Safety
The manufacturer does not accept any liability for any damage caused by disregarding any sections of the entire documentation.
2.1 Intended use
• Only use the pump with suitable media (→ resistance lists).
• Do not use pump with solid particles or abrasive fluids.
If pumps are to be used for solid particles, then agree use
in advance with the manufacturer.
• Do not use pump with combustible or explosive fluids.
• Adhere to the operating limits and size-dependent minimum flow rates.
• Avoid dry running:
Initial dama ge, such as destruction of bearings, seals and
plastic parts, will occur within a few seconds.
– Make sure the pump is only operated with, and ne ver
without, pumped liquid.
• Avoid cavitation:
– Open suction-side fitting fully and do not use to regulate
flow.
– Do not open the pressure-side fitting beyond the
agreed operating point.
• Avoid overheating:
– Do not operate the pump whil e the pressure-side fitting
is closed.
–Noteminimumflow (→ Data sheet).
• Avoid damage to the motor:
– Do not open the pressure-side fitting beyond the
agreed operating point.
– Note the maximum permissible number of times the
motor can be swi tched on per hour (→ manufacturer's
specifications).
• Consult the manufacturer about any other use of the pump.
• If pumps are delivered without motors, then final assembly
as a pump assembly must take place in accordance with
the provisions of machinery directive 2006/42/EC.
Prevention of o bvious misu se (examples)
• Observe pump limits of use regarding temperature, pressure, flow and sp eed (→ Data shee t).
• The power consumption of the pump increases as the the
specific gravity of the pumped fluid increases. Adhere to
the permissible specific gravity in order to eliminate the
possibility t hat the pump, coupling and motor are overloaded (→ Data sheet).
A lower specific gravity is permissible. Adapt the auxiliary
systems accordingly.
• When conveying fluids containing solids, observe the limit
values for proportions of solid particles and particle size
(→ Data sheet, technical description).
• When using auxiliary plant systems:
– Ensure compatibility of the operating medium with the
product medium.
– Ensure constant supply of the relevant operating
medium.
• Pumps used with water as the pumped liquid must not be
used for foodstuffs or drinking water. Use with food or
drinking water must be specified in the data sheet.
• Typeofinstallationshouldonlybeselectedinaccordance
with these operating instructions. For example, the following are not allowed:
– Hanging base plate pumps in the pipe
– Overhead installation
– Installation in the immediate vicinity of extreme heat or
cold sources
– Installation too close to the wall
2.2 General safety instructions

Only one of the following shaft seals can be used.
3.4.1 Mechanical seals
Mechanical se als have a function-related leak.
• Single acting mechanical seal
• Single acting, non -balanced mechanical seal
• Double acting mechanical seal
• Double actin g, non-bal anced mechanical seal
3.4.2 Auxiliary systems Sealing systems
Only one of the following sealing systems can be used.
Quenching
When quenchin g, the pressure of the pumped mediu m is
greater than the pressure of the sealing medium. The seal
surfaces are lubricated by the pumped medium.
Blocking
When blocking, the pressure of the sealing medium is greater
than the pressure of the pumped medium. The seal surfaces
are lubricated by the sealing medium.
Examples of use:
• Pumped media which crystallizes or contains solids and
therefore damages the seal in the long-term
• Toxic conveyed media
• Environmentally hazardous conveyed medi a

4 Transport, Storage and Disposal
4.1 Transport
The user/owner is responsible for the transport of the
pump.
Weight specifications (→ documents for the particular
order)
4.1.1 Unpacking and inspection upon delivery
1. Unpack the pump/pump assembly upon delivery and
inspect it for transport damage.
2. Check completeness and accuracy of d eli very.
3. Ensure that the information on the t ype plate agrees with
the order/design data.
4. Report any transport damage to the manufacturer immediately.
5. Dispose of packaging material according to local regulations.
4.1.2 Inspecting pump and flange-mounted drive motor
1. Unscrew the motor fan cover.
2. Using a small screwdriver, rotate the motor fan in the n ormal direction of rotation.

