Frequently Asked Questions

Yes. It is listed as a replacement fluid section for both GMax 7900 and GH 200, as well as the LineLazer IV 250SPS and LineLazer III 200HS.

The pump is rated up to 3,600 psi (250 bar). Fluid inlet is 1 npsm (male) and fluid outlet is 3/8 npt (female).

Check your machine’s model, series (e.g., Series A), and serial range. Compare the fluid section number on your existing pump or consult the parts manual for your unit’s bill of materials.

In most cases yes, provided they match the listed inlet/outlet thread sizes and are rated above your operating pressure. Inspect and replace worn seals and filters during installation.

Flush with compatible solvent after use, keep filters clean, use recommended packings/lubricants, and avoid running the pump dry. Replace worn check balls and seats as needed.
