3.3.2 Storage
3.3.3 Pump
Apply a suitable antirust agent on all machined, non-coated
surfaces. If the pump is to be stored for more than six months
before startup, treat the inner pump components with a suitable
antirust agent.
The antirust agent must meet these requirements:
• It must not attack rubber parts.
• It must be easy to remove.
• It must be applied in accordance with the manufacturer's
instructions.
In order to prevent water, dust, etc. from penetrating the pump,
cover all openings appropriately until the pipes are installed.
If this is not followed, it will be very expensive to dismantle the
pump to remove foreign bodies after commissioning.
Turn the pump shaft by hand once a month to prevent the shaft
seal from seizing up. To do this, disconnect the diesel engine
from the pump.
3.3.4 Engine
See the installation and operating instructions for the engine.
3.3.5 Coupling
See the installation and operating instructions for the coupling.
3.3.6 Controller
See the installation and operating instructions for the controller.
4. Product description
4.1 Pumped liquids
The pump is suitable for pumping clean and non-aggressive fire-
extinguishing water not containing additives or particles.
4.2 Applications
Grundfos HSEF pumps and Fire HSEF pump sets are designed
for firefighting applications for supplying water to hose reels, fire
hydrants or sprinkler systems. Do not use the pump sets for
ordinary pumping of liquids or pressure boosting.
The control cabinet must not be used to supply voltage to other
devices.
4.3 Pump set
The complete pump set consists of a pump, a diesel engine and a
controller. A flexible coupling connects engine and pump.
All components are adapted to each other and mounted on a
common base frame ready for installation. The base frame has
holes for fastening lifting equipment and holes for attaching it to
the floor. The pump set is delivered ready to use.
The fuel tank can be delivered separately in some options.
For installation and connection of fuel pipes, see section
6.9 Separate fuel tank.
The most important components of the pump set are shown in
figures 2 and 3.
Warning
When lifting the entire pump set, use the lifting eyes
specifically marked on the base frame. Never use the
lifting eyes of the individual components.
The lifting point should always be above the centre of
gravity of the pump set. See fig. 1. Alternatively, a
forklift suitable for the weight can be used.
Use certified and approved lifting equipment in
proper condition. See the weight specification on the
system nameplate located on the base frame near
the pump.
Only transport the pump set when the cabinet door is
closed and locked. Otherwise, there is a risk of
jamming.
Do not stand under or near the fire pump set during
lifting. When guidance needed for placing the pump
set; use wires - do not touch the pump set.
TM06 2425 4214
Store the pump set in a frost-free place in order to
avoid corrosion and damage.
Warning
Only use the pumps and pump sets for the
applications mentioned. Any other use is considered
improper. Grundfos cannot be held responsible for
damage caused by improper use. The risk is carried
solely by the operator.
