Hydra-Cell M03XKPJCCTPA 3 GPM Polypropylene Diaphragm Pump with Kel-Cel Head
The Hydra-Cell M03XKPJCCTPA is a seal-less positive displacement pump built for jobs where ordinary pumps tend to fail. Its Kel-Cel polypropylene liquid end resists the corrosive chemicals, acids, and aggressive solutions that would eat through metal housings, while the seal-less diaphragm design means there are no packing glands or mechanical seals to wear out, drip, or replace. This pump can run dry without damage, tolerate suction restrictions, and keep working through the kind of rough treatment that would sideline a typical centrifugal or rotary pump.
With a hollow 5/8-inch shaft designed to slide directly onto a NEMA 56C frame motor, this M03 model skips the need for a separate coupling or guard, simplifying installation and reducing points of failure. It delivers up to 3.1 GPM of steady, low-pulsation flow, making it a practical choice for metering, dosing, and transfer tasks where consistent output matters more than raw volume. Because the diaphragm design isolates the pumped fluid from the gearbox, it also holds up well with abrasive slurries and particulate-laden liquids that would score or clog other pump types.
This configuration is a solid fit for chemical processing, water treatment, agricultural dosing, and general industrial fluid handling where corrosion resistance and reliability under variable conditions are the priority. Its compact, low-maintenance design keeps operating costs down over the life of the pump, and its versatility across fluid types means it isn't limited to any single industry.

Frequently Asked Questions
Q: What does the Kel-Cel designation mean on this pump model?
Kel-Cel refers to the polypropylene construction of the liquid end, which is designed to resist corrosion from aggressive chemicals and fluids that would damage metallic pump heads.
Q: Can this pump handle abrasive or particulate-laden fluids?
Yes, the seal-less diaphragm design and horizontal disk check valves allow it to handle abrasives and suspended solids up to 200 microns without the damage typical seals would suffer.
Q: Does this pump require a separate motor coupling?
No, the M03XKPJCCTPA has a hollow shaft designed to slide directly onto a NEMA 56C frame motor shaft, eliminating the need for a coupling or guard.
Q: What happens if the pump runs dry or the inlet gets blocked?
The pump can run dry indefinitely and tolerate restricted or blocked inlets without sustaining damage, which is a core advantage of the Hydra-Cell diaphragm design.
Q: What types of industries commonly use this pump?
It is commonly used in chemical processing, agricultural dosing, water treatment, catalyst injection, and other applications requiring reliable, corrosion-resistant fluid handling.
