3 DESCRIPTION
3.1 Configurations
The ESP3 vertical immersion sump pumps are
separately coupled metallic construction single stage
centrifugal pumps for wet pit applications. The ESP3
wetted parts are available in a wide range of
materials to handle most fluids. Vapor-tight, vapor-
proof, and pressurized construction options are
available. The hydraulics utilized are from Mark 3
chemical process pumps.
3.2 Nomenclature
The pump size will be engraved on the nameplate
typically as below:
2 E 6 X 4 SP - 13 A /12.5 RV
•
Frame size
“2" indicates a medium size pump frame (in this
example, a Group 2)
1 = Group 1 (small frame)
2 = Group 2 (medium frame)
3 = Group 3 (large frame)
•
Power end
E = ESP3 Pump
•
“6” = nominal suction port size (in.)
•
“4” = Nominal discharge port size (in.)
•
Modifier for “specialty pumps”
SP = standard sump pump
RSP = recessed impeller pump
LFSP = Lo-Flo pump
•

Pump design variation
A = This pump has been redesigned from an earlier
version. The impeller and casing are no longer
interchangeable with the earlier version.
H = This pump is designed for a higher flow capacity
than another pump with the same basic
designation. (Examples: 4X3-10 and 4X3-10H;
6X4-10 and 6X4-10H; 10X8-16 and 10X8-16H.
HH = This pump is designed for a higher head than
another pump with the same basic designation.
(Example: 4X3-13 and 4X3-13HH.)
