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 UTILITIES / HOOK-UP
It is recommended that the pump be positioned within 15° from level to maintain
self-priming ability and pumping efficiency. Allow sufficient room for tubing
connectors. The pump mounting is shown in Fig. 1-1 below.
Air connections are typically made using 3/8” OD x 1/4” ID tubing up to 12 ft. If
more distance is required it is recommended to increase tubing size to ½” tube
for the air lines to minimize losses.
Air Inlet: 3/8” FNPT (3/8” Dia. [8mm] supply tube minimum).
Air Supply: 20-80 psig (1.4 – 5.5 bar) clean dry air or nitrogen (see
Performance Charts, Section Error! Reference source not
found.).
Fluid Ports: 1” NPSM – additional adaptor port options available.

Pump air supply pressure should be regulated. (See Figure 3-2: Pressure
vs. Fluid Temperature Chart.)
Open the fluid suction (IN) line valve, if necessary.
Open the fluid discharge (OUT) line valve, if necessary.
Start with air regulator at low (> 20 psi) pressure setting. Increase pressure
to attain desired flow, up to the maximum rating (See Section 3.1).
Table 1 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 can damage critical
internal pump parts.
CAUTION: When handling potentially dangerous fluids under pressure,
the pump and its fittings should be placed in a compatible enclosure.
3.1 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. 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.
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 0) be
copied, maintained and kept with this unit for future reference.
