1HM, 3HM, 5HM, 10HM, 15HM & 22HM.
1VM, 3VM, 5VM & 10VM.
Model nomenclature:
W XXX YY Z EM
Where:
W - flow rate (m3/h), either 1, 3, 5, 10, 15, or 22.
XXX - Model type: Horizontal (HM) or Vertical (VM) mode, where last (optional) digit can denote the variable speed drive as follows:
Null = standard asynchronous motor,
H = equipped with Hydrovar,
X = other drives,
E = e-SM.
YY - Number of impellers/stages
HM models: 2-25 stages only (02-25),
VM models: 2-8 stages only (02-08).
Z - Material, where:
(P) is plastic impeller and SS AISI 304 body (HM & VM models),
(S) is SS AISI 304 impeller and body (HM models only),
(N) is SS AISI 316 impeller and body (HM models only).
E = 5 - 6 digits for electrical specification.
M = 3 digits, where:
1st digit: Mech. rotary seal - V = Aluminium oxide (Ceramic),
or Mech. rotary seal - Q = Silicon carbide (Ceramic).
2nd digit: Mech. stationary seal - B = Carbon resin impregnated.
3rd digit: Mech. seal elastomers - E = EPDM.
Example code:
1HM03P05M5HVBE.
Max Working Pressure for VM models → 10 bar.
Max Working Pressure for HM models with stainless steel impellers and QBE Mechanical Seal → 16 bar (Depending on number of stages - see below),
Max Working Pressure for HM models with plastic impellers and/or VBE Mechanical Seal → 10 bar (Depending on number of stages - see below).
1HM (P)/(S)/(N) 1-16 stages - 10.0 bar,
1HM (S)/(N) 18-25 stages - 16.0 bar.
3HM (P)/(S)/(N) 1-13 stages - 10.0 bar,
3HM (S)/(N) 14-21 stages - 16.0 bar.
5HM (P)/(S)/(N) 1-13 stages - 10.0 bar,
5HM (S)/(N) 14-21 stages - 16.0 bar.
10HM (P)/(S)/(N) 1-8 stages - 10.0 bar,
10HM (S)/(N) 9-13 stages - 16.0 bar.
15HM (S)/(N) 2-7 stages - 10.0 bar,
22HM (S)/(N) 2-5 stages - 10.0 bar.
