1.2 Notes
The symbols and notes below may appear in
Grundfos installation and operating instructions,
safety instructions and service instructions.
Observe these instructions for explosion-
proof products.
A blue or grey circle with a white graphical
symbol indicates that an action must be
taken.
A red or grey circle with a diagonal bar,
possibly with a black graphical symbol,
indicates that an action must not be taken

2. Product introduction
2.1 Product description
NB, NBG, MTB are non-self-priming, single stage,
centrifugal volute pumps with axial inlet port and
radial outlet port.
NB pumps comply with EN 733.
NBG pumps comply with ISO 2858.
2.1.1 Pumped liquids of NB, NBG
NB, NBG pumps are suitable for clean, thin, non-
explosive liquids without solid particles or fibres. The
pumped liquid must not attack the pump materials
chemically.
2.1.2 Pumped liquids of MTB
DANGER
Flammable material
Death or serious personal injury
‐The pump must not be used for the
pumping of inflammable liquids, such
as diesel fuel, petrol or similar liquids.
MTB pumps are suitable for industrial machine tool
applications, such as:
• machining centres
• cooling systems
• grinding machines
• lathes
• parts cleaning systems.
MTB pumps are designed specifically for the transfer
of liquids containing solid particles. The pumps are
capable of pumping liquids with particles up to 20 mm
in size and a weight percentage of up to 1.5 wt%.
When pumping abrasive particles, a reduced life of
pump parts can be expected.

2 Used for pumps where the pump shaft input power
exceeds 200 hp (150 kW) and is not regulated under
the DOE pump rule.
3 Special cases with power sizes above 200 hp (150
kW) which are still regulated under the DOE pump
rule. For example: Pump has a P2 value of 198 hp
(147.6 kW) in its duty point (in DOE scope) but
customer wants the 215 hp (160 kW) motor instead of
the 200 hp (150 kW). The pump is in scope of the
DOE regulation and requires a PEI value and a motor
code.

3. Receiving the product
3.1 Performance test
The pumps are tested 100 % before leaving the
factory. The test includes a function test where the
pump performance is measured to ensure that the
pump meets the requirements of relevant standards.
Test certificates are available from Grundfos
3.2 Transporting the product
WARNING
Overhead load
Death or serious personal injury
‐Pay attention to the pump weight, and
take precautions to prevent personal
injury if the pump topples or falls by
accident.
• Always transport the pump in the specified
position.
• Securely fasten the pump to prevent damage to
the shaft and shaft seal caused by excessive
vibrations and knocks.
• Do not lift the pump by the shaft.
3.3 Inspecting the product
• Confirm that the product received is in accordance
with the order.
• Confirm that the voltage, phase and frequency of
