1.2 TIE BOLT TOQUE
The tie bolts on the pump are tightened before leaving the factory. However,
relaxation may occur due to handling, material creep, or other unforeseen
events. Trebor recommends that all eight tie bolts be re-tightened upon pump
install. The following procedure should be used.
1. Remove black tie bolt caps (Item 29 in 4.4 Parts Illustration) from both
sides of all 8 tie bolts.
2. Apply 32 in-lbs. of torque to each slave side bolt while holding the master
side bolt stationary. A star-pattern is advised.
a. The master side is the left side of the pump if you are looking at
the fluid ports.
3. Replace tie bolt caps.
1.3 UTILITIES / HOOK-UP
The pump is mounted using four 1/4” bolts. It is recommended that the pump be
mounted not more than 15from level to maintain its self-priming and pumping
efficiency.
NOTE: New pumps may contain residual moisture from their final DI water test.
Air Inlet: 1/4” FNPT (3/8” Dia. (8mm) supply tube minimum).
Air Supply: 20-60 psig (1.4 - 4.1 bar), clean dry air or nitrogen. (See Table 1:
Consumption / Efficiency for air consumption.)
Fluid Ports: 1/2” FNPT - additional adaptor port options available.
Inlet/Outlet adaptor fluid fittings and Surge Suppressor require
torqueing during pump installation. See Section 2 for hook- up
diagram and torque values

PAGE 4 MODEL 110R PUMP OPERATION / MAINTENANCE MANUAL
Figure 1-1
ATTENTION: The pump should be operated with clean, dry air or nitrogen.
Particulate, water and oils in the air supply can damage the pump.
NOTE:
1. It is recommended that a filter be placed on the discharge side of the pump.
2. Although extensive efforts are made to deliver pumps to our customers
completely dry, new pumps may contain residual moisture from their final DI
water test.
Recommended Maximum Operating Levels:
Maximum supply CDA/N2 pressure: 60 psig (4.1 bar)
Maximum fluid temperature: 212°F (100°C)

MODEL 110R PUMP OPERATION / MAINTENANCE MANUAL PAGE 5
See Section 4.1 Preventative Maintenance Schedule for additional requirements
for high temperature applications.
1.4 CHECK MUFFLER OPERATION
1.4.a Purpose
Permits pump to operate reliably in systems that incorporate a discharge fluid
“dead head” condition. (Fluid discharge line closed while pump air supply
remains on.)
Permits pump to operate reliably in systems that have the pump located at an
elevation below the liquid supply level. (Pump air supply remains on.)
Effectively reduces the amount of harmful acid vapors that can enter into the
pump’s internal air circuit components while the pump air supply is off. (A
common cause of shuttle and pilot valve failures.)
1.4.b Adjustment
The Check Muffler is preset at the factory to a setting that makes the pump
“Dead Cycle” at a slow constant rate with the fluid discharge port closed, and
the pump air supply at 45 psig. This setting also allows the pump to operate
with approximately 4 ft. (1 meter) of H2O positive fluid supply pressure.
“Deadheading” at other air supply pressure or with more positive fluid supply
pressure (fluid source above pump) may require user adjustment. The
adjustment should control the pump to a slow, steady “Dead Cycle” rate with
no erratic cycling, ”machine gunning”, evident.
NOTE: If pump application does not require operation in either of these
conditions, loosen check muffler adjustment for minimum restriction.
NOTE: Air consumption during “Dead Cycling” is very little since the pump
diaphragms are displacing only internal bypass. “Dead Cycling” should be
considered as a normal standby idle mode.
Figure 1-2
Turn adjustment screw clockwise (CW) to increase backpressure.
Turn adjustment screw counter-clockwise (CCW) to decrease backpressure.
NOTE: Loosen locking nut prior to making adjustment and then re-tighten nut to
maintain adjustment.

3 START-UP
Pump air supply pressure should be regulated
Open the fluid suction (IN) line valve, if necessary.
Open the fluid discharge (OUT) line valve, if necessary.
Start with air regulator at low pressure setting. Increase or decrease
pressure to attain desired flow, up to 60 psig (4.1 bar) at the pump.
Table 1: Consumption / Efficiency can be used to determine approximate air
consumption.
Refer to Troubleshooting, Section 5, if pump fails to start.
ATTENTION: Prolonged periods (>5 Minutes) of dry running will damage critical
internal pump parts.
CAUTION: When handling potentially dangerous fluids under pressure,
the pump and its fittings should be placed in an enclosure.
3.1 HIGH TEMPERATURE OPERATION
Pump operation at temperatures above 60C requires periodic tightening of the
tie bolt nuts. The frequency of this procedure is best established by the user.
Refer to Section 4 on Maintenance.
3.2 PERFORMANCE CHARTS
Pumping capacity is a function of air supply pressure and volume, suction head,
suction line restrictions, discharge head, discharge line restriction, and fluid
specific gravity and viscosity.

