PUMP DESCRIPTION
The Model 3100 is a horizontal close-coupled
centrifugal pump. The pump is designed to utilize
standard NEMA JM motors.
The pump line is made up of six (6) hydraulic pump
sizes as follows:
S-Group: 1 x 1 1
2
- 6, 2 x 3 - 6, 1 x 1 1
2
- 8
M-Group: 2 x 3 - 8, 1 x 2 - 10, 2 x 3 - 10
Casing - the casing is a top centerline discharge
and is self-venting. Material of construction is cast
316 stainless steel (ASTM A743 CF8M). Flanges
are ANSI Class 150 flat face. The casing includes
integral foot supports to provide maximum
resistance to misalignment and distortion from pipe
loads.
Impeller - The impeller is an enclosed design which
is key driven by a NEMA JM motor shaft. Material of
construction is cast 316 stainless steel. The impeller
is held on the motor shaft by a cast 316 stainless
steel impeller nut which is sealed by a O-ring against
the face of the impeller to protect the motor shaft
from the pumpage.
Seal Chamber, Seal Chamber/Adapter - The seal
chamber is constructed of cast 316 stainless steel. A
tapered bore design is provided with four (4)
integrally cast axial ribs to maximize seal life. The
tapered bore design is self-venting. As standard a
machined internal seal flush is provided on all sizes
except the 6" S Group sizes to ensure positive
flushing of the mechanical seal. The seal chamber is
designed to accept a
John Crane Type 21
mechanical seal.
For S Group size pumps the motor adapter is
integral to the seal chamber. (S Group pumps may
be bolted to NEMA 140JM - 210JM motors)
Motor Adapter - A ductile iron motor adapter is
provided on M Group pumps only. The motor
adapter includes machined rabbetted fits and bolt
holes to facilitate bolting to NEMA JM 250 and
280/320 motor frames only! (M Group pumps
cannot be bolted to a NEMA motor frame smaller
than a NEMA 250JM)
Direction of Rotation - Clockwise (right hand) as
viewed from the motor end looking at the pump.
