Operating manual
GEA Hilge HYGIA K
Product description
Hygienic design
Because of the consistent hygienic design and the use of
materials that are free of both pores and inclusions, the pump is
highly suitable for use in:
– pharmaceutical industry
– medical technology
– processes in bioengineering
Special areas of application can be found in the delivery of ultra-
pure water and water for injection as well as in systems for the
production of FDA-approved parenteral and infusion solutions.

Proper usage
3.3.1
Pumped liquids
Only pure or slightly contaminated liquids may be pumped. These
liquids may not chemically or physically attack the pump
materials or reduce their strength. If liquids with a viscosity
greater than that of water are to be pumped, make sure that the
motor will not be overloaded. The pump may not be operated
beyond the maximum permissible values. Even short periods of
pressure overload (e.g. as a result of a pressure surge) should be
avoided.
3.3.2
Minimum flow rate Q
min
Do not operate the pump below the minimum flow rate of
Q
min
= 10-15% Q

.
3.3.3
Connections and pipelines
The nominal diameters of the system pipelines should be equal to
or greater than the nominal diameters of the pump, i.e. DNE
(suction side) and DNA (pressure side), and the elements that are
to be connected to the pump must conform exactly to the design
standard/specification of the mating connector piece installed on
the pump. The suction line must be absolutely leakproof and if
possible laid out in such a way that no air pockets can form. Avoid
tight elbows and do not install valves immediately upstream of the
pump. On the suction side, provide a straight pipe section with a
minimum length of five times the pipe diameter. The suction head
of the system may not exceed the suction head guaranteed by
the pump.
3.3.4
Motor operation
Do not start and stop the motor more than 15 times per hour.
3.3.5
Design
All information and descriptions in this operating manual
concerning the use and operation of the pumps are based
exclusively on the standard designs.
These rules do not apply to special designs, customer-specific
modifications, or random external influences that may occur
during use and operation.

Technical data
3.4.1
Pump designation
The HILGE pump designation is structured as shown below:
3.4.2
Pump serial number
The pump can be identified by the pump serial number. When
ordering spare parts, always state the pump serial number.
WARNING!
Improper usage!
▲
Death, serious bodily injury, damage to prop-
erty.
►
Pump only liquids that are specified in the
order. The pump has been specially designed
for that purpose.
►
Operate the pump only in the electrical net-
work specified in the order.
WARNING!
Overloading the pump!
▲
Death, serious bodily injury, damage to prop-
erty.
►
Use the pump only under the indicated oper-
ating conditions.
►
Also avoid brief overpressure situations (e.g.
caused by pressure surges).
