3. CONFIGURATION AND FUNCTION
3.1 Description
M2500G modular progressive distributors have the following basic configuration (see also Fig. 1):
Fig. 1
Depending on the desired number of outlets and metering quantities, attach from 1 to 10 "functional twin segments" to the
inlet segment with the lubricant inlet opening (with selectable thread options). These each consist of a base segment (which
has 2 outlet openings) and a piston segment mounted above it. The metering quantity displaced into the piston segment is
normally fed through to the outlet openings of this associated base segment (outlets may not located alongside each other).
The end of the block is formed by the end segment, which is identical for all distributor variants.
The inlet segment, base segment and end segment are clamped together with 3 clamping rods. The clamping rods are round
rods with the same thread at each end. They are screwed into the inlet segment. During assembly the basic segment and end
segment, which contain through holes, are assembled to each other and self-locking nuts attached to the ends to secure
them. The functionally necessary connection holes between these segments are sealed (against leakage to the outside) by O-
rings in the contact faces (see Fig. 2).
Fig. 2
The base assembly group (see Figs. 2 and 3) can be regarded as an assembly unit in its own right. It remains a constant
element which generally remains unchanged even if changes in metering quantities are required.
Each selected piston segment is bolted to the base segment with 2 hexagon socket-head screws ("assembly screws"; see
Fig. 3). The connection holes between these two segments are also sealed with O-rings.

3. CONFIGURATION AND FUNCTION
Fig. 3
There is no connection between the individual piston segments (air gap). This is a great advantage of the M2500G, it means
that any piston segment can be exchanged without major assembly work (just undo the assembly screws then tighten them
again) if for instance the metering quantity of an existing distributor subsequently needs to be changed (see Fig. 4).
Fig. 4
3.2 Variation in the metering quantities / number of outlets
So as to be able to cater for a very wide range of applications and provide the greatest possible number of metering quantity
variants in conjunction with the specified number of outlets (to match the existing lubrication points), the M2500G has been
designed with the following design features:
Configurable number of segments
This means the "functional twin segments", see Fig. 5.
The number of these ranges from a minimum of 3 to a maximum of 10. Selection of the number depends on the desired number
of lubrication points in conjunction with the required metering quantities.

3. CONFIGURATION AND FUNCTION
Fig. 5
Piston dimensions
Piston segments with various different piston diameters (4, 5, 7 and 9 mm) and different axial strokes allow selection of the
required quantities of lubricant. These are used to generate the various different metering categories (see Table 1).
Piston segments in “S” and “T” versions
The piston segments are available either as S (= Single outlet) or as T (Twin outlet) versions. This is also shown in the legend
on the top face of the segment (see Fig. 6).
During a lubricating cycle (lubricating cycle: all the pistons of the distributor perform a back and forth movement in a
positively actuated cycle) a "T" piston segment delivers the same quantity of lubricant in the direction of each of the two
outlet openings. It has an internal grub screw which blocks the connection between the two outlets.
An "S" piston segment lacks this grub screw. It delivers the entire quantity (i.e. a double quantity) in the direction of only one
of the outlet openings. As a rule one of the outlet openings in the respective base segment is then blocked with a plug screw
(except in the case where an "alternative outlet opening", optionally right-hand or left-hand, is open. Then both the outlet
openings of the base segment must be blocked).
A listing of the available metering quantities for the various piston segments is shown in Table 1:

3. CONFIGURATION AND FUNCTION
Fig 6
Cross-port version
In order to achieve outputs of large amounts of lubricant, adjoining piston segments can optionally be connected by means of
cross-ports (lubricant bridging pieces, bolted on). These direct the lubricant towards the end segment.
Note that in this case the "normal" outlet openings (the outlet openings of the respective base segment used without a cross-
port fitted) must be closed off, because now the "alternative outlet opening" (see Fig. 1) is being used as the lubricant
transport opening.
Furthermore it should be noted that an "S" piston segment can accept a maximum of one bolted-on cross-port, a "T" piston
segment can accept a maximum of 2 bolted-on cross-ports. In addition, cross-ports cannot be chained together in sequence
(without a gap), otherwise a collision would occur.
In this connection see also Fig. 7. This shows the arrangement on alternate sides.
A theoretical extreme variant, which certainly would not be encountered in practice, is described below to provide the user
with an understanding of the arrangement of cross-ports:
Requirement: Within the range of available selections for the product code of an M2500G distributor as a standard
product, a variant with only a single outlet and the maximal available metering quantity for an M2500G
distributor is specified.
Solution: 1.) The distributor may have only "S" piston segments (even just 1 "T" segment would result in the number
of outlets being greater than 1).
2.) The distributor must be fitted with 10 functional twin segments, otherwise the maximum metering
quantity will not be achieved
3.) Selection of piston segments rated for the maximum metering quantity (1.31 cm3per lubricating cycle).
The distributor could then appear as follows (see Fig. 7):
“S“- segment
„T“- segment

3. CONFIGURATION AND FUNCTION

Bypass segment
The bypass segment (see Fig. 8) can be bolted on to the existing distributor in place of a piston segment.
Fig. 8
Its external dimensions are the same as those of a piston segment, but it does not contain a piston and has merely a
bridging function. When it is fitted as an exchange item, the open outlet holes on the respective base should be blocked
(see also Fig. 9).

