Carbonator-Mount Rotary

Close-Coupled External Gear Pumps

Refer to form L-4082 for General Operating and Safety Instructions.

Description

Shertech self-priming, positive displacement, external rotary gear pumps are ideal for a wide range of intermittent and

light-duty industrial, marine, agricultural, and commercial applications, providing a nearly pulseless flow. Close-coupled

models are available directly mounted to NEMA framed, AC ODP single-phase, thermally overload-protected motors or as

pump heads only for custom installations. All models include a pressure relief valve. Motor-driven models are HP configured to

handle up to 500 SSU at 100 psi (specific gravity of 1.0).

Uses: For use with non-particulate and non-abrasive fluids compatible with pump wet-end construction component materials.

• Flows to 4.4 GPM.

• Max. RPM: 1725.

• Max. PSI: 100.

• Maximum viscosity of 500 SSU at 1725 RPM (max. input torque of 45 in.-lbs.).

• Pumps can operate bi-directionally (reversible). In reverse operation, the pressure relief valve will not function.

• Temperature ranges from -20° to 210° F.

• Maximum working pressure: 150 PSI.

CARBONATOR-MOUNT CAST IRON PUMPS (INTERMITTENT DUTY) – Specifically designed for use with oil-based fluids. Not

to be used with water-based fluids. Pumps include steel spur gears with steel shafts and cast iron shaft support; standard

pressure relief valves that can be ported internally or externally and a Viton mechanical carbon/ceramic-faced seal with

temperature range of 32° to 280° F. Wet-end parts are constructed from cast iron, steel, stainless steel (302, 303 and/or 18-8),

carbon, ceramic, and Viton.

CARBONATOR-MOUNT BRONZE PUMPS (INTERMITTENT DUTY) – Excellent for water-based fluids. Feature 303 stainless steel

shafts, carbon graphite bushings, and Buna-N mechanical carbon/ceramic faced seal with a temperature range of -20° to 210° F.

Standard pressure relief valves can be ported internally or externally. Wet-end parts are constructed from bronze, brass,

stainless steel (302, 303 and/or 18-8), graphite, carbon, and Buna-N.

PUMP HEADS (NO MOTOR) – Close-coupled gear pump heads are designed to direct couple to carbonator pump motors

(See NEMA Spec. MGI-18.739, Dimensions of Carbonator Motor mounting). The face of this gear pump has been machined to

match the carbonator motor face. Pump and motor held together with a stainless steel beveled “V” band clamp. Coupling of

shafts is done by mating the carbonator motor’s slot with the pump’s slot using the Oldham coupling (See Figure 2). This positive

displacement characteristic offers a wide range of applications.

NOTE: See Rotary Gear Pump Selection Guide in the Motor Manual for suggestions concerning installation, selection, options,

and accessories.

WARNING: Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in flammable

and/or explosive atmospheres. When pumping hazardous or dangerous materials, use only in room or area designated for that

purpose. For your protection, always wear proper clothing, eye protection, etc. in case of any malfunction. For proper handling techniques

and cautions, contact your chemical supplier, insurance company and local agencies (fire dept., etc.). Failure to comply with this warning

could result in personal injury and/or property damage.

1. Refer to Figures 2 and 3.

For your protection, always wear proper

clothing, eye protection, etc. in case of any

malfunction. For proper handling techniques

and cautions, contact your chemical supplier,

insurance company and local agencies (fire

dept., etc.). Failure to comply with this

warning could result in personal injury

and/or property damage.

2. Remove the hex head machine

shafts and Oldham coupling (Ref.

No. 24, Figure 7). NOTE: The small

end of coupling goes into pump.

Installation

PIPING

IMPORTANT: In any installations where

property damage and/or personal

injury can occur when the pump is

not operating due to power outages,

discharge line freezing, or any other

reason, a back-up system(s) and/or

warning system(s) should be used.

SUCTION

1. Avoid excessive lengths or number of

fittings and bends in the suction line.

Rotation: When looking at the motor

shaft end, proper motor pump rotation

is clockwise (CW). Flow is left to right

(See Figure 3). Reverse the flow by

rotating the pump 180˚. Standard mod-

els are equipped with pressure relief

valves. It is important that the relief

valve be on the discharge side of the

pump. NOTE: Pump can be rotated 360°.

2. Attach suction line to suction inlet.

3. It is recommended that same size

pipe as pump ports be used or, in

cases requiring lengthy piping, the

next larger size pipe be used.

