Manual

À With 250# FF flanges and 280# PSIG working pressure refer to
pump as M2 x 3-11S.
- With 250# FF flanges and 400# PSIG working pressure refer
to pump as H2 x 3-11S.
® For pumps with 400 PSI working pressure, wear ring clearances are
doubled. Derate pump efficiencies by 2 percentage points.
¯ Flange dimensions are in accordance with ANSI A21.10, AWWA
C110 & ANSI B16.1 Class 125.
° Flange dimensions are in accordance with ANSI B16. 1 class
250 except flanges are flat faced, i.e. FF.
± The hydrostatic test will be in accordance with the latest edition of the
Hydraulic Institute Standards, test will be maintained for a minimum of
5 minutes.
² Type 1 and 21 seals have the same working lengths.
³ 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.
µ Balanced mechanical seals have a major diameter and a minor diameter as listed.
Not available in mechanical seal on shaft arrangement.
