OPERATING MANUAL

PTFE DIAPHRAGM PUMP

MODEL NO. 07090-42

All wetted surfaces are of PTFE. This heavy-duty, drive-operated pump is built to deliver virtually any corrosive chemical without harm to its components. Or, the purest fluids can be delivered without risking contamination from the pump. The 07090-42 PTFE Diaphragm Pump handles intermediate size flows (up to 800 mL/min) of a wide range of concentrations and viscosities. It can also pump fluids through filters and other restrictions, and can pressurize containers.

Flexibility? The PTFE DIAPHRAGM PUMP can be teamed-up with your existing MASTERFLEX® L/S® variable speed drive (10:1) range.

WARNING: THIS PUMP IS CAPABLE OF DEVELOPING PRESSURES IN EXCESS OF

THE MAXIMUM RATED 100 PSIG INTERMITTENT DUTY. APPROPRIATE

PRECAUTIONS SUCH AS A PRESSURE RELIEF VALVE MUST BE

INSTALLED TO PROTECT THE PUMP AND ANCILLARY CONNECTIONS

FROM ACCIDENTAL OVER-PRESSURIZATION.

SAFETY PRECAUTIONS

WARNING: PRODUCT USE LIMITATION

This product is not designed for, nor intended for use in patient connected applications; including, but not limited to medical and dental use, and accordingly has not been submitted for FDA approval.

WARNING: CHECK VALVES are intended for use on this pump only. Do

not use separately from the pump as forward flow at higher flow rates will suddenly restrict, causing a rapid increase in backpressure with resultant hose and connection bursting.

INTRODUCTION

The instructions in this manual are task-oriented for easy reference. You can go directly to a particular section and quickly find the answers to your questions. The step-by-step installation and operating instructions are easy to follow.

Also for easy reference, the component designations used in the illustrations are CAPITALIZED in the text.

IMPORTANT: It is essential that the inlet end of the CHECK VALVE be installed in the INLET PORT of the REAGENT HEAD. Similarly, the outlet end must be installed in the OUTLET PORT.

See Fig. 6 for the correct orientation. The ball seats in the end shown. When assembled, you can see the ball through the outlet end of the CHECK VALVE. The pump will not operate unless the CHECK VALVES are properly installed.
