ATTENTION: SAFETY WARNINGS:
Model 1590F pumps are furnished with packing and lantern
ring when suction pressure is 30 PSIG or less and packing only
when suction pressure is greater than 30 PSIG.
LOCATION:
The pump should be installed in a clean, heated and well
ventilated area that allows access for inspection, cleaning and
proper maintenance. Sufficient space should be provided for
installation and removal.
MOUNTING:
Model 1590F pumps have been designed with an assembled
column base to support the pump and motor. The column base
may be floor mounted or mounted to another base.
PIPING:
Suction and discharge piping must not be smaller than the inlet
and outlet piping sizes of the pump. Piping connections must be
tight, particularly the suction, as air leakage can cause reduced
capacity or loss of prime. Isolation valves should be provided in
suction and discharge lines.
Check the pump for pipe strain. Forcing the pipe to align
with the pump flanges or inadequate support of suction
and discharge piping can result in binding of the rotating
element. Failure to conform to these precautions can result
in malfunction or damage to the pump and motor
ELECTRICAL SAFETY:
HIGH PRESSURE SAFETY:
WIRING AND CONTROLS:
Power supply connection to controls and motors must conform
with national and local codes. Line voltage and wire capacity
must agree with the ratings of the motor nameplate.
IMPELLER ROTATION:
Prime pump before starting the motor or damage can occur
to close clearance rotating parts. Bleed all air from the pump
casing and suction pipe by opening the pipe plug located on the
discharge nozzle. If accessible, rotate shaft slowly to evacuate
air trapped in the impeller passages.
Jog the motor to check that the motor shaft rotates clockwise,
as indicated by the arrow on the pump casing. If rotation is
counterclockwise, correct by changing two wire leads.
OPERATION:
Before starting the pump:
1. Check that the current supply agrees with the voltage and
frequency of the motor nameplate.
2. Check that the motor is wired for correct voltage.
3. Check that thermal overload relays are correct size and
set for operation.
4. Check that suction line valve is open and discharge line
valve closed.
After starting the pump:
Check that the pump is operating smoothly and is not rubbing,
which could be caused by pipe strain.
The pump is provided with a circulation relief valve that
prevents overheating when the pump is operating at reduced
capacity. The suction valve should be full open and not be
used for flow regulation. The discharge valve is used for flow
regulation. Open the discharge valve slowly and check that pipe
connections are sealed.
CAUTION
Warning: Electrical Shock Hazard
All electrical connections are to be made by a qualified elec-
trician in accordance with all codes and ordinances. Failure
to follow these instructions could result in serious personal
injury, death or property damage.
Warning: Electrical Overload Hazard
Insure all motors have properly sized overload protection.
Failure to follow these instructions could result in serious
personal injury, death or property damage.
Warning: Sudden Start-Up Hazard
Disconnect and lock out power source before servicing.
Failure to follow these instructions could result in serious
personal injury, death or property damage.
Warning: High Pressure Hazard
The pump is rated at a maximum of 175 psi at 150°F. Do
not exceed this pressure. Install properly sized pressure
relief valves in system. Failure to follow these instruc-
tions could result in serious personal injury, death or
property damage.

TROUBLESHOOTING:
If motor fails to start:
1. Wrong voltage, wiring hook up incorrect. Switches
not set.
2. Rotating element may be bound due to clog in impeller
pipe strain.
3. Tripped thermal overload relay or blown fuses.
4. Starter contacts may be shorted or corroded.
Terminal connections may be broken at some point
in the circuit.
Lost prime:
1. Suction pressure too low.
2. Leaks in suction piping connections.
3. High level of air entrainment.
Low or no water flow:
1. Speed may be low; check for low voltage.
2. The impeller may be clogged or damaged or suction
and discharge lines partially clogged.
3. Valves may not be fully open.
4. Pump not primed.
5. Suction pressure may be low.
6. Required discharge pressure may be greater than
originally anticipated.
Noise or vibration:
1. Partially clogged impeller resulting in imbalance.
2. Cavitation, net positive suction head available is too low.
3. Pump fully primed.
4. Foundation improperly secured or not strong enough.
5. Piping not anchored securely.
6. Rotating element binding due to damaged shaft worn
bearings or pipe strain.
1BACK PULL-OUT CASING with
inline suction and discharge.
2CASE WEARING RING prevents
wear on casing and is easily and
inexpensively replaced.
3SUPPORT simplifies mounting. The
pump can be fastened to the floor, a
base or foundation.
4DYNAMICALLY BALANCED
IMPELLER is keyed to the shaft and
secured by a capscrew and washer.
Vacuum casting and quality controlled
manufacturing process assures
consistent high performance. Enclosed
design provides high efficiency and
low wear for long service life.
5CARBON STEEL SHAFT is designed
for minimum deflection at maximum
load.
6TWO PIECE BRONZE PACKING
GLAND provides easy packing
maintenance.
7FACTORY PERFORMANCE TEST
guarantees performance at specified
pump operating conditions.
8FLUSH LINE with valve (when used)
from discharge provides easy water
seal adjustment to lantern ring.
9BRONZE SHAFT SLEEVE extends
full length of stuffing box to protect
motor shaft. The shaft sleeve is slip fit
over the shaft and then is keylocked.
Shaft sleeve and impeller screw are
sealed by O-ring gaskets to eliminate
corrosion of the shaft by the pumped
liquid.
10 STANDARD MOTOR approved for
1590F Series pump service by NEMA
and the HYDRAULIC INSTITUTE
provides low noise level pump
operation.
11 VOLUTE TYPE SUCTION inlet
prerotates suction liquid.
