Overview of Primary Product

Technical Data
BALANCE STANDARDS
Impellers are balanced to Hydraulic Institute Standards ANSI/HI 9.6.4-2009.
The allowable residual unbalance in the impeller rotating assembly conforms to
ANSI grade G6.3 (Ref. ISO 1940).
ANSI Balance Quality Grades of G2.5 and G1 for the rotating assembly are also
available. Consult your local Bell & Gossett Representative for additional details.
VIBRATION LIMITS
Series 1510 pumps conform to Hydraulic Institute ANSI/HI 9.6.4-2009 for recommended
acceptable unfiltered field vibration limits (as measured at the pump bearings per
ANSI/HI 9.6.4-2009, Figure 9.6.4.2.3.1) for pumps with rolling contact bearings.
SEISMIC CAPABILITIES
Series 1510 pumps are capable of withstanding a horizontal load of 0.5g*
without adversely affecting pump operation.
*Piping and/or fasteners used to anchor the pump to the mounting pads on the floor are excluded.
