double suction type. The impeller shall be balanced,
keyed to the shaft and fixed in an axial position by
threaded shaft sleeves. The Impeller skirt shall be
grooved and fit with close tolerances to the casing ring to

and the casing ring for maximum efficiency. (Optional:
Renewable bronze impeller rings shall be shrunk on the
impeller and locked in place with stainless steel set
screws. The impeller rings shall be grooved and fit with
close tolerances to the casing ring for maximum
efficiency.)
4. Stuffing Boxes:
Packing - The stuffing boxes shall hold a minimum of
five rings of TFE packing. The bronze gland shall be split
in two halves, to facilitate removal for repacking. Gland
bolts shall be of the swing type made of steel with 18-8
stainless steel nuts.
Mechanical Seal - Sealing of the pump liquid cavity shall
be with a face type mechanical seal with Ni-resist
stationary seat, carbon sealing washer, Buna rubber
flexible members, stainless steel metal parts and spring.
Seal to be rated for 225o F .(107o C.) @ 150 psig
(10-34 bar) maximum. Mechanical seals shall be
mounted over bronze shaft sleeves.
GPM at a total head of feet,
% of design condition.

5. Shaft and Shaft Sleeves: The shaft shall be carbon
steel, adequately sized for the loads transmitted. Shaft
deflection shall not exceed .002 Inches at the face of the
stuffing box when operating between 95% and 105% of
capacity at best efficiency at the pump's maximum 60
Hz. speed and with full diameter Impeller. The shaft shall
be protected through the stuffing box by means of bronze
shaft sleeves and they shall be threaded against shaft
rotationand locked in place with set screws. The sleeves
shall be sealed with "O" rings at the Inside diameter to
eliminate leakage between the shaft and sleeve.
(Optional: Shaft shall be positively sealed against
pumped fluid by means of specially machined shaft
sleeves and Impeller with sockets for use with "O" ring
seals against Impeller hubs.) Shaft sleeves shall extend
beyond the packing glands (or mechanical seal flanges).
6. Bearings: Bearings shall be single row, deep groove ball
type; the inboard bearing shall be arranged for radial
loads only. The outboard bearing shall be arranged for
both radial and axial loads. Both bearings shall be
grease lubricated with grease flush through the bearing
housing (Optional: oil lube). Bearings shall be designed
for an average life of 100,000 hours.
Bearings shall be protected from liquid entry by means of
rubber deflectors mounted on the shaft and lip seals In
the bearing housings.
Outboard bearing cover shall have a plugged opening for
tachometer connection. Bearing housing lubrication
design must be capable of being changed from grease to
oil lubrication type without replacement of bearing
housing or the lower pump casing. The outboard bearing
shall have retaining ring retention.
7. Base: The pump and driver shall be mounted on a
common steel base (with optional drip rim). Pump and
driver shall be aligned and bolted In place prior to factory
shipment. Final alignment must be performed at the
jobsite In accordance with the standards of the Hydraulic
Institute and the pump Installation, operation and
maintenance instructions. Base Is to be grouted to
eliminate vibration.
8. Coupling: A flexible coupling shall be provided between
the pump and driver. A coupling guard shall be furnished
over the coupling for protection.

WORKING PRESSURE AND TEMPERATURE LIMITATIONS
The maximum working pressure of a pump varies with the temperature of the pumped fluid. Tables A and B and
Curve 4852154 on page 2.1 Section 1220, present the maximum working pressure and maximum suction pressure
limits for AE model pumps based on available flange drilling, casing material and fluid temperature.
IMPORTANT NOTE
The correct packing type, sleeve material or mechanical seal must be selected in accordance with their application
rules. The standard mechanical seals for AE pumps are limited to 150 psig (10.34 bar) maximum suction pressure
and temperature up to 225
o
F. (107
o
C.).
To verify that a given model AE pump is suitable for an application, the following steps must be taken.
STEP 1:
Calculate the pump's maximum discharge pressure (MDP).
For constant RPM applications:
MDP = [Total Head at Shutoff (for the impeller diameter and RPM required for rated total head) ÷ 2.31 x
fluid’s specific gravity] + suction pressure (psi) at zero flow.
STEP 2:
Locate the pump model in Table A and note the legend letter for the applicable pressure-temperature curve for
maximum working pressure allowed.
STEP 3:
Locate the pump model in Table B and note the legend letters for the applicable pressure-temperature curve for
maximum suction pressure allowed.
STEP 4:
o
Enter Curve 4852154 at the fluid temperature (
F.), read vertically to the curve line noted for the pump suction
and read the maximum permissible suction pressure.
Repeat this procedure for the discharge side to determine the maximum allowable working pressure.
STEP 5:
Relate the maximum suction pressure to the pump's permissible suction pressure and choose the suction flange
rating required. Repeat for the discharge flange.
EXAMPLE:
o
Model 4AE11, constant RPM, fluid temperature 70
F., suction pressure at 0 GPM = 85 psig, 1.0 specific gravity,
shutoff total head = 231 feet.
MDP = (231 ÷ 2.31 x 1.0) + 85 = 185 psi
4AE11 Discharge flange curve lines are E-E or D-D (from Table A)
4AE11 Suction flange curve lines are E-E or D-D (from Table B)
Maximum suction and discharge pressure for E-E = 175 psi, and D-D = 250 psi @ 70
Therefore: 125 lb. ANSI drilling for suction flange and 250 lb. ANSI drilling for discharge flange is required for cast
iron casing.

% Speed
Information required to use speed-torque curve
1 - 100% of Torque
2 - 100% of Speed = Rpm (true running speed)
To determine 100% of torque in Ft.-Lbs., use the following equation:
100% torque (Ft.-Lbs)
RPM (true running speed)
c For open valve starting - use BHP at design point
For closed valve starting - use BHP at shut-off point
= Ft.-lbs @ Gpm Total Head Feet
BHP c x 5250
