Materials of Construction
Product Overview
Thermoplastic Diaphragms and Elastomers
Geolast® - Nitrile based material that replaces traditional Nitrile, Urethane, and Neoprene diaphragms
Santoprene® - EPDM based material with excellent resistance to acids and bases
Product Overview
Thermoplastic Diaphragms and Elastomers
Pumps built with PTFE have a Santoprene® back-up diaphragm which maximizes cycle life.
Competitive pumps without the backup diaphragm have very low cycle life
Viton® is also available as an optional elastomer for many pump sizes
Product Overview
Air-Valve
Dissimilar plastic components used throughout the air system create lubricity - no additional lubrication is needed.
The pilot assembly exerts a constant stream of pressure on one end of the air valve spool, then shifts the pressure stream to the other end which prevents a stall or the dreaded ‘centered’ condition.

Product Overview
Understanding the Pump Curve
Point 1 is the air inlet pressure
Point 2 is the required flow rate
Point 3 is the outlet pressure of fluid
(the right axis converts psig to feet (meters))
Air consumption is designated by the red lines
(the closest iteration to point 2 is approximately 6 SCFM)
Product Overview
Adjusting the Flow Rate
1. Use a pressure regulator to adjust the air pressure. 2. Use an air control valve (ball or needle valve) to adjust the
amount of air going into the pump.3. Using a ball or throttling valve on the liquid discharge side
of the pump.
Product Overview
Viscosity
1. Position pump as close to or below the level of the fluid
2. Use large suction lines - up to 3 times the size of the inlet
3. Start pump slowly using a valve on the air lineProduct Overview
Chemical Compatibility
1. Always select ‘A’ rated material to fluid combinations2. Note all temperature limitations for any given material,
these are referenced by the superscript 1 or 2 (or an exact temperature,
such as 150).3. After finding ‘A’ rated combinations, there may be more
than one possible pump model. Select the pump based on price, application (such as UV exposure) or conditions of usage.

Installation Guidance
1. Use a lube-free, clean, dry, compressed air supply
2. Mount pumps in an upright position
3. Never restrict fluid suction lines
4. Practice preventive maintenance and make sure that the fasteners are at the proper torque
