9.5 Pumped liquids
The pump is suitable for pumping clean and non-aggressive fire-
extinguishing water not containing additives or particles.
9.6 Pump speed
The pump speed is stated on the nameplate. It is also stated on
the Certificate of Approval issued by VdS for pumps with VdS
approval.
9.7 Direction of rotation
The direction of rotation of the pump is clockwise when seen from
the drive end. The correct direction of rotation is indicated by an
arrow on the pump housing.
9.8 Liquid and ambient temperature
Liquid temperature
The pump is designed for liquid temperatures up to 120 °C.
Ambient temperature
The maximum permissible ambient temperature depends on the
driver and controller. See installation and operating instructions
for the driver and controller.
9.9 Relative air humidity
The relative air humidity must not be too high to prevent
condensation of moisture in the air. This may damage the
controller or the driver. If humidity is a problem, install a space
heater with a hydrostat.
9.10 Effect of ambient temperature and altitude on
engine/motor output
10. Installation
This section describes the installation of a complete pump set.
10.1 Location
Place the pump set in a dry, frost-free and well-ventilated
location. The pump set, primarily the control cabinet, must not be
exposed to direct sunlight.
Allow sufficient clearance around pump and engine to enable
inspection, repair and assembly work.
10.2 Foundation
We recommend to install the pump set on a concrete foundation
heavy enough to provide permanent and rigid support for the
entire system. The foundation must be capable of absorbing any
vibration, normal strain or shock.
As a rule of thumb, the weight of the concrete foundation should
be 1.5 times the weight of the pump set. The concrete foundation
must have an absolutely level and even surface. Insert anchor
bolts for securing the pump set. See fig. 10.
Make sure that the foundation is at least 100 mm (dimension x)
longer and wider than the base frame.

Note
Pump set with water-cooled diesel engine:
The maximum liquid temperature depends on the
coolant temperature required to cool the diesel
engine. See installation and operating
instructions for the diesel engine.
Note
See installation and operating instructions for
the driver.
Caution
The installation should be carried out by a
qualified person in accordance with the following
instructions.
Note
Observe also the instructions in the standards
applying to this product.
Warning
Pump set with diesel engine:
Ensure an adequate supply of air for engine
combustion and an adequate removal of heat and
exhaust gases.
Non-compliance or impairment of the ventilation
or exhaust gas system may result in suffocation.
Lubricants, fuels or other highly volatile or
combustible materials must not be stored near
the diesel engine. Such materials must be stored
in a suitable, separate room.
Note
The instructions in this section are
recommendations. The plant and machinery
installer is responsible for making a correct
foundation.
