🛠️ CAT 2SFQ42SEEL 316SS Direct Drive Plunger Pump (Quiet Model)
🌟 Product Description
The CAT 2SFQ42SEEL is the premium model in the SF series, offering the highest flow rate combined with the noise reduction technology. This triplex Plunger Pump end is built with a rugged 316 Stainless Steel manifold, making it the ideal choice for demanding commercial and industrial Reverse Osmosis (RO) systems where high output and minimal sound pollution are required. The "Q" designation indicates a quieter operation, reducing noise levels by -6 dBa compared to standard models. It delivers a superior flow of 4.2 GPM at pressures up to 1,200 PSI, meeting the rigorous standards for high-capacity brackish and seawater desalination without unnecessary operational noise.
-
High-Capacity & Quiet: Delivers 4.2 GPM flow at 1,200 PSI while featuring CAT's "Q" Quiet Technology for reduced noise levels.
-
Corrosion Immunity: Constructed with a 316 Stainless Steel fluid end for exceptional longevity and chemical compatibility in corrosive feedwater applications.
