Technical data
Vertical high-pressure multistage centrifugal pump in in-line design
(F) = VdS certified pump version
With frequency converter
Nominal volume flow in m³/h
Number of impellers
Pump material code
1 = Pump housing stainless steel 1.4301 (AISI 304) + hydraulics 1.4307 (AISI 304)
2 = Pump housing stainless steel 1.4404 (AISI 316L) + hydraulics 1.4404 (AISI 316L)
5 = Pump housing cast Iron EN-GJL-250 (standard coating) + hydraulics 1.4307 (AISI 304)
Pipe connection
16 = oval flanges PN16
25 = round flanges PN25
30 = round flanges PN40
Seal type code
E = EPDM
V = FKM
K = Cartridge seal, versions without "K" are equipped with simple mechanical seal
S = Lantern orientation align with suction pipe
X = X-Care version
1 = Single-phase motor - None or 3 = Triphase motor
Motor electrical voltage (V)
50 - 60 = Motor frequency (Hz)
-38FF265 = Ø motor shaft – lantern size
Option code (if any)
16, 25 or 30 bars depend on the model
10 bars
Note : real inlet pressure (Pinlet)+ pressure at 0 flow delivered by the pump must
be below the maximum operating pressure of the pump. In case of exceeding
maximum operating pressure, the ball bearing and the mechanical seal could be
damaged or lifetime could decrease.
P Inlet + P at 0 flow ≤ Pmax pump
See pump rating plate to know the maximum operating pressure: Pmax
-30°C to +120°C
-15°C to +90°C (wiht FKM seal)
-20°C to + 120°C (with cast iron casing)
-15° to +40°C (other temperature on request)
Motor according to IEC 60034-30
