Functions of Nordstrom Valve Sealants

1. Drop-Tight Seal - To secure an absolutely tight seal,

the film of the sealant works to form a seal between the
sealing surfaces of the valve. The seal is formed by sealant
transmitted through a system of passageways around the
valve port. With proper selection of sealant for your particular
service, the seal can be retained over a wide range of temper­atures and pressures.

2. Lubrication - Prevents metal-to-metal contact of the valve

sealing surfaces by filming over bearing irregularities. No
matter how finely ground a metal surface may be, the metal is
a series of tiny peaks and valleys. As one metal surface slides
against another, friction is set up and adhesion, shearing,
or plowing may result. A protective film of sealant over the
bearing area prevents metal-to-metal rubbing.

3. Renewable Seat - There is no need to disassemble a

lubricated valve or remove it from service to replace mildly
damaged seats. Sealant, as a structural part of lubricated
valves, provides a flexible and renewable seat, eliminating
the necessity of force fit contact to effect a seal. For this
purpose, the sealant not only must have proper plasticity, but
also resistance to line fluids such as solvents and chemicals.
Sealant forms a seal between the sealing surfaces of the valve
even under pressure.

4. Plug Jacking - The fundamental operating principle of the

traditional lubricated plug valve design lies in the application
of Pascal’s Law. The law states that a unit pressure applied to
the liquid contained in a sealed vessel is transmitted to every
part of the liquid with undiminished force, thus multiplying
the force many times, depending on the area of the interior of
the vessel. The sealant, under pressure developed by sealant
injection, supplies the hydraulic means for lifting the plug
from its tapered seat when and if that force is needed to
free the plug.

Nordstrom Valves offers
more than twenty five
varieties of sealants
for plug, ball, and gate
valves. Stick and bulk
grades are available in
most formulas.

Hypregun-Plus 5Q

Flow Control

Nordstrom Valves

The Flowserve Nordstrom Hypregun-Plus 5Q was developed
using the original Nordstrom Hypregun design and modifications
as suggested by many Hypregun owners. This design continues to
meet field and plant maintenance needs of valve users.
The Hypregun-Plus 5Q is ideal for large scale valve servicing
in refineries, compressor stations, gasoline plants, cycling plants,
pipelines, and manifold installations.
The Hypregun-Plus 5Q is a compact, highly efficient, air
operated sealant injection device with a 100:1 pressure ratio,
double acting piston, and five quart can. Continued positive
pressure applied to the side cylinders assures intimate contact
between the follower plate and sealant. Positive pressure makes
it possible for the Hypregun-Plus 5Q to pump sealant at a much
lower temperature than is possible with dispensing equipment
without this feature.
The follower plate is engineered to promote flow of sealant
to the foot valve at all workable air pressures, but air pressures
between 100 and 125 psi (6.9 to 8.6 bar) give the most efficient
operation. Lower air pressure can be used but the gun delivery
volume will be reduced accordingly. It is important that the gun
not be used on air pressures exceeding the 125 psi (8.6 bar)
rating of the air motor. The air motor uses a maximum of 11.4
cubic feet of air per minute when operated at 125 psi (8.6 bar) air
pressure and with zero load. Reduced air pressure and increased
load reduce air consumption although not linearly.
The amount of sealant delivered by the Hypregun-Plus 5Q
depends on available air pressure to the gun, type of sealant and
the temperature at which the sealant is dispensed.
A moisture trap (not supplied with the gun) for use on
air sources containing appreciable amounts of water is quite
advantageous for low temperature applications. Moisture, if
allowed to reach the air motor, can condense and freeze, causing
the air motor to stall. Air line filters for removing moisture from
the air supply are available from several manufacturers.
The Hypregun-Plus 5Q is designed to use five-quart
(4.7 litre) sealant cans, which have been materially strengthened
with welded seams. These cans are standard containers for all
Nordstrom bulk sealants. The can shield supplied with each gun
gives added strength to the can.
The five-quart (4.7 litre) can and shield have been developed
specifically for use with the Hypregun-Plus 5Q. We do not
recommend using other containers or sealants developed
by other manufacturers.

How to get the most out
of your Hypregun-Plus 5Q

The following suggestions will ensure efficient and continued
operation of the gun:

• If the air motor operates slowly because of low temperatures or
other causes, introduce light machine oil into the motor through
the air supply. This will, in most cases, free a stalled air motor
and permit it to operate more efficiently.

• Remove any service sealant from the exposed portion of the
pumping mechanism to reduce drag and prevent sealant from
entering portions of the gun not designed for this purpose.

• Provide a means of removing moisture from the air supply
to the gun if used at subfreezing temperatures. Use of air
filters should accomplish
this purpose.

• Do not damage the thin walled cylinder surrounding the piston
of the air motor. Any imperfection in this cylinder will reduce
the effectiveness of the gun and shorten its life.

washer (83), and nut (86). The lock washer is to be positioned
between the base and nut.

