet cock must be closed before starting and attempting to prinme the pump. | |

| | |

|Portable pump accessories | |

| | |

|Common accessories that should be available when using a portable pump should include: | |

| | |

|65mm to 65mm wye – pumps equipped with a single 65mm discharge can achieve greater volumes if | |

|siameses lines are used from the portable pump to feed directly into the 65mm intakes of the pumper. | |

|It is possible to exceed the rated capacity of the portable pump | |

|65mm to 38mm gated wye: if the protable pump is used to supply hand lines directly. Two 38mm lines | |

|can be used from one 65mm discharge | |

|Floating dock or strainer: docks and strainers keep the suction end of the line away from the bottom | |

|of the water source and prevents large objects and debris from entering the pump. Low level strainers| |

|allow water to be drawn from very shallow sources | |

|Hose keys / wrenches: fittings on the suction side of the portable must be tight in order to create | |

|air tight seal to maintain a draft | |

| | |

|PORTABLE PUMP OPERATION | |

| | |

|Start-up procedures | |

|Ensure pump is on a fairly level surface (if using a four stroke engine) | |

|Attach a dock or strainer to one end of hard suction | |

|Attach other end of hard suction to pump intake | |

|Attach line to hard suction – this is optional and may be used in areas of faster moving or deep | |

|water | |

|Open gas air valve if applicable) | |

|Open drain on primer (ensure pet cock drain is closed) | |

|Set choke | |

|Turn start button on (if equipped) | |

|Start the engine | |

| | |

|Priming | |

|Open pet cock on exhaust valve | |

|Activate exhaust re-direct lever | |

|Allow water to flow through exhaust pet cock | |

|Release exhaust lever | |

|Shut off exhaust pet cock | |

|Open discharge valve if equipped | |

| | |

|Precautions | |

|Be aware that pumps can and will vibrate. Pump may “dig in” to the ground | |

|Exhaust systems are extremely hot | |

|Listen for sounds of engine racing usually associated with the loss of prime | |

|Hot engines and exhaust nay create spot fires around a pump | |

|Always notify crews if shutting down the pump due to a loss of water, loss of prime or to re-fuel | |

| | |

| | |

| | |

|Refer to information sheets included in this lesson plan to highlight important information and to | |

|review parts of the portable pump | |

| | |

| | |

| | |

| | |

| | |

| | |

| |Make sure that the ff’s are allowing enough |

| |water to pass through the exhaust pet cock |

| |during priming operations to ensure and |

| |adequate pump prime. BE PATIENT! |
