3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not take into account any unforeseen
circumstances and events which occur during installation, oper-
ation and maintenance. The operator is responsible for observing
the location-specic safety regulations, also with reference to the
personnel.
Risk of injury due to high pressure and escaping medium.
▶Before working on the device or system, switch o the pressure.
Exhaust or empty the lines.
Risk of injury due to electric shock.
▶Before working on the device or system, switch o the power
supply. Secure against reactivation.
▶Observe the applicable accident prevention and safety regula-
tions for electrical devices.
Risk of burns or re from hot device surfaces due to longer duty
cycles.
▶Only touch the device when wearing protective gloves.
▶Keep the device away from highly ammable substances and
media.
2 INTENDED USE
Micro diaphragm pump Type7604 solely serves as a micro dia-
phragm pump for the media permitted as per the data sheet.
▶Use the device only in conjunction with third-party devices and
components recommended and authorized by Bürkert.
▶Prerequisites for safe and trouble-free operation include correct
transportation, correct storage, installation, start-up, operation
and maintenance.
▶Observe the permissible data, operating conditions and condi-
tions of use of the respective devices or products. These spec-
ications can be found in the contract documents, operating

Risk of short-circuit
Escape of medium due to leaking ttings.
▶Make sure seals are properly seated.
▶Carefully screw together the micro diaphragm pump and manifold.
General hazardous situations.
Ensure the following to prevent injuries:
▶Observe the general rules of technology.
▶Do not use the device in an area prone to explosion.
▶Use the device only when it is in perfect condition and in accor-
dance with the operating instructions.
▶Secure the device or system to prevent unintentional activation.
▶After an interruption in the power supply, ensure that the pro-
cess is restarted in a controlled manner.
▶Do not modify the device. The micro pump cannot be dismantled.
▶Do not mechanically load the device.
▶Only trained technicians may perform installation and mainte-
nance work.
▶Install the device according to the regulations applicable in the
respective country.
▶Check the durability of the parts in contact with media before
using aggressive media.
NOTE!
Electrostatically sensitive components / assemblies!
The device contains electronic components that are susceptible
to the eects of electrostatic discharging (ESD). Components are
at risk if they come into contact with electrostatically charged
persons or objects. In the worst-case scenario, they will be
destroyed immediately or will fail after start-up.
▶Observe the requirements for minimizing or avoiding the pos-
sibility of damage caused by sudden electrostatic discharge in
accordance with EN61340-5-1.
▶Do not touch electronic components while the supply voltage is
switched on!

4 PRODUCT DESCRIPTION
Micro diaphragm pump Type7604 functions on the basis of the
function principle of a self-priming diaphragm pump. It is suitable
for the continuous conveyance of small quantities of aggressive,
inorganic and biological materials.
Integrated impulse generator
The micro diaphragm pump can optionally be equipped with an
integrated impulse generator. The impulse generator is integrated
into the cover of the device. The desired frequency can be set with
a rotary potentiometer.
4.1 Conformity
The device conforms to the EU directives as per the EU Declaration
of Conformity.
4.2 Standards
The applied standards as used to verify compliance with the Direc-
tives can be found in the EU type examination certicate and/or the
EU Declaration of Conformity.
5 TECHNICAL DATA
5.1 Operating conditions
NOTE!
Malfunction
▶Do not use Type 7604 outdoors without the appropriate hous-
ing and avoid heat sources that may cause the permissible
temperature range to be exceeded.
The conveyance rate of the micro diaphragm pump depends on:
• the viscosity of the medium being conveyed,
• the ow resistance values in front of and behind the pump
(e.g. piping, height dierence),
• the frequency of the supply voltage.
• the temperature
Ambient temperature +10 to +55°C
Medium temperature +10 to +60°C
Degree of protection IP40 (IP30 for rectangular plug Type2505)
Installation position arbitrary, preferably with ange facing
downwards.
