Python® Pneumatically Operated Pumps
Designed to operate in potentially explosive atmosphere
Python pumps are ideal for applications that require a pump to operate in an potentially explosive atmosphere and can run off regulated natural gas or compressed air. These pumps have the lowest out of pocket cost, are easy to operate and use half the air consumption of other pumps in the market. Plus, the Python's extreme duty plungers, seals and timing valve are designed for years of operation before replacement.
Operating Environment
The Python is designed to operate in environments from -40°F to 175°F (-40°C to 79°C), made entirely from 316 SST parts and are sealed against water and dust.
Accurate Control
Ultra precision stroke adjustment between 1/4 to 1 inch (6.4 to 25.4 mm) ensures accurate injection rates.
Environmental
Reduced fugitive methane emissions.
Chemical Compatibility
HNBR and FKM plunger packings and check valve seals can handle some of the most aggressive chemicals.
Consistent Operation
Pump cycle rate remains constant regardless of system back pressure..
Plunger Rod
Pythons are offered with Chromex coated plungers as the standard product offering. Ceramic coated plungers are also offered as an option. See page 70 for more information regarding benefits of Chromex and Ceramic plunger rod coatings.
