Operation/Maintenance Manual
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 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 mounts on a quick-change base for easy installation.
The pump has an exhaust location on the backside of the master head. The
exhaust location requires 1/2” (12mm) minimum clearance behind the master
head. Care should be taken to prevent flooding the exhaust port when the pump
is located in a wet bench plenum. For remote exhaust connection see Section 0.
Air Inlet: 1/4” 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 3.1).
Fluid Ports: 1” NPSM – additional adaptor port options available.
Inlet/Outlet adaptor fittings and Surge Suppressor require
torqueing during pump installation. See Section 2 for hook-up
diagram and torque values.

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.

1.3 CHECK MUFFLER OPERATION
1.3.a Purpose
NOTE: The check muffler is not designed to control pump speed. Use of the
check muffler for this purpose could result in serious damage to the pump.
Permits pump to operate reliably in systems that incorporate a discharge flow
less than 3 gpm.
Permits pump to operate reliably in systems that have the pump located at
an elevation below the liquid supply level and flows below 3 gpm. (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.
1.3.b Adjustment
The check muffler has 3 preset arrangements. The pump is shipped from the
factory in the medium back pressure setting, see Mid-Setting in Figure 1-2:
Check Muffler.
Mid-Setting
Start pressure <15 psi
Low flow applications (flow <3 gpm)
The Check Muffler is preset at the factory at the mid-setting. This setting
protects the pump air system from caustic fumes and allows the pump to
maintain a “Dead Head” condition with supply pressures up to 35 psi. This
setting also protects the pump in conditions of positive inlet supplies up to 10
ft. above the inlet of the pump.
High-Setting
Start pressure at <30 psi
Air supply >40 psi, low flow application (flow <3 gpm)
By removing the muffler from the pump and reversing the spring assembly in
the muffler then reinstalling the muffler, the Check Muffler is now set in the
highest back pressure setting. This setting protects the pump from dead
head conditions up to 60 psi, or from positive inlet heads up to 20 ft.
However, this setting is not recommended for operating fluid temperatures
over 60C as damage to the pump shaft can occur. This setting also
diminishes the pump’s flow capacity by 15% from normal published curves.
This setting also increases the pump start pressure from 15 psi to
approximately 30 psi.
Low-Setting (no picture shown)
Spring assembly removed
Start pressure <10 psi
Low back pressure, high flow (>3 gpm) requirement
MAGNUM 620R PUMP OPERATION / MAINTENANCE MANUAL PAGE 5
Page 6
If none of the aforementioned conditions exist when operating the pump,
then the final setting of the check muffler may be used. To obtain maximum
flow capability and lowest start pressure (<10 psi), completely remove the
spring assembly from the check muffler assembly. This is the recommended
condition to obtain best performance and life from the pump. Most normal
open recirculation applications may be operated successfully under this
condition.
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: Check Muffler
PAGE 6 MAGNUM 620R PUMP OPERATION / MAINTENANCE MANUAL
Page 7
1.4 REMOTE EXHAUST HOOK-UP
Some installations may benefit from remotely exhausting air from the pump to
eliminate unwanted air turbulence or to prevent potentially damaging chemical
vapors from entering the pump air cavities.
Remove existing Muffler Assembly from the back of pump head.
Install Exhaust Plug in Exhaust Port.
Install the appropriately sized (3/8” OD) fitting and tubing (not provided) to
remote exhaust. A remote muffler assembly may be installed at the point of
exhaust if required for condition needing the check muffler (see Section
1.3.b).
NOTE: To maintain optimum pump performance use 3/8” (8mm) tubing minimum
at a length of 10 ft. (3 meters) maximum.

3 START-UP
Pump air supply pressure must be regulated. (See Figure 3-3: Pressure vs.
Fluid Temperature Chart.)
Open the fluid suction (IN) line valve, if necessary.
Open the fluid discharge (OUT) line valve, if necessary.
Start slowly 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: 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 can damage
critical internal pump parts.
CAUTION: When handling potentially dangerous fluids under pressure,
the pump and its fittings should be placed in an enclosure away from operators.
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 4.1.a) be
copied, maintained and kept with this unit for future reference.

4.9 TESTING
Performance Test
With the air supply at 0 psi open the air supply valve
Increase the air pressure until the pump starts to cycle
Record the start pressure, Target = 20psig
Pump must prime and even cycling must be achieved
Increase pressure to 60 psi and allow pump to run for 5 minutes
Check for fluid leaks, listen for air leaks, check for irregularity
Prepare the pump for drying
Dry Pump
Connect vacuum hose to discharge line
Connect purge line to fluid inlet
60 psig Supply Pressure
Cycle pump & vacuum dry by rotating pump side to side for 30 seconds.
Turn off Air Supply and allow the pump to purge for 5 minutes.
Dry Suction
20 psig Supply Pressure Target
Record Suction Value
Target = 10 in-Hg.

Pump Will Not Start, Fails to Operate
Cause:
Solution:
Insufficient air pressure.
Must be minimum 12 psig at pump air hook-up.
If check muffler spring assembly is installed at high
setting, start pressure may be up to 35 psi.
Insufficient air volume (low supply
pressure during running).
See Performance Charts (3.1) for requirements. Check
for both regulator and control valve Cv’s >.85 capabilities.
Fluid discharge line blocked.
Downstream valve closed, filter plugged
or other obstruction.
Remove obstruction.
Pilot valve failure.
Inspect and replace pilot valve body and poppet.
Detent failure.
Inspect detent legs for worn or damaged parts.
Bubbles in Fluid Discharge
Cause:
Solution:
Leaking fluid inlet fitting.
Tighten fittings or replace adapter seal.
Leaking main seal.
Tighten heads an additional 15.
Replace diaphragms, and check head and body grooves
for nicks or scratches.
Pump inlet line pressure reached
saturation point (due to high suction
requirement).
Increase diameter of suction supply line (reduces
restriction).
Reduce output flow.
Ruptured (perforated) diaphragm.
Replace diaphragms.
Check bore caps leaking.
Tighten check bore caps or replace seals.
Fluid Leaks
Cause:
Solution:
Head torque not enough to effect seal.
Remove heads and allow to sit for 1 hour. Reassemble
with new diaphragms.
Leaking main seal.
Replace diaphragms.
Check head and body seal grooves for nicks and
scratches.
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.
Erratic Cycling
Cause:
Solution:
Fluid supply inlet pressure too high.
Adjust check muffler per Section 1.3.
Pilot valve failure.
Inspect and replace pilot valve body and poppet.
Suction line restricted (cavitation).
Reduce fluid restriction
Detent failure.
Inspect and replace spool assembly.
Check ball(s) not seating.
Check O-rings for damage; replace if necessary.
Make sure check balls move freely in sleeves.
Over pressurization of pump discharge.
Reduce discharge pressure by reducing restriction.
