c With 250# FF flanges and 280# PSIG working pressure refer to pump as
M3x2x11S.
d With 250# FF flanges and 400# PSIG working pressure refer to pump as
H3x2x11S.
e For pumps with 400 PSI working pressure, wear ring clearances are doubled.
Derate pump efficiencies by 2 percentage points.
f Flange dimensions are in accordance with ANSI A21.10, AWWA C110 & ANSI
B16.1 class 125.
g Flange dimensions are in accordance with ANSI B16.1 class 250 except flanges
are flat faced, i.e. FF.
h The hydrostatic test will be accordance with the latest edition of the Hydraulic
Institute Standards, test will maintained for a minimum of 5 minutes.
i Type 1 and 21 seals have the same working lengths.
j For bronze impellers and casing rings. For diametral clearances for other
materials, consult factory.
l Impeller is a light press fit on shaft, do not use construction with stainless steel
impellers.
K Not available in mechanical seal on shaft arrangement.
