3.3 Storage
3.3.1 Pump
To prevent water, dust, etc. from entering the pump, all openings
must be covered until pipes are connected. Apply a suitable
antirust agent on all machined, non-coated surfaces.
The antirust agent must meet these requirements:
• It must not attack rubber parts.
• It must be easy to remove.
• It must be applied according to the instructions of the
manufacturer.
If the pump must be stored for more than six months before start-
up, it must be protected against corrosion and damage:
1. Remove the stuffing box packing.
2. Spray the interior part of the pump case and the stuffing box
with a water-soluble type of antirust agent.
3. If the pump has not been connected to the pipework, cover the
pump suction and discharge flanges with full natural rubber
gasket material, and blank off these openings with metal
blanking flanges. Use at least four bolts for fastening.
4. Cover the opening of the stuffing box with a non-hygroscopic
tape. The stuffing box gland may be left on the pump shaft, but
must be wired or otherwise securely fastened in position.
5. Coat all exposed painted surfaces with an antirust agent that
can be readily removed with a petroleum distillate product.
6. Make sure that all exposed painted surfaces are dry, clean and
free of grease and other contaminates.
7. Cover the pump with a weather-resistant cover of waterproof
paper or plastic material to protect it against dirt and dust.
8. Inspect the pump at regular intervals during storage.
9. Rotate the shaft by hand every four to six weeks to prevent
pitting of the bearings.
3.3.2 Engine
Engines may be stored for up to 12 months in a dry room after
delivery. It is advisable to protect the engine with an air-
permeable cover. At least once a month, the engine should be
checked for accumulation of dirt or water. Any dirt or water must
be removed immediately.
If the engine is stored for more than 12 months or stopped for
more than six months, it must be protected against corrosion and
damage:
1. Drain the engine of oil, and replace the oil filter.
See service instructions.
2. Fill the engine housing with MIL-L-21260 oil.
See service instructions.
3. Replace the fuel filter. See service instructions.
4. Separate the engine from the pump by removing the coupling.
See service instructions.
5. Turn on the engine. See section 12.2 Manual operation.
Let it run for one or two minutes.
6. Drain oil and cooling liquid. See service instructions.
7. Drain fuel. To do so, loosen the drain screw in the tank bottom
(fig. 50, pos. A) and collect the diesel fuel in a suitable
container. After draining, tighten the drain screw in the tank
bottom.
Repeat these steps every six months.
4. Product description
4.1 Fire pump set
The fire pump set consists of a pump, a diesel engine with fuel
tank, and a controller. Pump and engine are connected via a drive
shaft or a flexible coupling. All components are adapted to each
other and mounted on a common base frame ready for
installation. The base frame is made of steel channel. The
controller and fuel tank can also be placed separately. This is
normally done in connection with JW6 and JX6 diesel engines.
The fire pump set comes ready for operation. The engine is filled
with cooling water, engine oil, etc. The batteries are filled with
acid and charged. The fuel system is vented, and the fuel tank
has a small quantity of diesel fuel. The correct engine speed has
been preset from factory.
As an example, the most important components of the fire pump
set are shown in figures 2 and 3. They show an HSEF pump set
with a Grundfos horizontal split case pump and a 4-cylinder
diesel engine, type JUH4, without turbocharger and charge air
cooler. Pump and engine are connected by a drive shaft. The
controller is mounted on the common base frame, and the fuel
tank is placed separately. The fuel tank is not shown.
Put a warning label on the engine:
Engine without oil. Do not start the engine.