4 MAINTENANCE
Trebor pump maintenance can be divided into two categories: air system
maintenance and fluid system maintenance. The purpose of air system
maintenance is to prevent air system failures such as stalling or erratic cycling.
The purpose of fluid system maintenance is to maintain suction and lift
capabilities.
Pump Rebuild Service
Trebor International provides a factory rebuild service for customers using Trebor
products. Trebor will rebuild any standard pump (exclusive of options). Please
contact Trebor International Sales Department for current rebuild pricing. The
fixed rebuild price includes a factory rebuild and parts equivalent to the standard
rebuild kit. Each factory rebuild comes with a new one-year warranty. Repairs
requiring more extensive part replacements will be quoted prior to proceeding
with the pump rebuild. If the pump has exceeded its useful life and cannot be
rebuilt, the customer may elect to purchase a new Trebor pump. If the customer
chooses not to rebuild or replace the pump, a $150.00 evaluation charge will be
required.
All returned pumps are to be shipped freight prepaid with a valid Purchase Order
for the cost of rebuild service. Please contact Trebor International prior to
returning your pump to obtain an RMA Number and Pump Return Data Sheet to
ensure proper safety precautions. Each pump will be evaluated and repaired
within 5 working days of the receipt of pump at Trebor facility.
4.1 PREVENTIVE MAINTENANCE SCHEDULE
The following maintenance schedule is recommended to optimize pump
performance and minimize failures. Tie bolt torque should be checked within 30
days of start-up and at periodic intervals thereafter. If the pump is subjected to
thermal cycle operation, the tie bolt torque should be checked after the first 3
thermal cycles and periodically thereafter. Certain operating conditions that
require more frequent maintenance intervals have been noted. In positive
pressure inlet conditions where suction or lift is not required, fluid system
maintenance may be extended. However, tie bolt retorque is still recommended.
Adhering to the recommended preventative maintenance schedule along with
periodic inspection of the pump will ensure continued efficient operation and
overall reliable pump performance.
It is recommended that the Preventive Maintenance Record (Section 4.1.a) be
copied, maintained and kept with this unit for future reference.

4.6 CLEAN-UP
The pump fluid cavities may be flushed clean by cycling with the suction (IN) and
discharge (OUT) lines connected to a DI water flushing or rinsing tank. Flushing
using an external pressure source without allowing the pump to cycle will result in
incomplete removal of potentially dangerous chemicals.
NOTE: To effectively eliminate chemical contamination, the pump should cycle
for 10-15 minutes using the flushing DI water as described above.
4.7 DISASSEMBLY
During the life of the pump it will be necessary to perform certain preventative
maintenance procedures to ensure continued high performance operation. This
section and the next (4.8 Assembly) are provided for the user’s convenience in
disassembly and re-assembly procedures.
Thoroughly clean / flush the pump using DI water (Refer to Section 4.6
Clean-Up).
Unlock pump from quick release base by pulling out locking lever on front of
base. Then slide pump forward until it stops. Lift pump off base.
Remove check muffler assembly.

MODEL 110R PUMP OPERATION / MAINTENANCE MANUAL PAGE 15
Remove tie bolt caps from both heads.
Remove un-tact flanged nuts from the tie bolt assemblies (Master Head side).
Using both 3/8” nut drivers. Leave tie bolts in place.
Lay the pump on the slave head side.
Remove the master head.
Remove the main seal and diaphragms.
Remove the main transfer tube and seal.
Remove the pilot transfer tube seal.
Remove the body assembly.
Remove the pilot transfer tube and seal and the second main transfer tube
and seal.
Remove the slave side set of diaphragms and main seal.
Remove tie bolts.
NOTE: All polypropylene and fluoroplastic parts, when disassembled, should be
thoroughly washed and be free from acid residue for handling purposes.
4.7.a Body Disassembly
Remove check bore caps using ½” pin tool and remove seals.
Remove sleeves with sleeve removal tool, check balls and O-rings.
Unthread one push plate from the shaft.
Remove remaining push plate and shaft from body.
Unthread second push plate from shaft.
Remove shaft seals from the shaft bore; taking care not to damage the shaft
bore or shaft seal grooves.
4.7.b Head Disassembly
Remove the shuttle cap from the master head.
Remove the detent and shuttle spool. See Section 4.4 for shuttle detail. (A
small blast of air into the air inlet port will normally cause the detent and
shuttle spool to pop out.)
Remove the shuttle sleeve from the shuttle bore.
NOTE: The shuttle spool, sleeve and the exterior of the detent may be cleaned
with isopropyl alcohol. Do not disassemble or remove lubricant from detent. If
lubricant is lost, it is necessary to replace the detent to avoid damage to the
shuttle spool.
Remove the pilot valves from the master and slave heads, with 1/2” nut
driver.

