Description
The GRACO A25402 is a pneumatically operated chemical injection pump designed for high-pressure fluid transfer and chemical injection applications. It features a 4-1/2 inch air motor, a Chromex coated 1/2 inch plunger, and FKM (fluorocarbon) seals for chemical resistance. This pump is intended for use in industrial environments where reliable, continuous chemical injection is required.
Key Features:
- Pneumatic chemical injection pump
- Python XL, 4-1/2 in Air Motor, 1/2 in Plunger
- Chromex coated plunger, FKM seals, robust metal housing
- Capable of operating up to 12,000 psi (see manual for specific model limits)
- Designed for chemical injection in industrial applications; compatible with various chemicals due to FKM seals
- CE Approved
- Double-acting operation (for continuous flow and prevention of air locking in XL-DA models; standard XL models may be single-acting)
- Easy to operate and maintain
- Proven air motor technology
- Suitable for harsh environments (-40 to 176F / -40 to 80C)
- Low noise operation (sound pressure: 70.2 dBA for 4.5 in air motor)
- Reliable, robust construction for long service life
Applications:
Industrial chemical injection, lubrication systems, oil and gas, mining, agriculture, and other sectors requiring precise, high-pressure chemical delivery.
Installation Notes:
- Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing systems.
- Follow the manufacturers instruction manual for specific installation procedures
- Ensure proper alignment and secure mounting
- Use recommended fittings and tubing for inlet/outlet connections (1/4 in. NPT(f) inlet, 1/4 in. NPT(f) outlet for 1/2 in. plunger models)
- Check for leaks and proper air supply before operation
- Regularly inspect seals and plunger for wear and chemical compatibility