In order to safely use this product, familiar-

ize yourself with this pump and also with

the liquid (chemical, etc.) that is going to

be pumped through the unit. This pump is

not suitable for many liquids.

4. If suction lift is greater than what is

indicated in the performance chart,

attach a foot valve below liquid

level at end of suction line to ensure

positive priming. Also note: If fluid

specific gravity is greater than 1.4 or

viscosity greater than 500 SSU, a

foot valve is also recommended.

1. Locate the pump as close to the

liquid source as possible, making

the suction line as short and direct

as possible.

5. Slip the ”V“ band clamp over the

pump and motor halves (See Figure

2) and tighten the hex head clamp

screw to hold the assembly together.

Ambient

temperature around

motor should not exceed 104˚F (40˚C).

6. Retighten the ”V“band clamp screw

as necessary. Use thread sealant if

screw keeps coming loose.

5. If solid contaminates are suspected

in a liquid, place a filter in the

suction line.

tions are airtight.

loosen lock nut, then turn the set

screw (Figure 4 & 7, Ref. No. 18) in

pressure is achieved, tighten lock

nut and reinstall protective cap.

Operation

Do not run pump dry,

as permanent damage

NOTE: Assure airtight pipe connections

to the pump gears, seal, and bearings will

result. Suction pressure should never be

greater than the discharge pressure.

DISCHARGE

1. All pumps must be primed before

start-up. Never operate a pump

unless it is secured to a solid

foundation.

1. Attach discharge piping to the

discharge outlet.

8. The pressure relief valve can be

converted to an external relief. This

will allow the relief to dump back

to tank and allow longer periods of

relief without pump damage.

However, this is not a full-line relief

valve, and in cases where frequent

extended relief valve operation is

anticipated, a full-line size relief

valve should be piped in the dis-

charge line and connected either

back to the tank or well down-

stream of the pump suction inlet.

Support pump and

piping during assem-

bly and after installation. Failure to do so may

cause piping to break, pump to fail, motor

bearing failures, etc. All of which can result

in property damage and/or personal injury.

2. Gear pumps are built to very close

tolerances and this tolerance must

not be altered. The liquids must,

therefore, be free of all abrasives.

Sand, silt, wettable powders, etc.

must be avoided.

NOTE: Should the pump need to be

self-draining, the pump head should be

mounted in the vertical position with

the suction port facing down. When

pumping high viscosity fluids, the

vertical position can be used with the

suction port facing up and the pump

mounted under the source. Increasing

the suction pipe size and eliminating

bends and elbows also assists in pump-

ing high viscosity fluids. Max. viscosity is

500 SSU at 1725 RPM.

NOTE: Cast iron pumps are for oil-based

fluids only.

3. When pumping a more viscous

(beyond 500 SSU) liquid, a slower

speed, a larger pipe size pump,

and possibly a larger motor should

be selected.

2. If a shut-off valve or handgun is

required in discharge line, provide

a pressure relief valve for pump

protection.

Figure 4 - Pressure

Relief Valve Adjustment

9. To convert the relief valve to exter-

nal relief, remove the 1/4 NPT pipe

plug from the pump cover (Figure 5

& 7, Ref. No. 13) and discard. This

plug is next to the relief valve. In

the bottom of the 1/4 NPT hole,

there is a second drilled and tapped

5. On all models, the pressure relief

valve is always on discharge side

(See Figure 3).

Shutting off

discharge without

providing pressure relief can cause extreme

over-pressure which can result in pump

and/or motor failure. Do not exceed 100 PSI

pump or system pressure.

PRESSURE RELIEF VALVE

6. Standard model rotary gear pumps

are supplied with a built-in pressure

relief valve. The valve may be adjust-

ed and used to set system operating

pressure, or used as a system relief

valve to prevent pump and motor

damage that can occur when dis-

charge line is closed off. This relief

valve is not factory set. Extended

operation (over one minute) under

shut-off conditions could cause pump

to overheat, leak, and damage itself.

3. Operation under shut-off discharge

conditions will overheat and

damage pump.

Optional

external

bypass plug

NOTE: Globe valve or other restrictive

valves should not be used as shut-off

mechanism as they are restrictive in

nature and will seriously affect pump

performance.

4. After all piping and controls (not

supplied with unit) have been

installed, unit is ready for operation.

