About
A direct replacement pumphead engineered to mount to standard NEMA 56C motors. Built for fast, quiet, and reliable heavy oil transfer.
- Flow Rate vs. RPM: 12 GPM @ 1800 RPM | 20 GPM @ 2850 RPM | 25 GPM @ 3450 RPM.
- Direct Fit: Flanged for NEMA 56C standard electric motors.
- Shaft Size: Features a 14mm keyed shaft (requires appropriate coupler for your motor).
- Smooth Operation: Large displacement helical-cut steel gears for fast and quiet operation.
- Ready to Plumb: 1" NPT ports (Includes two 1.25" hose barbs).
The ultimate cast-iron replacement pumphead. Engineered to move heavy gear oils, waste motor oil, and diesel, built specifically to mount to standard NEMA 56C electric motors.
In a true heavy-duty fluid transfer system, your electric motor is the expensive workhorse that should last for years. At the same time, the pumphead inevitably takes the abuse of moving heavy, abrasive oils. When your pumphead eventually wears out, there is no need to buy an entirely new system. The W2083 is a cost-effective, direct-replacement pumphead designed for close-coupled pumps with NEMA 56C motors, getting you back to peak pumping efficiency in minutes.
Key Features & Benefits
- Scalable Performance: The flow rate of this pumphead scales perfectly with your motor's speed. Pair it with a 3450 RPM motor for high-speed 25 GPM transfer, a 2850 RPM motor for 20 GPM, or an 1800 RPM motor for high-torque 12 GPM transfer.
- Fast & Quiet Operation: Equipped with large displacement, helical-cut steel gears that provide a nearly pulseless flow, drastically reducing vibration and noise during heavy transfer jobs.
- Universal Fit: Designed as a direct bolt-on fit for NEMA 56C standard electric motors. The pumphead features a 14mm keyed shaft.
- Self-Priming: Creates strong suction lift right out of the box, saving you time and hassle.
