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).

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.
