Description and Specifi cations
The Model HMS is a close coupled, end suction, multistage centrifugal pump for general liquid transfer service,
booster applications, etc. Liquid-end construction is all
AISI Type 316 stainless steel, stamped and welded.
Impellers are fully enclosed, non-trimmable to
intermediate diameters. Casings are fi tted with diffusers
for effi ciency and for negligible radial shaft loading.
All units have NEMA 48Y or 56Y motors with square
fl ange mounting and threaded shaft extension.
1. Important Instructions
1.1 Inspect unit for damage. Report any damage to car-
rier/dealer immediately.
1.2 Electrical supply must be a separate branch circuit with
fuses or circuit breakers, wire sizes, etc., in compliance
with National and Local electrical codes. Install an allleg disconnect switch near pump.
CAUTION: ALWAYS DISCONNECT ELECTRICAL
POWER WHEN HANDLING PUMP OR
CONTROLS.
1.3 Motors must be wired for proper voltage. Motor
wiring diagram is on motor nameplate. Wire size must
limit maximum voltage drop to 10% of nameplate
voltage at motor terminals, or motor life and pump
performance will be lowered.
1.4 Always use horsepower-rated switches, contactor and
starters.
1.5 Motor protection
1.5.1 Single-phase: Thermal protection for single-phase
units is sometimes built in (check nameplate). If no
built-in protection is provided, use a contactor with a
proper load. Fusing is permissible.
1.5.2 Three-phase: Provide three-leg protection with
properly sized magnetic starter and thermal overloads.
1.6 Maximum Operating Limits:
Liquid Temperature: 230ºF (110ºC)
Working Pressure to: 125 PSI (8 Bar)
Starts per Hour: 20, evenly distributed
1.7 Regular inspection and maintenance will increase
service life. Base schedule on operating time. Refer to
Section 8.
2. Installation
2.1 Locate pump as near liquid source as possible (below)
level of liquid for automatic operation).
2.2 Protect from freezing or fl ooding.
2.3 Allow adequate space for servicing and ventilation.
2.4 All piping must be supported independently of the
pump, and must “line-up” naturally.
CAUTION: NEVER DRAW PIPING INTO PLACE BY
FORCING THE PUMP SUCTION AND
DISCHARGE CONNECTIONS.
2.5 Avoid unnecessary fi ttings. Select sizes to keep friction
losses to a minimum.
2.6 Units may be installed horizontally, inclined or
vertically.
CAUTION: DO NOT INSTALL WITH MOTOR
BELOW PUMP. ANY LEAKAGE OR
CONDENSATION WILL AFFECT THE
MOTOR.
2.7 Foundation must be fl at and substantial to eliminate
strain when tightening bolts. Use rubber mounts to
minimize noise and vibration.
2.8 Tighten motor hold-down bolts before connecting
piping to pump.
3. Suction Piping
3.1 Low static suction lift and short, direct, suction piping
is desired. Consult pump performance curve for Net
Positive Suction Head Required.
3.2 Suction pipe must be at least as large as the suction
connection of the pump. Smaller size will degrade
performance.
3.3 If larger pipe is required, an eccentric pipe reducer
(with straight side up) must be installed at the pump.
3.4 Installation with pump below source of supply:
3.4.1 Install full fl ow isolation valve in piping for
inspection and maintenance.
CAUTION: DO NOT USE SUCTION ISOLATION
VALVE TO THROTTLE PUMP.
3.5 Installation with pump above source of supply:
3.5.1 Avoid air pockets. No part of piping should be
higher than pump suction connection. Slope piping
upward from liquid source.
3.5.2 All joints must be airtight.
3.5.3 Foot valve to be used only if necessary for
priming, or to hold prime on intermittent service.
3.5.4 Suction strainer open area must be at least triple
the pipe area.
3.6 Size of inlet from liquid source, and minimum
submergence over inlet, must be suffi cient to prevent
air entering pump through vortexing. See Figures 1-4.
3.7 Use 3-4 wraps of Tefl on tape to seal threaded
connections.

4. Discharge Piping
4.1 Allowance should be made for disconnecting discharge
piping near casing to allow for pump disassembly.
4.2 Arrangement must include a check valve located
between a gate valve and the pump. The gate valve
is for regulation of capacity, or for inspection of the
pump or check valve.
4.3 If an increaser is required, place between check valve
and pump.
4.4 Use 3-4 wraps of Tefl on tape to seal threaded
connections.
5. Rotation
5.1 Correct rotation is right-hand (clockwise when viewed
from the motor end). Switch power on and off quickly.
Observe shaft rotation. to change rotation:
5.1.1 Single-phase motor: Non-reversible
5.1.2 Three-phase motor: Interchange any two power
supply leads.
6. Operation
6.1 Before starting, pump must be primed (free of air and
suction pipe full of liquid) and discharge valve partially
open.
6.2 Make complete check after unit is run under operating
conditions and temperature has stabilized. Check for
expansion of piping.
7. Maintenance
7.1 Ball bearings are located in and are part of the mo-
tor. They are permanently lubricated. No greasing
required.
