Cat Pumps’ direct-drive pumps offer a compact and cost-effective pump mounting, and are available for electric and engine drives. This option allows for easy installation with the pump mounting directly to the motor or engine.
For electric motor direct-drive pumps there are two options available: hollow shaft pumps and bell housing. The hollow shaft pumps fit 56C or 184TC face motors and will bolt directly to the unit. The bell housing mount utilizes a flex coupler between the pump and motor shafts, and the bell housing mounts the pump to the motor. Bell housing direct-drive pumps are commonly used up to 15 HP.
For engine direct-drive pumps there are two options available: hollow shaft pumps and gearbox pumps. Both options bolt directly to the engine, but the gearbox version allows the pump to run at half the speed of the engine.
