Hydra-Cell M03XKPECCTPJ Pump – 3.1 GPM Polypropylene/EPDM Diaphragm Pump for 56C Motors
The Hydra-Cell M03XKPECCTPJ is a seal-less, multiple-diaphragm pump built for operators who need dependable performance without the maintenance headaches of traditional sealed pumps. With a polypropylene pump head and EPDM diaphragms and O-rings, it's designed to move a wide range of fluids reliably, from mild chemicals to fertilizers and other demanding process liquids. Because it uses a hollow shaft configuration, it mounts directly to a NEMA 56C footed motor, which means no coupling or guard is needed, simplifying installation and reducing the number of parts that can eventually wear out.
What makes this pump stand out is what it doesn't have: no mechanical seals, packing, or cups to leak or replace. That seal-less design lets the pump run dry indefinitely and tolerate a blocked or restricted inlet without damage, something that would destroy most conventional pumps. It also means the pumped liquid never has to lubricate or cool the pump internals, so it's well suited to handling abrasive slurries, corrosives, and other fluids that are hard on standard pumping equipment.
Beyond the mechanical advantages, this pump is built with an eye toward lower total ownership cost. The ceramic valves and valve seats resist wear, the Hastelloy valve springs add corrosion resistance, and the only real wear items are the check valve assemblies, which are simple to service without special tools. For facilities running chemical metering, dosing, or fluid transfer applications where uptime and reliability matter, the M03XKPECCTPJ offers a rugged, low-maintenance option that keeps operating costs down over the life of the equipment.

Frequently Asked Questions
Q: Can the M03XKPECCTPJ pump run without liquid in the line?
A: Yes. Its seal-less diaphragm design allows it to run dry indefinitely without damaging internal components.
Q: What motor does this pump require?
A: It is designed to close-couple directly to a NEMA 56C footed motor using its hollow pump shaft, so no separate motor is included and no coupling is required.
Q: What kind of fluids can this pump handle?
A: With its polypropylene head and EPDM diaphragms, it is well suited for a wide range of chemicals, fertilizers, corrosive liquids, and abrasive fluids that would damage conventional sealed pumps.
Q: How often does this pump need maintenance?
A: The main wear items are the check valve assemblies, which typically last thousands of hours of continuous use and can be serviced quickly without specialized tools.
Q: Is this pump suitable for hazardous or regulated environments?
A: Yes, ATEX-compliant versions are available, and the fully contained fluid path helps support environmental and emissions compliance standards.
