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.

Impeller is a light press fit on shaft, do not use construction with stainless steel

impellers.

Not available in mechanical seal on shaft arrangement.
