Hydra-Cell D04XABTHFEHG Brass Sealless Diaphragm Pump – 2.9 GPM
The Hydra-Cell D04XABTHFEHG is a shaft-driven, sealless diaphragm pump built for jobs where ordinary pumps give out. Instead of relying on mechanical seals, packing, or cups that eventually wear down and leak, this pump uses a multiple-diaphragm design that keeps the fluid path fully enclosed. That means it can run dry without damage, handle abrasive particles and suspended solids, and keep moving liquid reliably even in tough, unforgiving conditions.
Its brass pump head and Buna-N diaphragms and O-rings make it a solid choice for general industrial fluid transfer, coolant delivery, and moderate chemical compatibility applications where cost-effective materials are preferred over stainless steel. With a maximum flow of 2.9 GPM and the ability to push pressures up to 2500 PSI, it strikes a balance between compact size and genuine muscle, all while producing a smooth, low-pulsation flow that reduces stress on downstream components.
The solid shaft configuration is built for direct coupling to a motor, giving installers a straightforward way to integrate this pump into new or existing equipment layouts. Combined with 17-4 stainless valves, tungsten carbide or stainless valve seats, and Elgiloy springs, the internal components are engineered to hold up under repeated high-pressure cycles, making this a dependable long-term workhorse rather than a short-term fix.

Frequently Asked Questions
Q: Can the D04XABTHFEHG run dry without being damaged?
A: Yes, its sealless diaphragm design allows it to run dry indefinitely without harming internal components.
Q: What kind of fluids is this pump best suited for?
A: It works well with low-to-high viscosity fluids, including abrasive liquids, slurries, and general industrial chemicals, thanks to its Buna-N diaphragms.
Q: Does this pump need a separate motor and coupling?
A: Yes, it is shaft-driven with a solid shaft, so it requires a compatible motor, adapter, and shaft coupling to complete the assembly.
Q: How does the diaphragm design reduce maintenance compared to standard pumps?
A: Because there are no seals, packing, or cups to wear out and leak, maintenance needs and downtime are significantly reduced over time.
Q: Is this pump suitable for non-marine industrial settings?
A: Absolutely, it is widely used across manufacturing, machining, chemical processing, and general industrial fluid-handling environments, not just marine or washdown applications.
