The CAT Pumps 3560 is a heavy-duty, positive displacement triplex plunger pump from the 35-Frame series, engineered for high-performance fluid transfer in industrial and commercial environments. The pump is constructed with a forged brass inlet manifold and a high-strength 316 Stainless Steel block-style discharge manifold. This dual-metal design provides the durability required to handle high-flow, high-pressure demands, offering resistance to corrosion and cavitation. The internal mechanism features concentric solid ceramic plungers that minimize friction against the seals, extending the maintenance interval for the drive-end and wet-end components.

Designed to deliver consistent, low-pulsation fluid output, the 3560 is suitable for large-scale liquid handling, industrial fluid transfer, and high-intensity cleaning systems. It features matched connecting rods and oversized bearings to ensure stability during continuous-duty operation. The pump operates at a rated flow of 20 GPM and a maximum pressure of 4000 PSI, making it a capable solution for critical systems where downtime must be minimized. The standard NBR (Buna-N) seals effectively manage temperatures up to 160°F, providing versatility across a wide range of industrial environments.