5. Tighten firmly using the adjustable wrench and socket.

6. Locate the kick stand mounting hole on the back of the base
(18).

7. Align the hole in the kick stand with the
hole in the yoke.

8. Secure the kick stand into position
using capscrew (87), washer (82),
spring (76), lock washer (83), and nut
(85). The washer (82) is to be placed
on the capscrew and the spring against
the washer. This assembly is to be
placed through the kick stand and base
holes. Install the lock washer and hex
nut. The nut should be threaded onto
the capscrew until the threads appear
through the nut. If the nut is tightened
too much, the kick stand spring will be
too compressed to allow for free
movement of the kick stand.

9. Stand the Hypregun-Plus 5Q
upright and place the kickstand in
the down position.

Preparing the
Hypregun-Plus 5Q for Use

1. Using an adjustable wrench, install the hose assembly by
attaching the L-type swivel to the pump body (33).

2. Raise the follower (34) by connecting the air supply hose to the
nipple (57) located on the base (18) of the gun.

3. Remove the can shield (72) and install it on the five-quart (4.7
litre) can of Nordstrom valve sealant. To prevent the can from
splitting at the seam, the can shield should be installed with the
opening on the side of the can shield positioned opposite the
seam on the can. The top and bottom of the can shield should
not overlap the lip of the can.

4. Apply a coating of light machine oil to the follower wiper (35)
before loading the gun with a can of sealant. This will lubricate
the seal and allow for easy entry into the can.

5. The spring loaded kick stand is “kicked” to one side to allow
the gun to be tilted backward and rolled.

The numbers in parentheses refer to Hypregun-Plus 5Q parts as
illustrated on pages 5 and 6 of this manual.

1. The air coupler (17) will be found attached to the nipple (7)
as shown in Section A-A. The air hose connector should be
connected to the air supply hose.

2. Fasten the can shield (72, Figure 1) in place around the five­quart (4.7 litre) sealant can below the reinforcing rib and with
the can seam covered by the retainer.

3. Slightly mound the sealant in the container so that the
concave shaped follower plate can be brought down on the
sealant with a minimum entrapment of air.

4. Raise the pump mechanism and sealant follower plate prior
to inserting the sealant container into the gun. By connecting
the air supply hose to the air supply nipple (57, Figure 2) in
the base of the pump and opening the ram needle valve (8,
Section A-A) the follower (34, Figure 1) will rise sufficiently to
clear the top of the sealant container.

5. Place the can with the can shield in the operating position in
the Hypregun-Plus 5Q.

6. Be sure the valve screw (63, Figure 1) in the pump body is
closed. Connect the air supply hose to the nipple (7, Section
A-A). The ram needle valve should be opened slowly causing
the air pressure to force the follower plate (34, Figure 1) down
toward the sealant container.

CAUTION - Keep fingers clear as the follower plate

descends into the sealant container

Care should be exercised that the sealant container is

directly under the follower plate as the two are brought into
contact. Once the follower plate has entered the top of the
sealant container, open the ram needle valve 2 1/2 turns
from closed position.

7. As shown in Section B-B, the relief valve (64) is opened fully
while the valve screw (63, Figure 1) is opened two turns.

8. With the air motor throttle valve closed (3, Figure 1), allow
the column between the sealant container and relief valve
(64, Section B-B) to fill with sealant with the pressure of the
follower plate alone. After a steady flow of sealant is obtained
at the relief valve, open the throttle valve and pump sealant
through the vent valve until there are no air bubbles. (If the
available line pressure is not sufficient to push sealant through
the relief valve by the follower plate pressure alone, open the
air motor throttle valve before the sealant comes out the vent
valve.)

9. After venting of the air is complete, close the valve screw
(63, Figure 1) and the relief valve (64, Section B-B) and read
the pressure gauge (65, Figure 1). If the pressure gauge does
not read several thousand pounds sealant pressure, the relief
valve (64) and the valve screw (63) should be opened again
to allow further venting. Repeat this operation as required.

Occasionally, The Hypregun-Plus 5Q may become air bound
during operation. If this occurs, repeat the procedure for air
venting as outlined above.

10. With the shut-off and relief valve (78, Section B-B) in the
closed position, the button head coupler (69, Section B-B)
should be slipped over the button head fitting on the valve to
be injected. Open the shut-off valve (a small wrench may be
required). Adjust the air throttle valve (3, Figure 1) on the air
motor and observe sealant pressure on the gauge (65, Figure

1) to ensure proper sealant flow and pressure for plug valves.

WARNING - High pressure injection of sealant into

low pressure iron and semi-steel bodied valves
may deform or destroy certain valve parts which
could result in personal injury. Follow the valve
manufacturers recommended procedures for
sealant injection.

11. After the valve is injected with sealant, close the shut-off
and relief valve (78, Section B-B). Remove the button head
coupler (69, Section B-B) from the fitting on the valve. This
may be done without turning off the air supply to the air
motor. By using the shut-off valve, the user can attach the
coupler or remove it from the fitting with the gun retaining
positive pressure.