CAUTION: PUMPED LIQUID PROVIDES
LUBRICATION. IF PUMP IS RUN DRY,
ROTATING PARTS WILL SEIZE AND
MECHANICAL SEAL WILL BE
DAMAGED. DO NOT OPERATE AT OR
NEAR ZERO FLOW. ENERGY IMPARTED
TO THE LIQUID IS CONVERTED INTO
HEAT. LIQUID MAY FLASH TO VAPOR.
ROTATING PARTS REQUIRE LIQUID TO
PREVENT SCORING OR SEIZING.
8. Disassembly
8.1 Complete disassembly of the unit will be described.
Proceed only as far as required to perform the
maintenance work required.
8.1.1 Turn off power.
8.1.2 Drain system and fl ush if necessary.
8.1.3 Disconnect discharge pipe from pump.
8.1.4 Remove motor hold-down bolts.
8.2 Disassembly of liquid end
8.2.1 Drain the pump body through the drain plug (4).
8.2.2 Remove the casing screws (1) from the motor
adapter (17).
8.2.3 Remove the pump body (2) and the o-ring (15)
located between the pump body and the seal
housing (16).
8.2.4 Remove motor fan cover (24) to expose wrench
fl ats or slot on shaft end.
CAUTION: DO NOT INSERT SCREWDRIVER
BETWEEN THE FAN BLADES TO
PREVENT ROTATION.

8.2.5 Hold motor shaft at fl at or slot to resist rotation
and remove impeller nut and washer (5, 6).
8.2.6 The following parts can now be removed from
the pump shaft in sequence: Diffuser with o-ring (7,
9), impeller spacer (8),impeller (10), impeller spacer
(8), etc. until the complete “hydraulic element” is dismantled. Note: Each diffuser contains an o-ring (9).
8.2.7 Remove the shoulder washer (13) from the
pump shaft (18).
NOTE: Further disassembly will require removal of the
mechanical seal. It is recommended that a new
mechanical seal be installed at reassembly.
8.2.8 Carefully pull the rotary portion of the mechanical seal (14) from the shaft coupling (19).
8.2.9 Remove the seal housing (16) from the motor
adapter. The stationary portion of the mechanical seal
(14) can now be removed from the seal housing.
8.2.10 Remove the motor screws (21) from the motor
adapter and remove the motor adapter from the motor.
8.2.11 To remove the pump shaft (18) from the shaft
coupling (19), heat must be applied to the small end
of the shaft coupling. This is required to break the
bond of the Loctite #271 between the pump shaft and
coupling.
CAUTION: DO NOT DAMAGE THE SMALL END OF
THE SHAFT COUPLING WHERE THE
MECHANICAL SEAL SITS.
Hold the motor shaft at fl ats or slots to resist rotation.
Repeat for removal of the shaft coupling from the motor shaft, this time heating the large end of the shaft
coupling.
9. Reassembly
9.1 All parts should be cleaned before reassembly. Remove
all cured Loctite from parts using denatured alcohol
and wire brush. Allow parts to dry before reassembly.
9.2 Refer to parts list to identify required replacement
items. Specify pump index or catalog number when
ordering parts.
9.3 Reassembly is the reverse of disassembly.
NOTE: The impeller spacers must be assembled with the
larger diameter edge adjacent to each impeller.
The last stage diffuser (12) can be identifi ed from
the standard by the holes around its circum ference,it is recommended that one of these holes
be lined up with the discharge port. Fix the
hydraulic element by tightening the impeller screw
(5) and impeller washer (6) with a torque setting
of 10 ft. Position the o-ring (15) on the
mechanical seal housing (16), locate the pump
body (2) and fi t it to the motor adapter (17) with
the four screws (1).
Observe the following when reassembling the pump:
9.4 Check for motor shaft runout. Maximum permissible
is .002" TIR.
9.5 Apply Loctite ‘Primer 7649’ and allow 2-3 minutes to
dry. Next apply Loctite #271 to motor shaft, thread
coupling shaft in place and torque to 15 ft. of torque.
9.6 Apply Loctite ‘Primer 7649’ and allow 2-3 minutes to
dry. Next apply Loctite #271 to pump shaft. Thread
pump shaft in place and torque to 15 ft. of torque.
9.7 Check pump shaft runout. Maximum permissible is
.010 TIR.
9.8 Lubricate shaft coupling and seal housing stationary
seat holder with a 50/50 glycerin and water solution
prior to installation of mechanical seal components.
9.9 Apply Loctite "Primer 7649" and allow 2-3 minutes
to dry. Then apply Loctite #243 to impeller bolt (5).
Thread bolt into pump shaft and torque to 10 lb. ft. of
torque.
9.10 Inspect casing o-ring (15) and impeller o-rings (9) for
damage or wear and replace if necessary.
9.11 O-rings may be lubricated with glycerin and water
solution or petroleum jelly to ease assembly.
9.12 Tighten casing screws to 15 lb.ft. of torque using a
star pattern to prevent o-ring binding.