4.8 ASSEMBLY
4.8.a Head Assemblies
Pilot Valve (Both Heads)
Install the pilot valves with 2 wraps of TFE thread tape in each head.
Figure 4-1
Shuttle Assembly (Master Head)
NOTE: Ensure that the shuttle spool moves freely inside the shuttle sleeve prior
to installation. Never lubricate spool or sleeve.
Check the shuttle assembly making sure it has notched O-rings on each end.
(See Section 4.4 for shuttle detail.)
Insert shuttle sleeve into the shuttle bore.
Insert shuttle spool.
Insert detent.
Install shuttle cap with 2 wraps of TFE tape.

MODEL 110R PUMP OPERATION / MAINTENANCE MANUAL PAGE 17
4.8.b Body Assembly
NOTE: Check sleeves that fit too tightly for easy installation should be placed in
a freezer prior to assembly to assist insertion.
Figure 4-2
Insert suction sleeve, check ball and O-ring carefully into check bore.
NOTE: The Suction Sleeves have a shoulder diameter larger than their body
diameter. Additionally the Suction Sleeves when compared to the Discharge
Sleeves have a thicker top region which acts as a robust contact point for the O-
rings.
Repeat insertion process with the discharge sleeve, check ball and O-ring.
Repeat process for second check bore.
Replace check cap seals and tighten check bore caps to 35in-lbs.
Install shaft seals into shaft bore grooves.
Thread shaft into push plate until engagement with the shaft shoulder is
achieved. Additionally apply a ¼” turn to ensure proper installation.
Insert shaft through shaft bore using shaft bullet as shown (This prevents
damage to the TFE shaft seals and prevents dislodgement of shaft seals).

PAGE 18 MODEL 110R PUMP OPERATION / MAINTENANCE MANUAL
Figure 4-3
Remove bullet and thread on remaining push plate, tighten per previous
practice.
4.8.c Final Assembly
Insert tie bolt assemblies through slave head and lay flat with tie bolts sticking
up.
Place main seal O-ring into the main seal groove in slave head.
Install a diaphragm set, removing all air from between diaphragms, onto the
tie bolts noting the relative orientation of the formed main seal groove in the
diaphragms with respect to conforming to the main seal. Also note air
transfer port hole alignment.
Place one main transfer tube with seal into respective port.
Place pilot transfer tube and one seal into slave head.
Carefully place and press the body assembly onto the tie bolts, transfer
tubes, seals, and slave head.
Install the remaining diaphragm set onto the tie bolts and body, again noting
formed main seal groove and transfer port seals (O-rings).
Install O-ring onto protruding pilot transfer tube.

Must be 10-15 psi greater than fluid discharge line
pressure.

Insufficient air volume.

See performance Chart (Section 3.2) for requirements.

Dirty or damaged shuttle valve.

Clean shuttle spool/detent and sleeve until free movement
is assured (see 4.8.a), or replace.
Use clean dry air or nitrogen.

Pilot valve improperly installed,
diaphragms do not move sufficiently to
activate pilot (bleed).

See 4.8.a.

New diaphragms installed. Not
stretched enough to allow contact with
pilot valves.

Increase air pressure up to 60 psig until pump starts.
Decrease for proper flow if necessary.

Both diaphragms expanded into contact
with pilot valves due to excess fluid
supply line pressure.

Adjust check muffler assembly (see 0).

Fluid discharge line blocked.
Downstream valve closed, filter
plugged, or other obstruction (dead
head).

Remove obstruction. Refer to Section 0 for further
information on “Dead Head” condition.

Shuttle valve spool may be centered.

Turn off air supply. Disconnect supply tube at pump fitting
to bleed internal pressure. Reconnect and turn on air.
Remove shuttle cap and push the spool to end of travel.
Replace cap, start pump.
Bubbles in Fluid Discharge
Cause:
Solution:

Leaking fluid inlet fitting.

Tighten, or remove and wrap with TFE thread tape prior to
tightening.
Replace seals (adapter port options).

Leaking main seal.

Tighten tie bolt nuts to 32 in-lbs. Replace diaphragms if
damaged.

Ruptured (perforated) diaphragm.

Replace Diaphragms.
Fluid Leaks
Cause:
Solution:

Tie bolt torque not enough to effect
seal.

Tighten all nuts to 32 in-lbs.

Damaged main seal.

Replace.
Check for irregularities in diaphragm groove on pump
body.

Check bore cap.

Tighten, or remove and replace seal.

Ruptured diaphragm(s) can result in
fluid leaks through air exhaust port and
shuttle valve.

Replace diaphragms, and any parts that may have been
damaged by fluid exposure.
