CAT Pumps 3507HS 35-Frame Plunger Pump
The CAT Pumps 3507HS is a heavy-duty, positive displacement triplex plunger pump from the robust 35-Frame series. Engineered to withstand rigorous continuous-duty applications, this reciprocating pump features a manifold constructed from high-strength Nickel Aluminum Bronze (NAB) paired with 316 Stainless Steel valve assemblies. This premium metallurgy delivers exceptional resistance to corrosion and wear, making it an optimal choice for high-demand industrial environments, saltwater applications, and large-scale pressure washing systems.
Designed for maximum operational efficiency, the "HS" Series utilizes advanced connecting rod and plunger rod materials to optimize drive-end performance. The pump operates at a powerful flow rate of 10 GPM with a maximum pressure capacity of 5000 PSI at 915 RPM. It is equipped with solid ceramic plungers that provide a true, low-friction wear surface, significantly extending the life of the standard NBR (Buna-N) seals and O-rings. By ensuring low pulsation and highly consistent fluid delivery, the 3507HS provides the reliable, continuous power required for mission-critical liquid transfer and heavy-duty surface cleaning.
