Hydra-Cell M03XAPGSFECA – 3 GPM Polypropylene Diaphragm Pump for 56C Motors
The Hydra-Cell M03XAPGSFECA is a seal-less, multiple-diaphragm positive displacement pump built for operators who need dependable, leak-free fluid transfer without the maintenance headaches of packing or mechanical seals. Rated for up to 3 GPM at 1750 RPM, this pump-only unit features a hollow drive shaft that slides directly over a NEMA 56C motor shaft, eliminating the need for a separate coupling or guard. Its polypropylene pump head makes it a smart choice for handling mildly corrosive or aggressive chemicals that would damage metallic pump components over time.
What sets this pump apart is how it behaves when things don't go perfectly. Because there are no seals to wear out or shafts to leak, the M03XAPGSFECA can run dry indefinitely and even push against a closed or blocked discharge line without sustaining damage. That kind of tolerance is a real advantage in applications where flow can be interrupted unexpectedly, such as chemical injection systems, irrigation setups, or industrial process lines where valves open and close on a schedule outside the pump's control.
This isn't a pump limited to one industry. While Hydra-Cell pumps are common in marine and shipboard systems, the M03XAPGSFECA is just as at home in agricultural fertilizer dosing, water and wastewater treatment, car wash and pressure washing equipment, greenhouse humidification, catalyst injection, and general industrial fluid transfer. Anywhere a facility needs consistent, low-flow, leak-free pumping of chemicals or process liquids, this pump is built to deliver.

Frequently Asked Questions
Q: What motor does the Hydra-Cell M03XAPGSFECA require? A: It's designed to close-couple directly to a NEMA 56C footed motor. The pump's hollow shaft slides over the motor shaft, so no separate coupling or guard is needed.
Q: Can this pump handle abrasive or corrosive chemicals? A: Yes. The polypropylene pump head and FKM diaphragm material give it good resistance to a wide range of corrosive and aggressive fluids, though extremely abrasive slurries should be reviewed against the manufacturer's compatibility guidance before use.
Q: Is this pump only suitable for marine use? A: No. While Hydra-Cell pumps are widely used in marine systems, this model is equally suited to agricultural, industrial, water treatment, and chemical processing applications on land.
Q: What happens if the pump runs dry or the line gets blocked? A: The seal-less diaphragm design allows the pump to run dry indefinitely and withstand a blocked inlet or discharge without internal damage, which is a key advantage over seal-based pumps.
