Air exhaust (internal silencer):        3/8" Female NPT

■ Polypropylene pumps may be fitted with ball or flat check valves. Ball-type check valves are

recommended for flooded suction applications. Flat-type check valves are recommended for suction lift applications.

◆ Kynar® and Groundable Acetal pumps are fitted with flat check valves only.

▲ Aluminum and Stainless Steel pumps are fitted with ball check valves only.

Maximum Liquid Temperature*

Diaphragm Material Temperature

Buna N                   180°F (82°C)

Neoprene                 180°F (82°C)

Santoprene® (TPO)        180°F (82°C)

PTFE                     212°F (100°C)

Hytrel® (TPEE)           248°F (120°C)

Viton® fluoroelastomer   248°F (120°C)

*The maximum liquid temperature for metal and Kynar® fitted pumps is determined by the elastomer (diaphragm material). Polypropylene and Groundable Acetal pumps have a maximum liquid temperature of 180°F (82°C) regardless of diaphragm material.
