Goulds Pumps 3409 - IOM - Manual (Page 30)

FREEZE PROTECTION
Pumps that are shut down during freezing conditions
should be protected by one of the following methods.
1. Drain the pump; remove all liquid from the casing.
2. Keep fluid moving in the pump and insulate or heat the
pump to prevent freezing.
$
CAUTION
If heat is used to keep the pump from freezing, do not
let the temperature rise above 150° F.
FIELD TESTS
A typical performance curve for a specific pump can be
obtained from Goulds Pumps. This can be used in
conjunction with a field test, if one is required. Goulds
Pumps tests and curves are based on the Hydraulic Institute
Standards. Any field test must be conducted according to
these Standards. Unless otherwise specifically agreed, all capacity, head,
and efficiencies are based on shop tests when handling
clear, cold, fresh water at a temperature not over 85° F.
The Appendices contains a field test report sheet and some
useful equations which can be used when conducting a
field test.