3. CONFIGURATION AND FUNCTION
The practical use of this element arises when for instance the number of lubrication points in an existing system has to be
reduced but it is not desired to change the basic configuration of the distributor (the basic group remains the same / no
change to the attachment of the distributor).
The bypass segment is seldom required for a newly installed distributor, unless it is desired to configure it for the option of
subsequently adding further lubrication points (or metered quantities).
3.3 M2500G as a group lubrication distributor with solenoid valve
Fig. 10
In contrast to the normal version, the M2500G as a group lubrication distributor requires a special inlet segment which is
dimensionally larger (designated the "valve block" in the code), which can accept a solenoid valve (see "Dimensions").
The 3 solenoid valves are suitable both for grease and also for oil. The codes allow selection of the 24 V DC, 110 V and 230 V
AC versions. They are for use in group lubrication systems.
The following 2/2 solenoid valves are available:
1. 2/2-way solenoid valve, NC, PN350, 24 V DC / Art. no.: 38152M115
2. 2/2-way solenoid valve, NC, PN350, 115 V AC / Art. no.: 38152M116
3. 2/2-way solenoid valve, NC, PN350, 230 V AC / Art. no.: 38152M117
(respective cable connection box for each: Cable connection box DIN 43650 - AF3 - PG11 / Art. no.: 769282923)
3.4 Monitoring
Fig. 11
Special piston segments can be fitted with visual indicators or electrical switches for functional monitoring of the distributor
and for controlling the system. These can be selected by the appropriate item in the distributor code. The visual indication or
electrical switching operation is actuated by the movement of the piston (stop). Right-hand and left-hand versions are
available. If necessary, multiple indicators / switches can be fitted to a distributor at any desired piston segment positions.
Note that a switch or optical indicator that requires a movement pin can be fitted only to metering categories 20 (piston
diameter 7 mm) and above (see Table 1). The various monitoring elements are described in more detail below:

3.4.5 Monitoring with movement indicator
Fig. 16
This visual indicator is intended for the base version, where it performs the equivalent function to the monitoring switch.
Instead of the switch (see under "Monitoring switch") it contains a transparent protective cap. The pin is visible at each
lubricating action.
If necessary this version can easily be exchanged for the version with the monitoring switch.
3.4.6 Visual "colour-change" cycle indicator
Fig. 17
These visual indicators can be fitted to each piston segment (without pin) instead of the piston stop screw. They contain a
magnet which alternates as the piston moves. This causes a coloured liquid to be displaced, leading to an alternating
light/dark effect.

6. CODING
6.1 Explanation
The M2500G should be coded according to the summary from "A." to "H." (see pages 5 – 6).
Note especially here that:
For "D." (monitoring): for the distributor several monitoring variants are available for selection.
Since the number of coding characters is limited to 2, the largest number should be selected
here, e.g. the "09" for the selected monitoring switch "05" and limit switch "09".
For this special case, the code "X01" (according to "H. Accessories") should be appended and
the additional monitoring variant (here "05") described verbally (e.g.: Segment 3 with
monitoring switch 05).
For "E." (thread): The choice "C", "A" or "B" allows only one type of thread to be selected. This applies both to
the inlet and also to the outlet openings. A combination such as "UNF" for inlet, "G" for outlet
is not permitted. see also under 6. (Dimensions).
6.2 Coding the segments / outlets
The desired functional twin segments (base segment with its associated piston segment) are coded from the inlet segment
towards the end segment:

6. CODING
This establishes the link between metering quantity and the position / number of the outlets.
Each twin segment is described 1. by a code number and 2. by a code letter (e.g.: "3A").
The selection is made according to Table 4:
T : piston T segment; base segment with 2 outlets
SL : piston S segment; base segment with 1 left-hand outlet
SR : piston S segment; base segment with 1 right-hand outlet
TCL : piston T segment; with left-hand cross-port (= base segment: 1 right-hand outlet)
T2C : piston T segment; with right-hand and left-hand cross-ports (= base segment: 0 outlets)
TCR : piston T segment; with right-hand cross-port (= base segment: 1 left-hand outlet)
SCL : piston T segment; with left-hand cross-port (= base segment: 0 outlets)
SCR : piston T segment; with right-hand cross-port (= base segment: 0 outlets)

6. CODING
Here is an example of coding for a distributor with 3 functional twin segments:
Coding: M2503A01C004E4A8I00
Number of segments : 03 (3 segments)
Monitoring : 01 (with movement indicator / right-hand);
Thread : C (BSPP/G);
Valve block : 00 (without);
Segment / outlet coding : 1.) 4E = 20T segment with left-hand and right-hand cross-ports
2.) 4A = 20T segment (2 outlets)
3.) 8I = 40T segment + pin (2 outlets)
Accessories : 00 (without)
An inconvenient coding constellation should be shown in this position.
