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 4.4 Parts Illustration) from both
sides of all 8 tie bolts.
2. Apply 60 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

2.3 OPTIONAL LEAK SENSING
2.3.a Installation
•Remove plug and seal from port.
•Install probe assembly into leak sensor port. Probe is self-sealing and does
not require a seal.
•Thread probe cap into port. (NOTE: Do not over tighten; damage to threads
will occur.)
•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.
Figure 2-3

PAGE 8 MEGA 960D PUMP OPERATION / MAINTENANCE MANUAL
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 setting
to attain desired flow, up to 80 psig (4.1 bar). Minimum is 20 psig.
•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 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
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.
