The GRACO A25155 Python is a pneumatically operated chemical injection pump designed for safe and reliable chemical transfer in hazardous environments. It features a 1-3/4 inch air motor, a 3/4 inch plunger, and HNBR (Hydrogenated Nitrile Butadiene Rubber) seals for enhanced chemical resistance. This pump is intended for use in industrial applications requiring precise chemical injection and is ATEX approved for use in explosive atmospheres.

Key Features:

• Pneumatic Chemical Injection Pump
• 1-3/4 in Air Motor, 3/4 in Plunger
• Robust industrial design with HNBR seals
• Designed for use with a wide range of chemicals, compatible with regulated natural gas or compressed air
• ATEX Approved (for use in explosive atmospheres)
• Pneumatically operated for safe use in hazardous locations
• Durable HNBR seals for chemical resistance
• Reliable and easy to maintain
• Operates in a wide environmental temperature range (-40° to 176°F / -40° to 80°C)
• Low noise operation (<70 dBa with included muffler)
• Includes adapters for various inlet/outlet sizes

Applications:
Ideal for chemical injection in hazardous environments such as oil and gas, mining, and industrial processing. Suitable for applications requiring precise, reliable, and safe chemical transfer.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump.
• Mount the pump securely and connect the chemical supply as per the manual
• Install a y-strainer or chemical filter before the pump inlet to prevent debris from reaching the pump seals
• Ensure all air and fluid lines are properly connected and leak-free
• A pressure relief valve is recommended and can be connected back to the tank or directly to the inlet side of the pump
• For non-standard installation configurations, consult a GRACO distributor for assistance
