3.4.1 Model code
The filter unit/filter housing is defined by the following model
code:
Basic Type
Pump version
Filter Size
OLFP - 1 / 2 - G - M - M - TM - N - E /-000
Measurement technology
Power supply
Clogging indicator
M = 230 V / 50 Hz / single phase / 0.37 kW
N = 400 V / 50 Hz / three phase / 0.37 kW
AB = 690 V / 50 Hz / three phase / 0.37 kW
N60, M60 = operation at 60 Hz
Z = without motor (for pump models O and Z)
Other voltages on demand
OLFP = OffLine Filter Presure
OLFPCM = OffLine Filter Presure mit ConditionMonitoring
1 = Size 1 (1x filter element*)
3 = Size 3 (1x filter element*)
6 = Size 6 (2x filter elements*)
O = with orifice, for flow, see figure:
volumetric flow through the orifice
G = with gear pump (only for sizes 3+6)
Z = without
M = MCS 14xx MetallicContamination Sensor
A = AS 1000 AquaSensor
Z = without
E = Standard, clogging indicator
B = Differential pressure gauge, optical (VM2BM.x)
C = Differential pressure gauge, electrical (VM2C.x)
D3 = Differential pressure gauge, optical/electrical (VM2D.x)
D38 = Differential pressure gauge, electrical VL x GW.0 /-V-113
Z = without
Nominal flow rate/type of orifice
2 = 2 l/min (Orifice A)
3 = 3 l/min (Orifice B)
6 = 6 l/min (Orifice C)
Z = variable (without orifice, without pump)
Filter element
TM = Trimicron
Sealing material
N = NBR
F = FKM (FPM, Viton®)
