Code example (EV range):
NVK 30 /13 A B C D E F G H J K L M N.
Where:
NVK = Pump model
30 = Rated flow [m³/h] (varies: 30-95).
/13 = No. of stages/impellers. (See model and stages below for more detail).
A = No. of trimmed impellers, if "Empty" = none.
B = Flange type: "F" - round.
C = Materials: "G" - (cast iron/Stainless steel); "N" - (AISI316/EN1.4401).
D = Motor power (kW x 10).
E = Motor type: “Vacuum” (pump without motor), "T" - 3-phase; "M" - 1-phase.
F = Frequency: "5" - 50Hz; "6" - 60Hz.
G = No. of motor poles: "Empty" - 2 poles; "4" - 4 poles.
H = Mechanical Seal: "B" (balanced).
J = Elastomeric and mechanical seal material: E1 (SiC-Carbon Graphite-EPDM) or E2 (SiC-SiC-EPDM).
K = “IE…” motor efficiency class IEC60034-30, where applicable, “Vacuum” (pump without motor).
L = “Vacuum” standard version,“M” (oversized motor).
M = "Vacuum” - standard version.
N = Motor voltage, “Vacuum” (pump without motor).
NKV 32: stage from 1 to 13 (50Hz) and from 1-1A to 8 (60Hz);
NKV 45: stage from 1-1A to 13-2A (50Hz) and from 1-1A to 7 (60Hz);
