SF SERIES PUMPS
Industrial Duty Compact Direct-Drive Pumps
Cat Pumps’ direct-drive pumps offer a compact and cost-effective solution for both electric and engine drives, allowing easy installation by mounting the pump directly to the motor or engine. The options include:
Electric Motor Direct-Drive Pumps: Choose between hollow shaft pumps, fitting 56C or 184TC face motors, or bell housing mounts utilizing a flex coupler, commonly used up to 15 HP.
Engine Direct-Drive Pumps: Two options—hollow shaft pumps and gearbox pumps—both directly bolt to the engine. The gearbox version allows the pump to run at half the speed for enhanced versatility in various applications.
