SUPPLY CONNECTIONS
11.1 HOSE CONNECTIONS
The tube connections are on the upper side of the pump. The standard threaded hose
couplings are DN4/6. Tube connections with hose nipples are available as an option (see
spare parts list chapter 16).
NOTE!
The hoses are to be assembled as follows:
Remove the union nut from the sealing ring couplings by turning it anti-clockwise. The nut
should be removed from the thread with great care so as to ensure that the loose sealing ring
in the nut is not lost.
Place the union nut over the connecting hose.
Place the sealing ring over the connecting hose with the thicker bead towards the nut.
Place the hose over the nipple on the thread.
The union nut is to be screwed tight by hand.
The hose will no longer be able to slip off, and is now compression-proof.
The hoses are to be removed in the reverse order.
Do not mix up hose-/tube connections for sample gas inlet and outlet;
the connections are marked accordingly! Check for tightness of all
sample lines after connection!
3-7.1-ME Gas sampling and gas conditioning technology
11
The tightness of the connections can only be guaranteed if the
connection hose has a straight rim (hose cutter).
NOTE!
Aggressive condensate is possible!
CARE!
Wear protective glasses and proper protective clothing!
11.2 ELECTRICAL CONNECTIONS
Connect the cables for the power supply as follows:
Power
Power
Figure 5 Connection of the distribution voltage

DANGER!
connected at a separate clamp.
The main circuit of the pump type SR25.1, SR25.1/EX and SR25.2-G must be equipped with a
fuse (0,25A recommended) corresponding to the nominal current (over current protection EN
60335-1);
An appliance to separate the motor from the power is to be provided in the electrical installation
(EN 60335-1);
The pump must be installed so that contact with alive parts (connections, possibly windings) is
impossible.
12
START-UP
Specific safety instructions for media being handled must be observed. Before pumping a medium, the
compatibility of the flexible tube material with the medium must be checked. The following steps
should be carried out before initial start-up:
The pump must not start against pressure or vacuum. When it is switched on the pressure in
the suction and pressure lines must be atmospheric. This must be so even when the pump
restarts after the power has been cut off for a short period.
The maximum permissible operating pressure (see technical data) must not be exceeded,
even when the flow is restricted.
Ambient conditions: see technical data.
13
CLOSING DOWN
The area in which the pump is situated when not in use must be kept
free of frost at all times!
NOTE!
If the pump is putting out of action be shure that the pressure in the lines is atmospheric. No
other measures need to be taken.

The springs may occur in different coulerings. This does not constitute a
quality defect. But make sure that the right spring strength is used. This
can be identified by the spring wire diameter. The „standard version for
NOTE!
Novoprene pump hoses“ (part no. 90P1010) has a diameter of 1,1mm and
the strengthened version for FPM-, Acidflex- or Masterflex-hoses“ (part
no. 90P1015) has a diameter of 1,2mm.
At first delivery two different types of springs are mounted in the driver
(right and left springs). When spare springs are ordered, for simplified
storage only one type will be delivered (right spring) that can be replaced
NOTE!
without any problems and guarantees full functionality when all four
springs are replaced.
Make sure that contact pulleys roll easily on the axis. After remounting the axis with contact
pulley into the driver the spring has to be mounted as shown in Figure 8. Please pay attention
to the alignment of the dent.
Remounting happens in reverse order.
While mounting pay attention to the fit of ‘rotational axisdriver’ and
check that the plunged boss at the shaft bore points to the front of the
pump head.
NOTE!
Use genuine spare parts only !
