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.