Installation and connection
5 Installation and connection
For pumps in potentially explosive atmospheres (→ AT E X
additional manual).
NOTE
Material damage due to distortion o r passage of electrical
current in the bearing!
Do not make a ny structural modifications to the pump
assembly or pump casing.
Do not carry out any welding work on the pump assembly
or pump casing.
NOTE
Material damage caused by dirt!
Do not remove the transport seals until immediately before
settingupthepump.
Do not remove any covers or transport and sealing covers
until immediately before connecting the pipes to the pump.
5.1 Preparing the setup
5.1.1 Check operating conditions
Ensure the required operating conditions are met:
– Resistance of body and seal material to the medium
(→ resistance lists).
– Required ambient conditions
(→ 9.2.1 A mbient conditions, Page 34).
5.1.2 Preparing the installation site
Ensure the installation site meets the following conditions:
– Pump is freely accessible from all sides
–Sufficient space for the installation/removal of the pipes
and for maintenance and repair work, especially for the
removal and installation of the pump and the moto r
– Pump not exposed to external vibrations (damage to
bearings)
– N o corrosive exposure
– F rost protection
5.1.3 Prepare foundation and surface
Aids, tools, materials:
–Steelshims
– Spirit level
Installation options:
– With concrete foundation
– With steel foundation frames
– Without foundation
1. Ensure the foundation and surface meet the following con ditions:
– Level and horizontal
– Clean (no oil, dust o r other impurities)
– Capable of bearing the weight of the pump assembly
and all operating forces
– Stability of the pump ensured
– With concrete foundation: Normal concrete of strength
class X0 in accordance with DIN EN 206
2. Clean pump sump carefully.
5.2 Installing with foundation
NOTE
Material damage due to distortion of base plate.
Position the base plate as follows on the foundation and
attach.
5.2.1 Place pump unit on the foundation
Aids, tools, materials:
– Anchor bolts (→ installation drawing)
–Steelshims
– Mortar casting compound, no shrinkage
– Spirit level
1. Lifting the pump u nit (→ 4.1 Transport, Page 12).
2. Hook anchor bolts in the mounting holes o n the base plate
from below.
Observe manufacturers information when using the fixing
material.
14 SHB BA-2015.12.16 EN 300 486
Installation and connection
3. Position the pump u nit on the foundation. When doing so
lower the anchor bolts into the prepared anchori ng holes.
32 1 2
Fig. 6 Installation with foundation
4. Align the pump for height and system dimensions using
steel shims as follows:
– Arrange steel shims (2) to the left and right of each
anchor bolt (1).
– If the distance between the anchoring holes is
> 750 mm, then arrange additional steel shims (3) on
each side of the base plate in the center.
5. Ensure that the base plate lies flat against steel shims.
6. Check the permissible height deviatio n (1 mm/m) using a
mechanical spirit l eve l in a longitudinal and a transverse
direction
7. Repeat the proced ure until the base plate is correctly
aligned.
5.2.2 Attaching pump unit
Filling the base plate with mortar casting compound
improves dampening properties.
1. Fill the anchoring holes with mortar casting compound.
2. When the mortar casting compound has set, bolt the base
plate at three points to the specified tightening torque.
3. Before tightening the re maining bolts, arrange shims next
to every bolt to even out any irregularities in the mounting
surface.
5.3 Planning the pipes
Water hammers may damage the pump or the system.
Plan the pipes and fittings as far as possible to prevent
water hammers occurring.
Avoid misalignment between pipes.
Use fl exible rubber joi nts if necessary.
5.3.1 Specifying supports and flange connections
NOTE
Material damage due to excessive forces and torques on
the pump.
Ensure pipes are connected not under tension.
1. Support pipes in front of the pump.
2. Ensure the pipe supports have permanent low-friction
properties and do not seize up due to corrosion.
5.3.2 Specifying nominal widths
Keep the flow resistance in the pi pes as low as possible.
1. Ensure nominal suction pipe width is not smaller than the
nominal suction flange width.
– Recommended flow velocity < 1 m/s
–Maximumflow velocity = 9 m/s
2. Ensure the nominal pressure line width is not smaller than
the nominal discharge flange width.
– Recommended flow velocity < 3 m/s
–Maximumflow velocity = 12 m/s
