1 INTRODUCTION

PFA injection molded high purity

disposable pump.

TREBOR’S Purus 20 diaphragm pump

addresses maintenance, rebuild, and cost

issues common in many chemical pumps by

using an injection molded PFA design with

minimal welded parts. This design (Figure 1-1)

creates a reliable, disposable pump that costs

less than many competitor pump rebuild kits.

The Purus 20 provides peace of mind because

of its purity, performance, and simplicity.

Purus pumps can be externally controlled or

installed as a self-contained unit using

TREBOR’S PC7 (Figure 1-2) air-powered

pump controller that mounts on the Purus 20,

as shown in (Figure 1-1).

Product Benefits

Operating life exceeding 100 million

cycles in many applications

Excellent suction lift and priming

capability

No elastomer seals or gaskets to replace

No metal parts to corrode or contaminate

process

Compact size

100% PFA/PTFE construction for the

chemical compatibility and process purity

FM4910 compliant

Cleaned, assembled, and packaged in

Class 1000 cleanroom

CE Certified

2 INSTALLATION

2.1 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.

NOTE: 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.

The following items should be included within the shipping container:

2.2 UTILITIES / HOOK-UP

The pump is mounted using four ¼” (6mm) bolts. 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.

Figure 2-1: Dimensions (with mounted PC7 option & flare connection)

P20 PUMP OPERATION / MAINTENANCE MANUAL PAGE 5

Air Inlet: 3/8” OD Tubing)

Air Supply: 20-80 PSIG (0.14 - 0.55 Mpa), clean dry air or inert gas

Fluid Ports: 1/2” Flaretek standard (other options available)

For maximum flow the following is recommended:

1. Maximize supply line diameter

2. Minimize supply line length

3. Minimize supply line restrictions (i.e. valves, fittings)

NOTE: It is recommended that a filter be placed on the discharge side of the pump.

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 6 P20 PUMP OPERATION / MAINTENANCE MANUAL

3 TEMPERATURE AND PRESSURE LIMITS

3.1 HIGH TEMPERATURE OPERATION

The Purus 20 pump is molded out of virgin PFA. This enables high temperature operation

under specific conditions. The maximum temperature will vary in relation to the supply

pressure. Figure 3-1 shows Trebor’s maximum recommended temperature for the pump.

Exceeding the temperature for a corresponding supply pressure could cause the pump to

develop leaks at the pump main seal between the air and fluid chambers.

Figure 3-1: Purus 20 Recommended Temperature Curve

3.2 HIGH BACK PRESSURE OPERATION

Increasing the fluid outlet pressure, or back pressure, causes stress on the pump main

seal. High back pressure, around 90% of the supply pressure, can cause the pump to

develop leaks at the main seal. It is not recommended to run the Purus 20 pump at near

dead head conditions.

High back pressure and elevated fluid temperatures can combine to increase the

likelihood of pump failure due to a main seal leak. Higher temperature reduces the yield

strength of PFA, while higher stresses are induced by the high back pressure. The

combination of those two operating conditions can cause the main seal to unload, which

can lead to a leak. Due to the potential variations in operating conditions, the typical range

of material properties and the tolerance stack up, it is impossible to identify the exact

points where main seal leaks become probable due to temperature/back pressure

interactions.

4 OPTIONS

4.1 FLUID PORT CONNECTION OPTIONS

Additional options are available. Please contact Trebor Sales Department for details

regarding available options.

½” Flaretek (standard)

½” Pillar, Super 300 (optional)

½” PrimeLock (optional)

4.2 HOOK-UP WITH SURGE SUPPRESSOR

For surge suppression, Trebor International recommends the use of the SS40 inline surge

suppressor. Consult factory for installation and performance specifications. Information

also available at www.treborintl.com

NOTE: See Surge Suppressor Operation Manual for detailed installation instructions.

5 START-UP

Open the fluid suction (IN) line valve, if necessary

Open the fluid discharge (OUT) line valve, if necessary

Pump air supply pressure should be regulated

Operate pump at 20 psig initially to prime pump

Increase pressure to attain desired flow, (not to exceed 80 psig)

If the pump fails to start, refer to the troubleshooting section or contact Trebor for

further assistance.

ATTENTION: Prolonged periods (>5 minutes) of running without fluid 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.

5.1 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.
