Masterflex 07090-42 Instruction Manual
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: 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.

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.
nn To seal, use PTFE tape on threads.
CAUTION: Hand-tighten only. Over-tightening can damage the
PTFE parts.
nn Test the new CHECK VALVE performance by pumping some fluid
under operating conditions.
(4) How to Replace Reagent Head
nn For replacement of the REAGENT HEAD (Part No. D-2027), see
preceding instructions for DIAPHRAGM replacement.
