Hydra-Cell D03XKSGHFECA 3.1 GPM Solid Shaft Diaphragm Pump
The Hydra-Cell D03XKSGHFECA is engineered for facilities that need dependable fluid transfer without the leaks, wear, or downtime that come from conventional seal-based pumps. Built around a 316 stainless steel pump head with Viton-XT diaphragms and O-rings, it moves up to 3.1 GPM at 1750 RPM while standing up to a broad range of corrosive, abrasive, and non-lubricating liquids that would quickly damage typical pump designs.
What sets this pump apart is its seal-less, diaphragm-based construction. There are no packing glands, cups, or mechanical seals to wear out, which means it can run dry indefinitely and safely handle a closed or restricted inlet without damage. Only the diaphragms, O-rings, and check valves ever contact the pumped fluid, so maintenance stays simple and infrequent — most operators see thousands of hours of continuous service before check valve attention is needed. The solid shaft design gives installers the flexibility to couple the pump to the motor of their choice, making it a natural fit for custom skid builds, retrofit projects, and OEM equipment.
From chemical metering and dosing to agricultural fertilizer application, industrial process fluid transfer, humidification systems, and reverse osmosis pre-treatment, the D03XKSGHFECA adapts to a wide variety of environments. Its combination of stainless steel durability and Viton chemical resistance makes it a practical choice anywhere consistent, leak-free performance is non-negotiable.

Frequently Asked Questions
Q: What is the difference between the D03 and M03 Hydra-Cell pump series?
A: The D03 uses a solid, shaft-driven design that requires a separate motor and shaft coupling, while the M03 has a hollow shaft that mounts directly to a 56C NEMA frame motor, eliminating the need for a coupling.
Q: Can the D03XKSGHFECA run dry without being damaged?
A: Yes, its seal-less diaphragm design allows it to run dry indefinitely and operate safely against a closed or restricted inlet without harming the pump.
Q: What fluids is this pump compatible with?
A: The 316 stainless steel pump head and Viton-XT diaphragms and O-rings allow it to handle a wide range of corrosives, abrasives, slurries, and non-lubricating fluids.
Q: Does this pump include a motor?
A: No, the D03XKSGHFECA is sold as a pump only and requires a separately sourced motor and shaft coupling for operation.
Q: How often does this pump require maintenance?
A: Since only the diaphragms, O-rings, and check valves contact the fluid, wear is gradual and typically only the check valves need service, often after thousands of hours of continuous operation.