Remove and

discard plug

7. To increase the relief valve pressure

setting, remove protective cap,

nal bypass plug (Figure 5 & 7, Ref.

No. 14 included) should be inserted

in this hole and bottomed out. The

open 1/4 NPT port must now be

piped back to the tank or well

nected before attempting to service or disas-

semble any components! If the power discon-

nect is out of sight, lock it in the open position

and tag to prevent application of power.

DISASSEMBLY AND ASSEMBLY

GENERAL

downstream of the pump suction.

Refer to Figure 7 for parts identification

during disassembly and assembly.

[Assumes pump is separated from

motor and that Oldham coupling

(Ref. No. 24) is removed.]

Check the pump for proper operation

daily, weekly, monthly, etc. If anything

has changed (pump noise, motor noise,

leaks, etc.) since the pump was new, the

pump should be removed, examined and

repaired if necessary. This is a difficult

motor/pump to repair, therefore, only

qualified electricians or service techni-

cians should attempt to repair this unit.

Improper repair and/or assembly can

cause problems with the electric motor

used with this unit. See General Safety

Information.

10. For operation of the pump with

pressure relief valve in reverse rota-

tion, the motor may be reversed,

allowing for reverse rotation.

Standard models are equipped with

pressure relief valves and the pump

can be run in reverse, however, the

pressure relief valve will not func-

tion. For continuous reverse rota-

tion, the cover plate must be rotat-

ed 180˚. This is accomplished by

removing the six cover plate screws,

rotating the cover plate, and reat-

taching the screws. The relief valve

should now be on the opposite side.

This will allow operation of the

pump with a functioning pressure

relief valve in reverse rotation.

1. Remove screws (Ref. No. 3) and

cover (Ref. No. 2). Refer to

INSPECTION procedures below.

2. Lift out idler shaft (Ref. No. 8).

3. Remove internal retaining ring (Ref.

No. 12) from drive end of the pump

body (Ref. No. 1) using TruArc-type

internal snap-ring pliers.

Retighten the ”V“ band clamp screw as

necessary. Use Loctite or similar thread

sealant if screw keeps coming loose.

4. Carefully pry out ceramic seat (Ref.

No. 11) and then seal (parts of

seal seat assembly using a suitable

hooked tool).

Rotary gear pumps must be drained

completely if subject to freezing

temperature and should not be

operated until temperature permits.

touching either of the seal faces.

Scratching the seal faces will cause

the seal to leak. Using anything

other than water as a lubricant,

when installing seal and seat, may

cause seal to leak.

5. Remove the seal assembly spring

and metal seat.

Do not run pump

dry, as permanent

damage to the pump gears, seal, and

bearings will result. Suction pressure should

never be greater than the discharge pressure.

6. Remove external retaining ring (Ref.

No. 9) from the shaft (Ref. No. 5)

using external snap-ring pliers

(2¹⁄2” legs).

NOTE: The carbon and ceramic seal

faces spin against each other providing

for the functional seal. The seal ceramic

seat o-ring is not the functional seal,

but its purpose is to hold the seal

ceramic seat in place.

7. Remove the gear assembly and drive

shaft (Ref. No. 4 & 5).

Pump Inspection

Inspect components for signs of

excessive wear.

5. Reinstall the snap ring (Ref. No. 12).

Excessive wear of the pump will usually

show up as degradation of performance.

This can be seen by the flow dropping

off under pressure, excessive noise

and/or excessive wear inside the pump.

Gear pump components are precision

fit. When the gears are worn, so is the

body, shafts, bushings or shaft pockets

and housing. At that point, the pump

head should be replaced.

2. Remove the spring (Ref. No. 22)

and piston (Ref. No. 23). A worn

or broken relief valve is a sign of

excessive pump wear. The pump

head should be replaced.

8. Assemble the pump in reverse order

of disassembly. Tighten cover screws

(Ref. No. 3) in opposing sequence.

As the cover (Ref. No. 2) is incre-

mentally tightened, the shaft

(Ref. No. 5) should be periodically

turned. This ensures cover-to-body

alignment and prevents binding

of shaft.

3. Reinstall new mechanical seal (Ref.

No. 10) on drive shaft using water as

a lubricant. Do not push on carbon

face of new mechanical seal. Push

with a hallowed out wood dowel or

piece of cardboard.

3. Assemble the relief valve in reverse

order.
