Hydra-Cell H25EKCGHFEHA Cast Iron Seal-less Diaphragm Pump
The Hydra-Cell H25EKCGHFEHA is a rugged, cast iron seal-less diaphragm pump built for industries that need dependable, leak-free performance day after day. Rated for up to 20 GPM, this pump handles everything from clean water to corrosive chemicals, abrasive slurries, and fluids loaded with suspended solids, without the wear-and-tear problems that come with traditional sealed pumps. Because there are no dynamic seals, packing, or cups to break down, operators get long stretches of trouble-free service and far less time spent on maintenance.
What sets this pump apart is how well it copes with harsh operating conditions. It can run dry without damage, work safely against a closed inlet, and keep the pumped liquid fully contained so there's no risk of fugitive emissions. That combination makes it a smart choice for facilities dealing with hazardous or environmentally sensitive fluids, where a single leak could mean costly downtime or compliance headaches. The cast iron head adds extra durability for demanding industrial settings where a lighter-duty pump just won't hold up.
Beyond the toughness, this pump is genuinely easy to live with. Its straightforward, compact design keeps upfront and ongoing costs lower than many comparable pumps, and the stainless steel valve components paired with a Viton-XT diaphragm mean it's built to handle a wide range of fluid types without constant part swaps. Whether it's supporting a manufacturing process, an industrial wash-down system, or a fluid transfer application, the H25EKCGHFEHA is engineered to keep running when it matters most.

Frequently Asked Questions
Q: Can the Hydra-Cell H25EKCGHFEHA run without damage if it loses prime?
A: Yes, this pump is designed to run dry indefinitely without sustaining internal damage, which sets it apart from most conventional pumps.
Q: What types of fluids is this pump best suited for?
A: It's well suited to corrosive, abrasive, and high-viscosity fluids, including slurries and liquids with suspended solids, thanks to its seal-less construction and durable internal components.
Q: How does the seal-less design reduce maintenance needs?
A: Without dynamic seals, packing, or cups to wear out, there are far fewer points of failure, which translates into less frequent part replacement and lower long-term maintenance costs.
Q: Is this pump appropriate for hazardous or emission-sensitive environments?
A: Yes, the fully contained pumping chamber prevents fugitive emissions, helping facilities meet strict environmental and safety requirements.
Q: What maintenance does the oil system require?
A: The pump uses 10W30 standard-duty Hydra-Oil with a 3.3 US quart capacity, and regular oil checks help maintain consistent performance over time.
