1 INSTALLATION
1.1 UNPACKING
After unpacking, the pump should be checked for any damage that may have occurred
during shipment. Damage should be reported to the carrier immediately.
The following items should be included within the shipping container:
1.2 TIE BOLT TORQUE
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 17 in Figure 4-1) from both sides of all 8 tie
bolts6
2. Apply 80 in-lbs. (9.0 N-m) 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 the 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 ability and pumping
efficiency.
Air Inlet: 3/8” FNPT (3/8” Dia. [8mm] supply tube minimum).
Air Supply: 25-80 psig (0.17-0.55 MPa) clean dry air or nitrogen. (For Air
Consumption, See 3.2 Performance Charts)
Fluid Ports: Inlet/Outlet Fluid Fittings and Surge Suppressor require tightening to
specified torque values during pump installation. See section 2.2 for
installation diagram and torque values.
Remote
Exhaust: 3/8” FNPT (3/8” Dia. minimum tube up to 6’ length, 1/2” Dia. Minimum
tube greater than 6’ length).
MEGA 120E PUMP OPERATION / MAINTENANCE MANUAL PAGE 3

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.
PAGE 4 MEGA 120E PUMP OPERATION / MAINTENANCE MANUAL
Page 5
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: 80 psig (0.55 MPa)
Maximum fluid temperature: 212°F (100°C)

Install 3/8 NPT leak probe fitting into port. See Figure 2-3 for illustration.
Install probe assembly into fitting. Probe is self-sealing and does not require
a seal.
Tighten nut hand-tight.
Connect fiber optic cable to sensor (NOTE: Minimize bends in fiber optic
cable to 2” radius minimum to help ensure optimum signal strength.). Fiber
optic cable can be cut to desired length using the cable cutter provided.
2.3.b Removal
Remove nut from fitting.
Remove probe.
2.3.c Sensor Signal Specifications
The sensor signal is normally closed. In the event of a leak, no light signal is
returned to the sensor.

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 (<15 psig). Increase or
decrease air pressure to attain desired flow, up to 80 psig (0.55 MPa).
Refer to Troubleshooting, Section 5, if pump fails to start.
ATTENTION: Prolonged periods of dry running (>5 minutes) 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.
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 properties. The
following data was taken using water at atmospheric temperature and pressure with
limited sample sizes. The data is intended to aid in system design and should be used
for general reference only.

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 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.
