How do you prime a Hale pump?
Start the priming pump by pulling the priming handle. In 10 to 30 seconds water will enter the main pump and the pressure will rise. Open the discharge valve slowly and lock in position. STREAM IS FLOWING THROUGH THE DISCHARGE HOSE.
When should I pump in RPM mode?
The rpm mode will allow the pumper to continue to operate if a pressure sensor clogs or fails and will allow constant engine speed operation for certain types of equipment like some types of CAFS or other engine driven equipment that need a relatively fixed speed for best performance.
What is PTO in fire tender?
Power Take Off For Fire Tenders.
What rpm do you draft at?
Throttle up to around 1,000 RPM make sure you are in volume mode and not pressure mode, open up your intake and pull your primer for 30-45 seconds and you should have a draft as long as everything is tight. 2. Another way is to obtain a draft is by using a low level strainer with a jet siphon.
What is the difference between RPM and pressure mode?
In pressure mode the governor maintains a constant pump discharge pressure. The discharge pressure is monitored and compared to the selected pressure setting, the engine RPM is varied to keep the discharge pressure at the selected setting. In RPM mode the governor maintains a constant engine RPM.
What is PTO gearbox?
A power take-off is a gearbox that directs power from the engine and transfers that power to auxiliary equipment through the rotation of the PTO gears and the vehicle transmission gears meshing. The power is generated from the truck’s engine power and is used to power the piece of equipment on the vehicle application.
Do you draft in pressure or volume?
The higher the pressure, the less volume one can draft.
Why do you relay pump in RPM mode?
For relay operations, using rpm mode eliminates the possibility of the governors on the supply engines getting out of sync, which can result in the supply engines chasing the pressure setpoint.
When should you switch from pressure to volume?
Volume Mode should be used when pumping more than one-half the rated capacity of a pump. It should be used during defensive operations (i.e. Master Streams) and when drafting. TRANSITIONING BETWEEN PRESSURE AND VOLUME MODES – Typically, the mode should be set at the start of pumping operations before throttling up.
How does PTO pump work?
Why does my pressure switch Keep clicking on and off?
Switch Clicks On and Off Repeatedly One of the most frequent culprits is a blown bladder in the water tank. You’ll need to replace this component, and also inspect the switch contacts to see if they’ve suffered any damage from the cycling.
Why is my water pump pulsing?
When wells pulsate, it’s usually because there’s not enough water pressure in the well’s water tank. Well water tanks have an internal air bladder, and an external electrical switch. When either or both of these components wear out, owners start noticing pulsing water going through their pipes.
How many gallons per minute does a Hale pump use?
Covering a range of capacities from 750 Gallons Per Minute (GPM) (2,838 Liters Per Minute, LPM) to 2,250 GPM (8,516 LPM), Hale pumps offer the versatility, dependability, reliability, and ease of operations necessary for effective fire fighting. This section reviews the principles of operation of Hale’s single-stage and two-stage midship pumps.
How do you use a Hale pump drain valve?
1-25 These valves can be used in either suction or discharge lines. Each discharge valve ona Hale pump may be equipped with a drain. Opening the drain before uncoupling the hose relieves the pressure in the line. Also, water must be drained from the pump during freezing conditions through the main drain valve.
What if I cannot correct a problem with my Hale pump?
If you cannot correct a problem, please have the following information ready prior to calling the Hale Customer Service Technician Department for assistance. Customer Service Number: 610-825-6300. q Pump Model and Serial Number
What kind of transmission does a Hale pump have?
The midship transmission is capable of handling full engine horsepower, enabling the pump to meet optimum performance levels as well as all torque requirements for over the road applications. LP and XP Gearbox In addition to the standard Hale gearboxes there is also available a “P” series gearbox.