12. When all of the sealant has been pumped from the sealant
container, close the throttle valve (3, Figure 1) and transfer
the air supply hose to the air supply nipple (57, Figure 2) on
the base of the gun. With the ram needle valve (8, Section
A-A) open, the gun mechanism is raised, lifting the sealant
container off of the gun base. Close the ram needle valve.

13. Unclip the can shield and remove. Remove the can from the
follower. It may be necessary to attach the air supply to the
relief valve nipple (57, Section B-B) and slowly open the relief
valve (64, Section B-B) 1/4 turn to allow air to enter the can.
The can will be forced from the follower.

14. In changing from one service sealant to another, it is advisable
to purge the gun sealant system. To do this, pump the new
sealant through the delivery hose, with the coupler removed,
until the old sealant has been purged.

15. The pressure relief valve (4, Section A-A) is adjusted at the
factory to 125 psi (8.6 bar) cylinder pressure. Use of the
Hypregun-Plus 5Q at higher pressures can result in damage
to the gun.

16. The air motor is rated at 125 psi (8.6 bar). Do not use the
Hypregun-Plus 5Q on air pressures greater than this figure.
Lower air pressures are recommended where delivery capacity
will be adequate. Do not leave air pressure on the gun
indefinitely when not in use.

Care and Maintenance

Suggested
Hypregun-Plus 5Q Care

The following suggestions will ensure efficient and continued
operation of the Hypregun-Plus 5Q.

1. Avoid damage to the thin walled cylinder surrounding the
piston of the air motor. Imperfections in this cylinder will
reduce the effectiveness of the gun and shorten its life.

2. Handle the Hypregun-Plus 5Q with care. Prevent any bending
or denting of the pistons or operating parts.

3. Use a clean, dry air source. If air is wet, use a filter on the air
line to remove the water. Install an oiler in the air supply line
using light oil in summer and methanol in the winter.

4. Do not use over 125 psi (8.6 bar) air supply pressure. The
gun will work best between 100 psi (6.9 bar) and 125 psi
(8.6 bar).

5. Always use the can shield and five-quart (4.7 litre) cans that
are crimped and welded. The vertical welded seam on the
can should be placed opposite the opening on the shield. If
the opening on the shield is placed over the seam in the can,
the can seam may separate from the pressure created by the
piston.

6. CAUTION - When inserting a new five-quart (4.7 litre)

can of sealant, be extremely careful. Keep fingers
clear as the follower plate descends into the sealant
container.

Repair Reassembly

There are two places in the reassembly of the Hypregun-Plus
5Q pumping mechanism where the parts should not be rigidly
assembled:

1. When the piston and cylinder (42, Section C-C) are attached
to the air motor piston rod (37, Section C-C), they should only
be hand tight (not wrench tight), the holes aligned, and the
roll pin installed to secure in place.

2. In assembling the primer rod and foot valve assembly (45,
Section C-C) into the piston, it should be pinned in place
with roll pin (38, Section C-C) before it becomes tight. There
should be some “wobble” evident for self-alignment of the
parts. The primer rod and foot valve assembly (45, Section
C-C) and valve seat (47, Section C-C) should be replaced as
a single unit.

Factory Repair Service

Factory repair service is available from Flowserve Nordstrom
Valves. Consult your Authorized Distributor or Nordstrom
Customer Service for more details.

7. Be sure to bleed or vent the Hypregun-Plus 5Q before using.
The more the curvature of the mounded sealant matches the
curvature of the follower plate, the less air will be entrapped
when changing cans. The relief valve (64, Section B-B) should
be opened until a steady stream of sealant is obtained. If the
pressure gauge needle continues to bounce, remove the valve
screw (63, Figure 1) to free entrapped air in that area and, in
rare occasions, remove the pressure gauge to be sure there
is no air entrapped in the connection to it. Improper bleeding
is indicated by a very bouncy action of the pressure gauge
needle at relatively low pressures. If this continues, additional
bleeding is necessary.

8. Store the Hypregun-Plus 5Q and sealant in a reasonably warm
place so that not only the gun but the sealant is at an operable
temperature.

Sealant Delivery

Sealant Delivery

Hypregun-Plus 5Q sealant delivery is affected by the loading
pressure, ambient temperature, and the viscocity of the sealant
being pumped. The chart below provides laboratory test data
which illustrates sealant delivery under common operating
conditions. Also provided in the chart is comparison data
illustrating the improved performance of the Hypregun-Plus 5Q
over the Hypregun.
The Hypregun-Plus 5Q has also been tested for durability.
After 100 hours of continuous operation at atmospheric pressure
the Hypregun-Plus 5Q performed flawlessly.
Injecting sealant at ambient temperatures much lower than
that represented by the chart is accomplished by using the
practical approach of keeping the gun and sealant in a warm
place and only exposing them to extremely cold conditions
during valve injection.
